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.

GPU: add gpu python module with export_shader() function to export GLSL shader. shader = gpu.export_shader(scene,material) Returns the GLSL shader that blender generates to produce the visual effect of material in scene for the purpose of reusing the shader in an external engine. This function is meant to be used in a material exporter so that the GLSL shader can be exported entirely. The return value is a dictionary containing the shader source code and all associated data. The full documentation is under sphinx. Warning: there has been an API between the patch and this commit: uniform['lamp'] and uniform['image'] now return python reference to ID block instead of ID name as before. The X3D exporter that uses this function must be adapted.

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

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.

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>

Refactor to recent matcap built-ins to not use the built in system. Those variables would get declared on fragment shader level and since we use reserved opengl variables, some compilers would throw an error (NVIDIA allows, some ATI compilers may break). Instead, use a separate opengl built-in category especially for them. This works on NVIDIA, and will wait for tests of this commit from ATI users.

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).

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

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.

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.

Refactor to recent matcap built-ins to not use the built in system. Those variables would get declared on fragment shader level and since we use reserved opengl variables, some compilers would throw an error (NVIDIA allows, some ATI compilers may break). Instead, use a separate opengl built-in category especially for them. This works on NVIDIA, and will wait for tests of this commit from ATI users.

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 Translucency support. This adds the possibility to simulate things like red ears with strong backlight or material with high scattering distances. To enable it you need to turn on the "Subsurface Translucency" option in the "Options" tab of the Material Panel (and of course to have "regular" SSS enabled in both render settings and material options). Since the effect is adding another overhead I prefer to make it optional. But this is open to discussion. Be aware that the effect only works for direct lights (so no indirect/world lighting) that have shadowmaps, and is affected by the "softness" of the shadowmap and resolution. Technical notes: This is inspired by http://www.iryoku.com/translucency/ but goes a bit beyond that. We do not use a sum of gaussian to apply in regards to the object thickness but we precompute a 1D kernel texture. This texture stores the light transmited to a point at the back of an infinite slab of material of variying thickness. We make the assumption that the slab is perpendicular to the light so that no fresnel or diffusion term is taken into account. The light is considered constant. If the setup is similar to the one assume during the profile baking, the realtime render matches cycles reference. Due to these assumptions the computed transmitted light is in most cases too bright for curvy objects. Finally we jitter the shadow map sample per pixel so we can simulate dispersion inside the medium. Radius of the dispersion is in world space and derived by from the "soft" shadowmap parameter. Idea for this come from this presentation http://www.iryoku.com/stare-into-the-future (slide 164).

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

GPUMaterial *GPU_material_from_nodetree(
Remove Blender Internal and legacy viewport from Blender 2.8. Brecht authored this commit, but he gave me the honours to actually do it. Here it goes; Blender Internal. Bye bye, you did great! * Point density, voxel data, ocean, environment map textures were removed, as these only worked within BI rendering. Note that the ocean modifier and the Cycles point density shader node continue to work. * Dynamic paint using material shading was removed, as this only worked with BI. If we ever wanted to support this again probably it should go through the baking API. * GPU shader export through the Python API was removed. This only worked for the old BI GLSL shaders, which no longer exists. Doing something similar for Eevee would be significantly more complicated because it uses a lot of multiplass rendering and logic outside the shader, it's probably impractical. * Collada material import / export code is mostly gone, as it only worked for BI materials. We need to add Cycles / Eevee material support at some point. * The mesh noise operator was removed since it only worked with BI material texture slots. A displacement modifier can be used instead. * The delete texture paint slot operator was removed since it only worked for BI material texture slots. Could be added back with node support. * Not all legacy viewport features are supported in the new viewport, but their code was removed. If we need to bring anything back we can look at older git revisions. * There is some legacy viewport code that I could not remove yet, and some that I probably missed. * Shader node execution code was left mostly intact, even though it is not used anywhere now. We may eventually use this to replace the texture nodes with Cycles / Eevee shader nodes. * The Cycles Bake panel now includes settings for baking multires normal and displacement maps. The underlying code needs to be merged properly, and we plan to add back support for multires AO baking and add support to Cycles baking for features like vertex color, displacement, and other missing baking features. * This commit removes DNA and the Python API for BI material, lamp, world and scene settings. This breaks a lot of addons. * There is more DNA that can be removed or renamed, where Cycles or Eevee are reusing some old BI properties but the names are not really correct anymore. * Texture slots for materials, lamps and world were removed. They remain for brushes, particles and freestyle linestyles. * 'BLENDER_RENDER' remains in the COMPAT_ENGINES of UI panels. Cycles and other renderers use this to find all panels to show, minus a few panels that they have their own replacement for.

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.

unify include guard defines, __$FILENAME__ without the underscores these clogged up the namespace for autocompleation which was annoying.
