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.

Potential fix for T43987, ambient occlusion different between offscreen and on screen rendering. Aaaaah, the beauty of driver implementations of OpenGL! Turns out the problem here is that drivers calculate df/dy differently in some cases (probably because OpenGL counts y reverse to how the window system does, so drivers can get confused). Fixed this for the ATI case based on info we have so far, there's also the Intel case which will be handled separately (missing info on Intel's renderer string etc). Unfortunately we can't really fix this for the general case so we'll have to haldle cases as they come in our tracker and by adding silly string comparisons in our GPU initialization module <sigh>.

Debug GPU functionality from soc-viewport_fx by Jason Wilkins patch number D706 with changes: - WITH_GPU_DEBUG just creates a debug context (and enables the debug messaging system functions) but leaves the checks we had intact. Old patch added the debug functionality only if we had the flag on to save some performance. Rationale here is that we might not want to recompile blender just to get the extra information, and having users start blender with a -d flag to get the extra information is also useful for bug reports. Those checks already existed and most expensive ones are hidden behind a debug mode check so performance should not be that bad. - Did some cleanup of existing functionality: When things go wrong blender side, just print the error, don't check for GL errors first. - Did not port changes needed for GLES to regular glew.h - Got rid of duplicate or very similar new functionality. Generally, code is more moving things around/cleanup and should work exactly as before apart from the debug context, so it's safe to add even now. It also provides a nice substitute function for glu error descriptions

Viewport compositing - first code This commit introduces a few ready made effects for the 3D viewport and OpenGL rendering. Included effects are Depth of Field, accessible from camera view and screen space ambient occlusion. Those effects can be turned on and tweaked from the shading panel in the 3D viewport. Off screen rendering will use the settings of the current camera. WIP documentation can be found here: http://wiki.blender.org/index.php/User:Psy-Fi/Framebuffer_Post-processing

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.

Another attempt for T40981, clipping border does not work with GLSL on ATIs. This is actually a test to see if this can be enabled on ATI cards. According to various sources, newer ATI cards supporting GLSL 3.0 support gl_ClippingDistance in shaders, which is the forward compatible way to do custom clipping. This fix will bind 6 additional varying variables on ATIs, which may lead to some shaders not compiling due to limiting out of those variables, or to performance degradation. Also I do not have an ATI handy to test. Having those in mind, this commit may well be reverted later. Clipping planes are usually 4 (6 is for cube clipping), but making shaders depend on viewport state is really bad, and would lead to recompilation, so I took the worst case here to avoid that. Hopefully driver does some optimization there.

Depth of field high quality: A new checkbox "High quality" is provided in camera settings to enable this. This creates a depth of field that is much closer to the rendered result and even supports aperture blades in the effect, but it's more expensive too. There are optimizations to do here since the technique is very fill rate heavy. People, be careful, this -can- lock up your screen if depth of field blurring is too extreme. Technical details: This uses geometry shaders + instancing and is an adaptation of techniques gathered from http://bartwronski.com/2014/04/07/bokeh-depth-of-field-going-insane- http://advances.realtimerendering.com/s2011/SousaSchulzKazyan%20- %20in%20Real-Time%20Rendering%20Course).ppt TODOs: * Support dithering to minimize banding. * Optimize fill rate in geometry shader.

Compositing works with X-Ray. Basically, before drawing X-Rays, we now bind a second depth buffer. After drawing XRays, we do an extra resolve pass where we overwrite the non-XRay depth buffer in pixels where the depth is not maximum (which means background pixel, since depth is cleared before drawing X-Ray objects). This ensures both scene and X-Rays keep their depth values and are ready for compositing. Well, the odd effect due to depth discontinuities can be expected, and X-Rays are a bit more expensive (extra buffer + resolve pass) but at least X-Rays won't invalidate depth values anymore. Whee!

