Workspace: Move engines to workspace and Properties Editor cleanup Engine is not stored in WorkSpaces. That defines the "context" engine, which is used for the entire UI. The engine used for the poll of nodes (add node menu, new nodes when "Use Nodes") is obtained from context. Introduce a ViewRender struct for viewport settings that are defined for workspaces and scene. This struct will be populated with the hand-picked settings that can be defined per workspace as per the 2.8 design. * use_scene_settings * properties editor: workshop + organize context path Use Scene Settings ================== For viewport drawing, Workspaces have an option to use the Scene render settings (F12) instead of the viewport settings. This way users can quickly preview the final render settings, engine and View Layer. This will affect all the editors in that workspace, and it will be clearly indicated in the top-bar. Properties Editor: Add Workspace and organize context path ========================================================== We now have the properties of: Scene, Scene > Layer, Scene > World, Workspace [Scene | Workspace] > Render Layer > Object [Scene | Workspace] > Render Layer > Object > Data (...)

View3D: Tweak GLSL preview, use only lamps enabled in active render layer and material light group. This change makes lighting in GLSL preview more accurate, though it still doesn't support material's "Exclusive" option. Technical note: Changes in view3d_draw.c are not essential, these avoid preparing unused shadow buffers.

Implement Uniformbuffer objects for nodetree parameters For users that means you can tweak shaders in the nodetree and things are way faster. This is a huge improvement, particularly in systems that have no shader cache. From the code perspective it means we are no longer re-compiling the shader every time a value is tweaked in the UI. We are using uniforms for those values. It would be slow to add that many uniforms for all the shaders. So instead we are using UBO (Uniform Buffer Objects). This fixes the main issue of T51467. However GWN_shaderinterface_create() still needs to be improvedi. When opening a .blend all shaders are compiled once, so optimizing it will bring a measurable impact. ======================================================================== NOTE: This breaks update of Cycles material upon nodetree nodes tweaking. It will be fixed separately by depsgraph, once tackling T51925 (Animated Eevee values slowdown). The idea is to make Depsgraph update more granular. The XXX TODO in rna_nodetree.c will be tackled at that time as well. ======================================================================== Reviewers: sergey, brecht, fclem Differential Revision: https://developer.blender.org/D2739

Environment lighting for the GLSL mode Environment lighting (aka ambient) is a key component of any renderer. It's implemented like the Environment lighting of BI render for Approximate Gather mode. It support "Sky Color" and "White" Environment lighting modes. It would be great if the user could see actual lighting conditions right in the Blender viewport instead of waiting for the renderer to complete the final image, exporting for external renderer or for a game engine.

Revert particle system and point cache removal in blender2.8 branch. This reverts commit 5aa19be91263a249ffae75573e3b32f24269d890 and b4a721af694817fa921b119df83d33ede7d7fed0. Due to postponement of particle system rewrite it was decided to put particle code back into the 2.8 branch for the time being.

OpenSubdiv: Commit of OpenSubdiv integration into Blender This commit contains all the remained parts needed for initial integration of OpenSubdiv into Blender's subdivision surface code. Includes both GPU and CPU backends which works in the following way: - When SubSurf modifier is the last in the modifiers stack then GPU pipeline of OpenSubdiv is used, making viewport performance as fast as possible. This also requires graphscard with GLSL 1.5 support. If this requirement is not met, then no GPU pipeline is used at all. - If SubSurf is not a last modifier or if DerivesMesh is being evaluated for rendering then CPU limit evaluation API from OpenSubdiv is used. This only replaces the legacy evaluation code from CCGSubSurf_legacy, but keeps CCG structures exactly the same as they used to be for ages now. This integration is fully covered with ifdef and not enabled by default because there are several TODOs to be solved first: - Face varying data interpolation is not really cleanly implemented for GPU in OpenSubdiv 3.0. It is also not implemented for limit evaluation API. This basically means we'll have really hard time supporting UVs. - Limit evaluation only works with adaptivly subdivided meshes so far, which basically means all the points of CCG are pushed to the limit. This gives different result from old code. - There are some serious optimizations possible on the topology refiner creation, which would speed up initial OpenSubdiv mesh creation. - There are some hardcoded asumptions in the GPU and DerivedMesh areas which could be generalized. That's something where Antony and Campbell can help, making it so the code is structured in a way which is reusable by all planned viewport projects. - There are also some workarounds in the dependency graph to make sure OpenGL buffers are only freed from the main thread. Those who'll be wanting to make experiments with this code should grab dev branch (NOT master) from https://github.com/Nazg-Gul/OpenSubdiv/tree/dev There are some patches applied in there which we're working on on getting into upstream.

Implement Uniformbuffer objects for nodetree parameters For users that means you can tweak shaders in the nodetree and things are way faster. This is a huge improvement, particularly in systems that have no shader cache. From the code perspective it means we are no longer re-compiling the shader every time a value is tweaked in the UI. We are using uniforms for those values. It would be slow to add that many uniforms for all the shaders. So instead we are using UBO (Uniform Buffer Objects). This fixes the main issue of T51467. However GWN_shaderinterface_create() still needs to be improvedi. When opening a .blend all shaders are compiled once, so optimizing it will bring a measurable impact. ======================================================================== NOTE: This breaks update of Cycles material upon nodetree nodes tweaking. It will be fixed separately by depsgraph, once tackling T51925 (Animated Eevee values slowdown). The idea is to make Depsgraph update more granular. The XXX TODO in rna_nodetree.c will be tackled at that time as well. ======================================================================== Reviewers: sergey, brecht, fclem Differential Revision: https://developer.blender.org/D2739

Eevee: Initial Separable Subsurface Scattering implementation. How to use: - Enable subsurface scattering in the render options. - Add Subsurface BSDF to your shader. - Check "Screen Space Subsurface Scattering" in the material panel options. This initial implementation has a few limitations: - only supports gaussian SSS. - Does not support principled shader. - The radius parameters is baked down to a number of samples and then put into an UBO. This means the radius input socket cannot be used. You need to tweak the default vector directly. - The "texture blur" is considered as always set to 1

Eevee: SSS: Add Christensen-Burley diffusion profile. This seems to be a correct implementation of the same diffusion profile as Cycles uses by default. There are a few bias though: - We consider _A_ the albedo to be 1 when evaluating _s_. - We use a factor of 0.6 when computing _d_ to match more or less cycles results. Note that doing per pixel jittering does bias the result even further (loss of energy).

Implement Uniformbuffer objects for nodetree parameters For users that means you can tweak shaders in the nodetree and things are way faster. This is a huge improvement, particularly in systems that have no shader cache. From the code perspective it means we are no longer re-compiling the shader every time a value is tweaked in the UI. We are using uniforms for those values. It would be slow to add that many uniforms for all the shaders. So instead we are using UBO (Uniform Buffer Objects). This fixes the main issue of T51467. However GWN_shaderinterface_create() still needs to be improvedi. When opening a .blend all shaders are compiled once, so optimizing it will bring a measurable impact. ======================================================================== NOTE: This breaks update of Cycles material upon nodetree nodes tweaking. It will be fixed separately by depsgraph, once tackling T51925 (Animated Eevee values slowdown). The idea is to make Depsgraph update more granular. The XXX TODO in rna_nodetree.c will be tackled at that time as well. ======================================================================== Reviewers: sergey, brecht, fclem Differential Revision: https://developer.blender.org/D2739

Eevee: Initial Separable Subsurface Scattering implementation. How to use: - Enable subsurface scattering in the render options. - Add Subsurface BSDF to your shader. - Check "Screen Space Subsurface Scattering" in the material panel options. This initial implementation has a few limitations: - only supports gaussian SSS. - Does not support principled shader. - The radius parameters is baked down to a number of samples and then put into an UBO. This means the radius input socket cannot be used. You need to tweak the default vector directly. - The "texture blur" is considered as always set to 1

OpenGL: Moving the GPU_pass_update_uniforms() call from GPU_material_bind_uniforms() to GPU_material_bind(). This way, material specific uniforms don't need to be resent when sending object specific uniforms. This saves uniform update calls in the BGE where one material is bound and multiple objects can be drawn. This doesn't offer much in the way of performance, but it cleans up our OpenGL usage a bit. One test scene went from 8k OpenGL calls to 4k with just this one change.

Merge of first part of changes from the apricot branch, especially the features that are needed to run the game. Compile tested with scons, make, but not cmake, that seems to have an issue not related to these changes. The changes include: * GLSL support in the viewport and game engine, enable in the game menu in textured draw mode. * Synced and merged part of the duplicated blender and gameengine/ gameplayer drawing code. * Further refactoring of game engine drawing code, especially mesh storage changed a lot. * Optimizations in game engine armatures to avoid recomputations. * A python function to get the framerate estimate in game. * An option take object color into account in materials. * An option to restrict shadow casters to a lamp's layers. * Increase from 10 to 18 texture slots for materials, lamps, word. An extra texture slot shows up once the last slot is used. * Memory limit for undo, not enabled by default yet because it needs the .B.blend to be changed. * Multiple undo for image painting. * An offset for dupligroups, so not all objects in a group have to be at the origin.

Blender Internal: Add "Lamp Data" shader node that allows shaders to acquire information such as light vector from specified Lamp. For now this provides the following outputs: - Color - Light Vector - Distance - Shadow - Visibility Factor Note: Color output is multiplied by the lamp energy. Multiplication of color*max(dot(light_vector,normal_vector),0)*shadow*visibility_factor produces the exact same result as the Lambert shader. Many thanks to Brecht for code review and discussion!