Potential fix for T43987, ambient occlusion different between offscreen and on screen rendering. Aaaaah, the beauty of driver implementations of OpenGL! Turns out the problem here is that drivers calculate df/dy differently in some cases (probably because OpenGL counts y reverse to how the window system does, so drivers can get confused). Fixed this for the ATI case based on info we have so far, there's also the Intel case which will be handled separately (missing info on Intel's renderer string etc). Unfortunately we can't really fix this for the general case so we'll have to haldle cases as they come in our tracker and by adding silly string comparisons in our GPU initialization module <sigh>.

WM Draw Methods now has a new option Automatic (default). This will set the draw method to triple buffer or overlap depending on the configuration. Ideally I could get all cases working well with triple buffer but it's hard in practice. At the moment there are two cases that use overlap instead: * opensource ATI drives on linux * windows software renderer Also added a utility function to check GPU device/os/driver.

OpenGL: implemenation of fixed function lighting as per pixel GLSL shaders. The code is still unused, but the intention is to use this to solve the double sided lighting problem on NVidia, and to make the materials work on OpenGL ES 2.0 eventually. The code works and matches the fixed function lighting pretty much exactly, but still needs optimizations. The actual integration in object draw will be committed later when more fixing & testing, there's lots of different combinations and unclear OpenGL state here.

Fix T40498 invalid textures flickering. Issue here is most likely sampler uniforms and textures not being updated properly when zero binding is created. Solution for now is to allow zero binding but when this happens use sexy pink invalid texture instead :p.

Potential fix for T43987, ambient occlusion different between offscreen and on screen rendering. Aaaaah, the beauty of driver implementations of OpenGL! Turns out the problem here is that drivers calculate df/dy differently in some cases (probably because OpenGL counts y reverse to how the window system does, so drivers can get confused). Fixed this for the ATI case based on info we have so far, there's also the Intel case which will be handled separately (missing info on Intel's renderer string etc). Unfortunately we can't really fix this for the general case so we'll have to haldle cases as they come in our tracker and by adding silly string comparisons in our GPU initialization module <sigh>.

This creates a depth of field that is much closer to the rendered result and even supports aperture blades in the effect, but it's more expensive too.

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.

This can make viewing slow (it's an extra O^3 operation), but this will probably help us render the tornado in 3D viewport in gooseberry and still actually see something - despite the rendering taking longer.

Compile tested with scons, make, but not cmake, that seems to have an issue not related to these changes.

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.

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.

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.

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.

Debug GPU functionality from soc-viewport_fx by Jason Wilkins patch number D706 with changes: - WITH_GPU_DEBUG just creates a debug context (and enables the debug messaging system functions) but leaves the checks we had intact. Old patch added the debug functionality only if we had the flag on to save some performance. Rationale here is that we might not want to recompile blender just to get the extra information, and having users start blender with a -d flag to get the extra information is also useful for bug reports. Those checks already existed and most expensive ones are hidden behind a debug mode check so performance should not be that bad. - Did some cleanup of existing functionality: When things go wrong blender side, just print the error, don't check for GL errors first. - Did not port changes needed for GLES to regular glew.h - Got rid of duplicate or very similar new functionality. Generally, code is more moving things around/cleanup and should work exactly as before apart from the debug context, so it's safe to add even now. It also provides a nice substitute function for glu error descriptions

Depth of field high quality: A new checkbox "High quality" is provided in camera settings to enable this. This creates a depth of field that is much closer to the rendered result and even supports aperture blades in the effect, but it's more expensive too. There are optimizations to do here since the technique is very fill rate heavy. People, be careful, this -can- lock up your screen if depth of field blurring is too extreme. Technical details: This uses geometry shaders + instancing and is an adaptation of techniques gathered from http://bartwronski.com/2014/04/07/bokeh-depth-of-field-going-insane- http://advances.realtimerendering.com/s2011/SousaSchulzKazyan%20- %20in%20Real-Time%20Rendering%20Course).ppt TODOs: * Support dithering to minimize banding. * Optimize fill rate in geometry shader.