World background working on cycle nodes. This is added in the spirit of the general cycles GLSL system which is pretty much WIP still. This will only work on cycles at the moment but generating for blender internal is possible too of course though it will be done in a separate commit. This hasn't been tested with all and every node in cycles, but environment and regular textures with texture coordinates work. There is some difference between the way cycles treats some coordinates, which is in world space and the way GLSL treats them, which is in view space. We might want to explore and improve this further in the future. ...also </drumroll>

The only way to refresh the shaders is to change render engine. - Cleanup in GPUPass. - Add new temporary Node Compatibility type. Compatibility types should be removed in the future.

Implement Uniformbuffer objects for nodetree parameters For users that means you can tweak shaders in the nodetree and things are way faster. This is a huge improvement, particularly in systems that have no shader cache. From the code perspective it means we are no longer re-compiling the shader every time a value is tweaked in the UI. We are using uniforms for those values. It would be slow to add that many uniforms for all the shaders. So instead we are using UBO (Uniform Buffer Objects). This fixes the main issue of T51467. However GWN_shaderinterface_create() still needs to be improvedi. When opening a .blend all shaders are compiled once, so optimizing it will bring a measurable impact. ======================================================================== NOTE: This breaks update of Cycles material upon nodetree nodes tweaking. It will be fixed separately by depsgraph, once tackling T51925 (Animated Eevee values slowdown). The idea is to make Depsgraph update more granular. The XXX TODO in rna_nodetree.c will be tackled at that time as well. ======================================================================== Reviewers: sergey, brecht, fclem Differential Revision: https://developer.blender.org/D2739

Eevee: SSS: Add Christensen-Burley diffusion profile. This seems to be a correct implementation of the same diffusion profile as Cycles uses by default. There are a few bias though: - We consider _A_ the albedo to be 1 when evaluating _s_. - We use a factor of 0.6 when computing _d_ to match more or less cycles results. Note that doing per pixel jittering does bias the result even further (loss of energy).

Implement Uniformbuffer objects for nodetree parameters For users that means you can tweak shaders in the nodetree and things are way faster.

We are using uniforms for those values. It would be slow to add that many uniforms for all the shaders. So instead we are using UBO (Uniform Buffer Objects). This fixes the main issue of T51467. However GWN_shaderinterface_create() still needs to be improvedi. When opening a .blend all shaders are compiled once, so optimizing it will bring a measurable impact. ======================================================================== NOTE: This breaks update of Cycles material upon nodetree nodes tweaking. It will be fixed separately by depsgraph, once tackling T51925 (Animated Eevee values slowdown). The idea is to make Depsgraph update more granular.

TexFace to Material Settings big patch Summary: ======== The idea here is to move the texface options into the material panel. For images with the change please visit: http://code.blender.org/index.php/2011/09/bge-material-texface-changes 1 - Some of the legacy problems 2.49 and 2.5x has with the texface system: ========================================================================== 1.1) Shadow, Bilboard and Halo are mutual exclusive (in the code), yet you can select a face to be more than one mode. 1.2) Sort only works for blend Alpha yet it's an option regardless of the Transparency Blend you pick. 1.3) Shared doesn't affect anything in BGE. 1.4) ObColor only works for Text objects (old bitmap texts) when using Texture Face Materials. (not address yet, I so far ignored obcolor) 2 - Notes: ============ 2.1) Now "Use Face Textures" in material Option panel will work in Multitexture even if there is no texture channel. 2.2) In FaceTexture mode it will use TexFace all the time, even if you don't check the "Use Texture Face" option in the UI. It's a matter of decision, since the code for either way is there. I decided by the solution that makes the creation of a material fast - in this mode the user doesn't need to mess with textures or this "Use Texture Face" option at all. I'm not strong in my opinion here. But I think if we don't have this then what is the point of the Texture Face mode? 2.3) I kept references for tface only when we need the image, UV or the tiling setting. It should help later when/if we split the Image and UV layers from the tface struct (Campbell and Brecht proposal). 3 - Changes in a Nutshell: ========================== 3.1) "Texture Face" panel (in the Mesh/Object Data panel) no longer exists. Those settings are all part of the material properties, visible when Game Render is set. 3.2) "Texture Face" Shading mode (in the Render panel) is now called “Single Texture”, it needs a material for special settings (e.g. Billboard, Alpha Sort, …). 3.3) New options in the Material Panel * Shadeless option in the Material panel is now supported for all three Shading modes. * Physics is now toggleable, this is the old Collision option. * Two Side (on) is now called Back Culling (off). * Alpha Sort is one of the Alpha options, together (and mutually exclusive) to Alpha Blend, Alpha Clip, Add and Opaque (i.e. solid). * Shadow, Billboard and Halo are grouped in the “Face Orientation” property. * "Face Textures" and "Face Textures Alpha" (under Options) can be used for all but GLSL shading mode (to be supported in GLSL eventually). * The backend in the game engine is still the same as before. The only changes are in the interface and in the way you need to think your materials. The bottomline is: It’s no longer possible to share materials between faces that do not share the same game properties. 4 - Acknowledgment: ================== Mike Pan for the design discussions, and testing along the whole development process. Vitor Balbio for the first hands-on code with the interface changes. That helped me a lot to push me into work on that. Benoit Bolsee and Brecht van Lommel for patch review (* no one reviewed the whole patch, or the latest iteractions, so I still hold liability for any problems).