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.

Debug GPU functionality from soc-viewport_fx by Jason Wilkins patch number D706 with changes: - WITH_GPU_DEBUG just creates a debug context (and enables the debug messaging system functions) but leaves the checks we had intact. Old patch added the debug functionality only if we had the flag on to save some performance. Rationale here is that we might not want to recompile blender just to get the extra information, and having users start blender with a -d flag to get the extra information is also useful for bug reports. Those checks already existed and most expensive ones are hidden behind a debug mode check so performance should not be that bad. - Did some cleanup of existing functionality: When things go wrong blender side, just print the error, don't check for GL errors first. - Did not port changes needed for GLES to regular glew.h - Got rid of duplicate or very similar new functionality. Generally, code is more moving things around/cleanup and should work exactly as before apart from the debug context, so it's safe to add even now. It also provides a nice substitute function for glu error descriptions

Those checks already existed and most expensive ones are hidden behind a debug mode check so performance should not be that bad. - Did some cleanup of existing functionality: When things go wrong blender side, just print the error, don't check for GL errors first. - Did not port changes needed for GLES to regular glew.h - Got rid of duplicate or very similar new functionality. Generally, code is more moving things around/cleanup and should work exactly as before apart from the debug context, so it's safe to add even now. It also provides a nice substitute function for glu error descriptions

Viewport compositing - first code This commit introduces a few ready made effects for the 3D viewport and OpenGL rendering. Included effects are Depth of Field, accessible from camera view and screen space ambient occlusion. Those effects can be turned on and tweaked from the shading panel in the 3D viewport. Off screen rendering will use the settings of the current camera. WIP documentation can be found here: http://wiki.blender.org/index.php/User:Psy-Fi/Framebuffer_Post-processing

Depth of field high quality: A new checkbox "High quality" is provided in camera settings to enable this. This creates a depth of field that is much closer to the rendered result and even supports aperture blades in the effect, but it's more expensive too. There are optimizations to do here since the technique is very fill rate heavy. People, be careful, this -can- lock up your screen if depth of field blurring is too extreme. Technical details: This uses geometry shaders + instancing and is an adaptation of techniques gathered from http://bartwronski.com/2014/04/07/bokeh-depth-of-field-going-insane- http://advances.realtimerendering.com/s2011/SousaSchulzKazyan%20- %20in%20Real-Time%20Rendering%20Course).ppt TODOs: * Support dithering to minimize banding. * Optimize fill rate in geometry shader.

Debug GPU functionality from soc-viewport_fx by Jason Wilkins patch number D706 with changes: - WITH_GPU_DEBUG just creates a debug context (and enables the debug messaging system functions) but leaves the checks we had intact. Old patch added the debug functionality only if we had the flag on to save some performance. Rationale here is that we might not want to recompile blender just to get the extra information, and having users start blender with a -d flag to get the extra information is also useful for bug reports. Those checks already existed and most expensive ones are hidden behind a debug mode check so performance should not be that bad. - Did some cleanup of existing functionality: When things go wrong blender side, just print the error, don't check for GL errors first. - Did not port changes needed for GLES to regular glew.h - Got rid of duplicate or very similar new functionality.

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.

GPUFramebuffer API cleanup: * read buffers are set at texture binding time * change naming when setting a texture as framebuffer * add function to set slot of framebuffer as current target instead of texture. * Binding a buffer reuses the dimensions of the texture at bind time (can use viewport to set to arbitrary range later) * Removed offscreen buffer width/height, use the generated texture dimensions instead. Those were supposed to be checked to see if generated texture had the requested size but were never actually changed to the texture dimensions (and it's redundant to store twice).

OpenGL: implemenation of fixed function lighting as per pixel GLSL shaders. The code is still unused, but the intention is to use this to solve the double sided lighting problem on NVidia, and to make the materials work on OpenGL ES 2.0 eventually. The code works and matches the fixed function lighting pretty much exactly, but still needs optimizations. The actual integration in object draw will be committed later when more fixing & testing, there's lots of different combinations and unclear OpenGL state here.

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 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.

Another attempt for T40981, clipping border does not work with GLSL on ATIs. This is actually a test to see if this can be enabled on ATI cards. According to various sources, newer ATI cards supporting GLSL 3.0 support gl_ClippingDistance in shaders, which is the forward compatible way to do custom clipping. This fix will bind 6 additional varying variables on ATIs, which may lead to some shaders not compiling due to limiting out of those variables, or to performance degradation. Also I do not have an ATI handy to test. Having those in mind, this commit may well be reverted later. Clipping planes are usually 4 (6 is for cube clipping), but making shaders depend on viewport state is really bad, and would lead to recompilation, so I took the worst case here to avoid that. Hopefully driver does some optimization there.

Another attempt for T40981, clipping border does not work with GLSL on ATIs. This is actually a test to see if this can be enabled on ATI cards. According to various sources, newer ATI cards supporting GLSL 3.0 support gl_ClippingDistance in shaders, which is the forward compatible way to do custom clipping. This fix will bind 6 additional varying variables on ATIs, which may lead to some shaders not compiling due to limiting out of those variables, or to performance degradation. Also I do not have an ATI handy to test. Having those in mind, this commit may well be reverted later. Clipping planes are usually 4 (6 is for cube clipping), but making shaders depend on viewport state is really bad, and would lead to recompilation, so I took the worst case here to avoid that. Hopefully driver does some optimization there.

Fix T31546 fragment program gets created every frame That was really crappy indeed. Now we have a separate API for low level OpenGL programs, plus a nice interface for GPU, also removes some GL calls from main code as a plus :) The source for the programs is also moved to nice external .glsl files (not sure which extension convention GPU assemply uses)

Fix T46128: High Quality DoF broken The issue was caused by some special tricks needed to compile OpenSubdiv shader which was using stupid check whether geometry shader is used or not. Now made it more explicit call whether special OpenSubdiv trickery is needed or not. Its not ideal solution, but it's not really easy to do a proper solution for this, because while we can do half of the work with if-defs in the shader code but we'll still need to somewhat define layout of the input blocks which isn't really doable with current shader version we're using.

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.

This fix will bind 6 additional varying variables on ATIs, which may lead to some shaders not compiling due to limiting out of those variables, or to performance degradation. Also I do not have an ATI handy to test. Having those in mind, this commit may well be reverted later. Clipping planes are usually 4 (6 is for cube clipping), but making shaders depend on viewport state is really bad, and would lead to recompilation, so I took the worst case here to avoid that. Hopefully driver does some optimization there.

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.

Depth of field high quality: A new checkbox "High quality" is provided in camera settings to enable this. This creates a depth of field that is much closer to the rendered result and even supports aperture blades in the effect, but it's more expensive too. There are optimizations to do here since the technique is very fill rate heavy. People, be careful, this -can- lock up your screen if depth of field blurring is too extreme.

Fix high quality depth of field on the Mac. Quite a few things wrong here: * Mac did not support EXT_draw_instanced, only ARB_draw_instanced * Draw instanced did not work unless data came from vertex buffer, which is second time we see weird things with vertex arrays in mac * There were a few stupid mistakes by me as well, such as binding to uniform locations for the wrong shaders (it's a wonder it ever worked :p)

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.