Color Management, Stage 2: Switch color pipeline to use OpenColorIO Replace old color pipeline which was supporting linear/sRGB color spaces only with OpenColorIO-based pipeline. This introduces two configurable color spaces: - Input color space for images and movie clips. This space is used to convert images/movies from color space in which file is saved to Blender's linear space (for float images, byte images are not internally converted, only input space is stored for such images and used later). This setting could be found in image/clip data block settings. - Display color space which defines space in which particular display is working. This settings could be found in scene's Color Management panel. When render result is being displayed on the screen, apart from converting image to display space, some additional conversions could happen. This conversions are: - View, which defines tone curve applying before display transformation. These are different ways to view the image on the same display device. For example it could be used to emulate film view on sRGB display. - Exposure affects on image exposure before tone map is applied. - Gamma is post-display gamma correction, could be used to match particular display gamma. - RGB curves are user-defined curves which are applying before display transformation, could be used for different purposes. All this settings by default are only applying on render result and does not affect on other images. If some particular image needs to be affected by this transformation, "View as Render" setting of image data block should be set to truth. Movie clips are always affected by all display transformations. This commit also introduces configurable color space in which sequencer is working. This setting could be found in scene's Color Management panel and it should be used if such stuff as grading needs to be done in color space different from sRGB (i.e. when Film view on sRGB display is use, using VD16 space as sequencer's internal space would make grading working in space which is close to the space using for display). Some technical notes: - Image buffer's float buffer is now always in linear space, even if it was created from 16bit byte images. - Space of byte buffer is stored in image buffer's rect_colorspace property. - Profile of image buffer was removed since it's not longer meaningful. - OpenGL and GLSL is supposed to always work in sRGB space. It is possible to support other spaces, but it's quite large project which isn't so much important. - Legacy Color Management option disabled is emulated by using None display. It could have some regressions, but there's no clear way to avoid them. - If OpenColorIO is disabled on build time, it should make blender behaving in the same way as previous release with color management enabled. More details could be found at this page (more details would be added soon): http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.64/Color_Management -- Thanks to Xavier Thomas, Lukas Toene for initial work on OpenColorIO integration and to Brecht van Lommel for some further development and code/ usecase review!

World space switch for BI nodes. At the moment light shading in Blender is produced in viewspace. Apparently, that's why shader nodes work with normals in camera space. But it is not convenient for artists. The more convenient approach is implemented in Cycles where normals are represented in world space. Blend4Web Team designed the engine keeping in mind shader parameters readability, so normals are interpreted in world space as well. And now our users have to use some tweaks, like empty node group with the name "Replace", which is replacing one input by another on the engine side (replacing working configuration in Blender Viewport by the configuration that has the same behavior in the engine). This patch adds the ability to switch to world space for normals and lamp vector in BI and Viewport. This patch is very important to us and we crave to see this patch in Blender 2.7 because it will significantly simplify Blend4Web material creation workflow. {F315547} {F315548} Reviewers: campbellbarton, brecht Reviewed By: brecht Subscribers: homyachetser, Evgeny_Rodygin, AlexKowel, yurikovelenov Differential Revision: https://developer.blender.org/D2046

Full Inverse-Quadratic-Equation Lamp Falloff This patch adds a new `falloff_type` ('Inverse Coefficients') for Lamps in Blender-Internal and GLSL. The current falloff modes use a formula like this inverse-square one: `I = E × (D^2 / (D^2 + Q × r^2))` While such a formula is simple for 3D-artists to use, it's algebraically cumbersome to work with. Game-designers authoring their own shaders could benefit much more by having direct control of falloff-coefficients: `I = E × (1.0 / (coefC + coefL × r + coefQ × r^2))` In this mode, the `distance` parameter is unused (except for 'Sphere' mode); instead relying on the designer to mathematically-model the falloff-behavior. The UI has been patched like so: {F153843} Reviewers: brecht, psy-fi Reviewed By: psy-fi Subscribers: brita_, antidote, campbellbarton, psy-fi Differential Revision: https://developer.blender.org/D1194

The changes include: * GLSL support in the viewport and game engine, enable in the game menu in textured draw mode. * Synced and merged part of the duplicated blender and gameengine/ gameplayer drawing code. * Further refactoring of game engine drawing code, especially mesh storage changed a lot. * Optimizations in game engine armatures to avoid recomputations. * A python function to get the framerate estimate in game. * An option take object color into account in materials. * An option to restrict shadow casters to a lamp's layers. * Increase from 10 to 18 texture slots for materials, lamps, word. An extra texture slot shows up once the last slot is used. * Memory limit for undo, not enabled by default yet because it needs the .B.blend to be changed. * Multiple undo for image painting. * An offset for dupligroups, so not all objects in a group have to be at the origin.

Merge of first part of changes from the apricot branch, especially the features that are needed to run the game. Compile tested with scons, make, but not cmake, that seems to have an issue not related to these changes. The changes include: * GLSL support in the viewport and game engine, enable in the game menu in textured draw mode. * Synced and merged part of the duplicated blender and gameengine/ gameplayer drawing code. * Further refactoring of game engine drawing code, especially mesh storage changed a lot. * Optimizations in game engine armatures to avoid recomputations. * A python function to get the framerate estimate in game. * An option take object color into account in materials. * An option to restrict shadow casters to a lamp's layers. * Increase from 10 to 18 texture slots for materials, lamps, word. An extra texture slot shows up once the last slot is used. * Memory limit for undo, not enabled by default yet because it needs the .B.blend to be changed. * Multiple undo for image painting. * An offset for dupligroups, so not all objects in a group have to be at the origin.

Threaded object update and EvaluationContext Summary: Made objects update happening from multiple threads. It is a task-based scheduling system which uses current dependency graph for spawning new tasks. This means threading happens on object level, but the system is flexible enough for higher granularity. Technical details: - Uses task scheduler which was recently committed to trunk (that one which Brecht ported from Cycles). - Added two utility functions to dependency graph: * DAG_threaded_update_begin, which is called to initialize threaded objects update. It will also schedule root DAG node to the queue, hence starting evaluation process. Initialization will calculate how much parents are to be evaluation before current DAG node can be scheduled. This value is used by task threads for faster detecting which nodes might be scheduled. * DAG_threaded_update_handle_node_updated which is called from task thread function when node was fully handled. This function decreases num_pending_parents of node children and schedules children with zero valency. As it might have become clear, task thread receives DAG nodes and decides which callback to call for it. Currently only BKE_object_handle_update is called for object nodes. In the future it'll call node->callback() from Ali's new DAG. - This required adding some workarounds to the render pipeline. Mainly to stop using get_object_dm() from modifiers' apply callback. Such a call was only a workaround for dependency graph glitch when rendering scene with, say, boolean modifiers before displaying this scene. Such change moves workaround from one place to another, so overall hackentropy remains the same. - Added paradigm of EvaluaitonContext. Currently it's more like just a more reliable replacement for G.is_rendering which fails in some circumstances. Future idea of this context is to also store all the local data needed for objects evaluation such as local time, Copy-on-Write data and so. There're two types of EvaluationContext: * Context used for viewport updated and owned by Main. In the future this context might be easily moved to Window or Screen to allo per-window/per-screen local time. * Context used by render engines to evaluate objects for render purposes. Render engine is an owner of this context. This context is passed to all object update routines.

2008-09-05 20:34:35 +00:00
Fix for image transparency backwards compatibility. Now the texture datablock has a Use Alpha option again. This makes the case where you enabled Premultiply on the image and disabled Use Alpha on the texture work again. That's mostly useful when you have a straight alpha image file which has no useful RGB colors in zero alpha regions (e.g. renders). Then sometimes you don't want to use the alpha for the texture stack mixing, but you still want to multiply it into the RGB channels to avoid a blocky transition into zero alpha regions. This also removes the version patch that copied image datablocks because it's not reliable and might be causing bug #34434. This does mean we are no longer backwards compatible for cases where two different texture datablocks with Use Alpha enabled and disabled where using the same image.

Image thread safe improvements This commit makes BKE_image_acquire_ibuf referencing result, which means once some area requested for image buffer, it'll be guaranteed this buffer wouldn't be freed by image signal. To de-reference buffer BKE_image_release_ibuf should now always be used. To make referencing working correct we can not rely on result of image_get_ibuf_threadsafe called outside from thread lock. This is so because we need to guarantee getting image buffer from list of loaded buffers and it's referencing happens atomic. Without lock here it is possible that between call of image_get_ibuf_threadsafe and referencing the buffer IMA_SIGNAL_FREE would be called. Image signal handling too is blocking now to prevent such a situation. Threads are locking by spinlock, which are faster than mutexes. There were some slowdown reports in the past about render slowdown when using OSX on Xeon CPU. It shouldn't happen with spin locks, but more tests on different hardware would be really welcome. So far can not see speed regressions on own computers. This commit also removes BKE_image_get_ibuf, because it was not so intuitive when get_ibuf and acquire_ibuf should be used. Thanks to Ton and Brecht for discussion/review :)

Bicubic bump map filtering. This commit introduces bicubic bump map capabilities for the viewport for OpenGL 3.0+ capable GPUs. To use the functionality change the bump mapping method to "best quality" Previous "best quality" setting becomes "medium quality" now. For non OpenGL 3.0 GPUs this becomes the same as "medium quality" Also: * added tooltip descriptions to the bump method settings. * modified the shader to ommit extraneous matrix multiplications for matrices already provided by OpenGL. Bicubic shader by Morten Mikkelsen. Thanks a lot! Oh...and FIRST!

Compile tested with scons, make, but not cmake, that seems to have an issue not related to these changes. The changes include: * GLSL support in the viewport and game engine, enable in the game menu in textured draw mode. * Synced and merged part of the duplicated blender and gameengine/ gameplayer drawing code. * Further refactoring of game engine drawing code, especially mesh storage changed a lot. * Optimizations in game engine armatures to avoid recomputations. * A python function to get the framerate estimate in game. * An option take object color into account in materials. * An option to restrict shadow casters to a lamp's layers. * Increase from 10 to 18 texture slots for materials, lamps, word. An extra texture slot shows up once the last slot is used. * Memory limit for undo, not enabled by default yet because it needs the .B.blend to be changed. * Multiple undo for image painting. * An offset for dupligroups, so not all objects in a group have to be at the origin.

Environment lighting for the GLSL mode Environment lighting (aka ambient) is a key component of any renderer. It's implemented like the Environment lighting of BI render for Approximate Gather mode. It support "Sky Color" and "White" Environment lighting modes. It would be great if the user could see actual lighting conditions right in the Blender viewport instead of waiting for the renderer to complete the final image, exporting for external renderer or for a game engine.

Compile tested with scons, make, but not cmake, that seems to have an issue not related to these changes. The changes include: * GLSL support in the viewport and game engine, enable in the game menu in textured draw mode. * Synced and merged part of the duplicated blender and gameengine/ gameplayer drawing code. * Further refactoring of game engine drawing code, especially mesh storage changed a lot. * Optimizations in game engine armatures to avoid recomputations. * A python function to get the framerate estimate in game. * An option take object color into account in materials. * An option to restrict shadow casters to a lamp's layers. * Increase from 10 to 18 texture slots for materials, lamps, word. An extra texture slot shows up once the last slot is used. * Memory limit for undo, not enabled by default yet because it needs the .B.blend to be changed. * Multiple undo for image painting. * An offset for dupligroups, so not all objects in a group have to be at the origin.

many functions in blender are not marked static but should be. most local modifier,GPU,ImBuf and Interface functions are now static. also fixed an error were the fluid modifier definition and the header didnt have the same number of args.

Fix #33371: blender freezing in material draw mode. When FBO failed in a particular way it could cause the opengl draw buffer to be set wrong, effectively disabling all opengl drawing. The FBO error was caused by cycles GLSL materials with no nodes that would still use blender internal materials, which caused issues with lamp shadow buffers FBO. This also fixes a GLSL refresh issue when switching render engines.

Matcap support in 3D Viewport. Full log is here: http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.66/Usability#Matcap_in_3D_viewport Implementation notes: - Matcaps are an extension of Solid draw mode, and don't show in other drawmodes. (It's mostly intended to aid modeling/sculpt) - By design, Matcaps are a UI feature, and only stored locally for the UI itself, and won't affect rendering or materials. - Currently a set of 16 (GPL licensed) Matcaps have been compiled into Blender. It doesn't take memory or cpu time, until you use it. - Brush Icons and Matcaps use same code now, and only get generated/allocated on actually using it (instead of on startup). - The current set might get new or different images still, based on user feedback. - Matcap images are 512x512 pixels, so each image takes 1 Mb memory. Unused matcaps get freed immediately. The Matcap icon previews (128x128 pixels) stay in memory. - Loading own matcap image files will be added later. That needs design and code work to get it stable and memory-friendly. - The GLSL code uses the ID PreviewImage for matcaps. I tested it using the existing Material previews, which has its limits... especially for textured previews the normal-mapped matcap won't look good.

Make matcaps suck less This commit does various changes for matcaps: One is taking advantage of drawing with pbvh (which would only happen with dyntopo previously) and drawing with partial redraw during sculpting. The second one is support for masks. To make this work in the special case of multires, which uses flat shading, I use the only available flat shaded builtins in OpenGL 2.0 which are color and secondary color. Abusing colors in that way is also essential for flat shading to work if we are to use pbvh draw in multires, since it is the color that is being interpolated flatly, not the normal (which can only interpolated smoothly). The pbvh drawing code for multires used last triangle element's normal to compute the shading which would only produce smooth results. This could change if we did the shading in the vertex shader for flat shaded primitives, but this is more complex and makes it harder to have one shader to rule the mole. Also increased the brightness of the default diffuse color for sculpting. This should be useful since artists like to tweak the lighting settings and it will give them the full dynamic range of the lights, but also it helps with correct brightness of sculpted matcaps.

/* some explanations here:
* matcap normal holds the normal remapped to the 0.0 - 1.0 range. To take advantage of flat shading, we abuse
* the built in secondary color of opengl. Color is just the regular color, which should include mask value too.
* This also needs flat shading so we use the primary opengl color built-in */

OpenSubdiv: Commit of OpenSubdiv integration into Blender This commit contains all the remained parts needed for initial integration of OpenSubdiv into Blender's subdivision surface code. Includes both GPU and CPU backends which works in the following way: - When SubSurf modifier is the last in the modifiers stack then GPU pipeline of OpenSubdiv is used, making viewport performance as fast as possible. This also requires graphscard with GLSL 1.5 support. If this requirement is not met, then no GPU pipeline is used at all. - If SubSurf is not a last modifier or if DerivesMesh is being evaluated for rendering then CPU limit evaluation API from OpenSubdiv is used. This only replaces the legacy evaluation code from CCGSubSurf_legacy, but keeps CCG structures exactly the same as they used to be for ages now. This integration is fully covered with ifdef and not enabled by default because there are several TODOs to be solved first: - Face varying data interpolation is not really cleanly implemented for GPU in OpenSubdiv 3.0. It is also not implemented for limit evaluation API. This basically means we'll have really hard time supporting UVs. - Limit evaluation only works with adaptivly subdivided meshes so far, which basically means all the points of CCG are pushed to the limit. This gives different result from old code. - There are some serious optimizations possible on the topology refiner creation, which would speed up initial OpenSubdiv mesh creation. - There are some hardcoded asumptions in the GPU and DerivedMesh areas which could be generalized. That's something where Antony and Campbell can help, making it so the code is structured in a way which is reusable by all planned viewport projects. - There are also some workarounds in the dependency graph to make sure OpenGL buffers are only freed from the main thread. Those who'll be wanting to make experiments with this code should grab dev branch (NOT master) from https://github.com/Nazg-Gul/OpenSubdiv/tree/dev There are some patches applied in there which we're working on on getting into upstream.

World background working on cycle nodes. This is added in the spirit of the general cycles GLSL system which is pretty much WIP still. This will only work on cycles at the moment but generating for blender internal is possible too of course though it will be done in a separate commit. This hasn't been tested with all and every node in cycles, but environment and regular textures with texture coordinates work. There is some difference between the way cycles treats some coordinates, which is in world space and the way GLSL treats them, which is in view space. We might want to explore and improve this further in the future. ...also </drumroll>

Fix compatibility flag for nodetree NODE_NEWER_SHADING was introduced in e868b459bb8e however it should have been added as a bitflag. BKE_scene_uses_blender_eevee() was used in gpu_shader_output() as a workaround for compatibility being poorly used. Anyways this fixes this situation. This is necessary for an upcoming patch, even though this is considered temporary - since the other NODE_*_SHADING values are legacy from Blender Internal drawing.

Implement Uniformbuffer objects for nodetree parameters For users that means you can tweak shaders in the nodetree and things are way faster. This is a huge improvement, particularly in systems that have no shader cache. From the code perspective it means we are no longer re-compiling the shader every time a value is tweaked in the UI. We are using uniforms for those values. It would be slow to add that many uniforms for all the shaders. So instead we are using UBO (Uniform Buffer Objects). This fixes the main issue of T51467. However GWN_shaderinterface_create() still needs to be improvedi. When opening a .blend all shaders are compiled once, so optimizing it will bring a measurable impact. ======================================================================== NOTE: This breaks update of Cycles material upon nodetree nodes tweaking. It will be fixed separately by depsgraph, once tackling T51925 (Animated Eevee values slowdown). The idea is to make Depsgraph update more granular. The XXX TODO in rna_nodetree.c will be tackled at that time as well. ======================================================================== Reviewers: sergey, brecht, fclem Differential Revision: https://developer.blender.org/D2739

OpenSubdiv: Commit of OpenSubdiv integration into Blender This commit contains all the remained parts needed for initial integration of OpenSubdiv into Blender's subdivision surface code. Includes both GPU and CPU backends which works in the following way: - When SubSurf modifier is the last in the modifiers stack then GPU pipeline of OpenSubdiv is used, making viewport performance as fast as possible. This also requires graphscard with GLSL 1.5 support. If this requirement is not met, then no GPU pipeline is used at all. - If SubSurf is not a last modifier or if DerivesMesh is being evaluated for rendering then CPU limit evaluation API from OpenSubdiv is used. This only replaces the legacy evaluation code from CCGSubSurf_legacy, but keeps CCG structures exactly the same as they used to be for ages now. This integration is fully covered with ifdef and not enabled by default because there are several TODOs to be solved first: - Face varying data interpolation is not really cleanly implemented for GPU in OpenSubdiv 3.0. It is also not implemented for limit evaluation API. This basically means we'll have really hard time supporting UVs. - Limit evaluation only works with adaptivly subdivided meshes so far, which basically means all the points of CCG are pushed to the limit. This gives different result from old code. - There are some serious optimizations possible on the topology refiner creation, which would speed up initial OpenSubdiv mesh creation. - There are some hardcoded asumptions in the GPU and DerivedMesh areas which could be generalized. That's something where Antony and Campbell can help, making it so the code is structured in a way which is reusable by all planned viewport projects. - There are also some workarounds in the dependency graph to make sure OpenGL buffers are only freed from the main thread. Those who'll be wanting to make experiments with this code should grab dev branch (NOT master) from https://github.com/Nazg-Gul/OpenSubdiv/tree/dev There are some patches applied in there which we're working on on getting into upstream.

Compile tested with scons, make, but not cmake, that seems to have an issue not related to these changes. The changes include: * GLSL support in the viewport and game engine, enable in the game menu in textured draw mode. * Synced and merged part of the duplicated blender and gameengine/ gameplayer drawing code. * Further refactoring of game engine drawing code, especially mesh storage changed a lot. * Optimizations in game engine armatures to avoid recomputations. * A python function to get the framerate estimate in game. * An option take object color into account in materials. * An option to restrict shadow casters to a lamp's layers. * Increase from 10 to 18 texture slots for materials, lamps, word. An extra texture slot shows up once the last slot is used. * Memory limit for undo, not enabled by default yet because it needs the .B.blend to be changed. * Multiple undo for image painting. * An offset for dupligroups, so not all objects in a group have to be at the origin.

OpenSubdiv: Commit of OpenSubdiv integration into Blender This commit contains all the remained parts needed for initial integration of OpenSubdiv into Blender's subdivision surface code.

This also requires graphscard with GLSL 1.5 support. If this requirement is not met, then no GPU pipeline is used at all. - If SubSurf is not a last modifier or if DerivesMesh is being evaluated for rendering then CPU limit evaluation API from OpenSubdiv is used.

Texturing: texture and 3d view draw type changes, these should only have any effect for a render engine using new shading nodes. In short: * No longer uses images assigned to faces in the uv layer, rather the active image texture node is what is edited/painted/drawn. * Textured draw type now shows the active image texture node, with solid lighting. * Material draw mode shows GLSL shader of a simplified material node tree, using solid lighting. * Textures for modifiers, brushes, etc, are now available from a dropdown in the texture tab in the properties editor.

We might want to explore and improve this further in the future. ...also </drumroll>

Merge of first part of changes from the apricot branch, especially the features that are needed to run the game. Compile tested with scons, make, but not cmake, that seems to have an issue not related to these changes. The changes include: * GLSL support in the viewport and game engine, enable in the game menu in textured draw mode. * Synced and merged part of the duplicated blender and gameengine/ gameplayer drawing code. * Further refactoring of game engine drawing code, especially mesh storage changed a lot. * Optimizations in game engine armatures to avoid recomputations. * A python function to get the framerate estimate in game. * An option take object color into account in materials. * An option to restrict shadow casters to a lamp's layers. * Increase from 10 to 18 texture slots for materials, lamps, word. An extra texture slot shows up once the last slot is used. * Memory limit for undo, not enabled by default yet because it needs the .B.blend to be changed. * Multiple undo for image painting. * An offset for dupligroups, so not all objects in a group have to be at the origin.

Blender Internal: Add "Lamp Data" shader node that allows shaders to acquire information such as light vector from specified Lamp. For now this provides the following outputs: - Color - Light Vector - Distance - Shadow - Visibility Factor Note: Color output is multiplied by the lamp energy. Multiplication of color*max(dot(light_vector,normal_vector),0)*shadow*visibility_factor produces the exact same result as the Lambert shader. Many thanks to Brecht for code review and discussion!

OpenSubdiv: Commit of OpenSubdiv integration into Blender This commit contains all the remained parts needed for initial integration of OpenSubdiv into Blender's subdivision surface code. Includes both GPU and CPU backends which works in the following way: - When SubSurf modifier is the last in the modifiers stack then GPU pipeline of OpenSubdiv is used, making viewport performance as fast as possible. This also requires graphscard with GLSL 1.5 support. If this requirement is not met, then no GPU pipeline is used at all. - If SubSurf is not a last modifier or if DerivesMesh is being evaluated for rendering then CPU limit evaluation API from OpenSubdiv is used. This only replaces the legacy evaluation code from CCGSubSurf_legacy, but keeps CCG structures exactly the same as they used to be for ages now. This integration is fully covered with ifdef and not enabled by default because there are several TODOs to be solved first: - Face varying data interpolation is not really cleanly implemented for GPU in OpenSubdiv 3.0. It is also not implemented for limit evaluation API. This basically means we'll have really hard time supporting UVs. - Limit evaluation only works with adaptivly subdivided meshes so far, which basically means all the points of CCG are pushed to the limit. This gives different result from old code. - There are some serious optimizations possible on the topology refiner creation, which would speed up initial OpenSubdiv mesh creation. - There are some hardcoded asumptions in the GPU and DerivedMesh areas which could be generalized. That's something where Antony and Campbell can help, making it so the code is structured in a way which is reusable by all planned viewport projects. - There are also some workarounds in the dependency graph to make sure OpenGL buffers are only freed from the main thread. Those who'll be wanting to make experiments with this code should grab dev branch (NOT master) from https://github.com/Nazg-Gul/OpenSubdiv/tree/dev There are some patches applied in there which we're working on on getting into upstream.