Workaround for an Nvidia driver bug on 32 bit linux (maybe windows too). I reversed the order of attaching shader objects for linking to solve an issue in the driver before, but now it appears it needs to be the other way around again? I don't know if these are the same cards that now want it different again due to changes in the glsl code, but I found another workaround for the first bug in a forum post (leaving out parameter names in the declarations), so with some luck both cases work? http://developer.nvidia.com/forums/index.php?showtopic=596

Fix T41596 GLSL error on ATIs after clipping workaround commit. This was a little difficult to track down, basically it was a missing escape sequence that only manifested itself when GPU did not support bicubic filtering. Extra: * Fix memory leaks when an error occurs in shader compilation * Display full shader when a compilation error occurs. Makes it easier to diagnose if problem is caused by a syntax or compatibility error.

Debug GPU functionality from soc-viewport_fx by Jason Wilkins patch number D706 with changes: - WITH_GPU_DEBUG just creates a debug context (and enables the debug messaging system functions) but leaves the checks we had intact. Old patch added the debug functionality only if we had the flag on to save some performance. Rationale here is that we might not want to recompile blender just to get the extra information, and having users start blender with a -d flag to get the extra information is also useful for bug reports. Those checks already existed and most expensive ones are hidden behind a debug mode check so performance should not be that bad. - Did some cleanup of existing functionality: When things go wrong blender side, just print the error, don't check for GL errors first. - Did not port changes needed for GLES to regular glew.h - Got rid of duplicate or very similar new functionality. Generally, code is more moving things around/cleanup and should work exactly as before apart from the debug context, so it's safe to add even now. It also provides a nice substitute function for glu error descriptions

Debug GPU functionality from soc-viewport_fx by Jason Wilkins patch number D706 with changes: - WITH_GPU_DEBUG just creates a debug context (and enables the debug messaging system functions) but leaves the checks we had intact. Old patch added the debug functionality only if we had the flag on to save some performance. Rationale here is that we might not want to recompile blender just to get the extra information, and having users start blender with a -d flag to get the extra information is also useful for bug reports. Those checks already existed and most expensive ones are hidden behind a debug mode check so performance should not be that bad. - Did some cleanup of existing functionality: When things go wrong blender side, just print the error, don't check for GL errors first. - Did not port changes needed for GLES to regular glew.h - Got rid of duplicate or very similar new functionality. Generally, code is more moving things around/cleanup and should work exactly as before apart from the debug context, so it's safe to add even now. It also provides a nice substitute function for glu error descriptions

Viewport compositing - first code This commit introduces a few ready made effects for the 3D viewport and OpenGL rendering. Included effects are Depth of Field, accessible from camera view and screen space ambient occlusion. Those effects can be turned on and tweaked from the shading panel in the 3D viewport. Off screen rendering will use the settings of the current camera. WIP documentation can be found here: http://wiki.blender.org/index.php/User:Psy-Fi/Framebuffer_Post-processing

Attempt to fix T45718, crash when enabling GLSL mode with UV layers. I can't reproduce issue here but crash is most likely caused by passing a NULL pointer to glUniform2fv. This is caused by OpenSubdiv changes to the codegen module, which pass mtex layers to the uniform system even when not needed. Since Sergey is demoing OpenSubdiv in a few days, I'll go with the easy fix for now which is just checking for NULL pointer, but this needs to be fixed properly at some point.

Depth of field high quality: A new checkbox "High quality" is provided in camera settings to enable this. This creates a depth of field that is much closer to the rendered result and even supports aperture blades in the effect, but it's more expensive too. There are optimizations to do here since the technique is very fill rate heavy. People, be careful, this -can- lock up your screen if depth of field blurring is too extreme. Technical details: This uses geometry shaders + instancing and is an adaptation of techniques gathered from http://bartwronski.com/2014/04/07/bokeh-depth-of-field-going-insane- http://advances.realtimerendering.com/s2011/SousaSchulzKazyan%20- %20in%20Real-Time%20Rendering%20Course).ppt TODOs: * Support dithering to minimize banding. * Optimize fill rate in geometry shader.

OpenGL: implemenation of fixed function lighting as per pixel GLSL shaders. The code is still unused, but the intention is to use this to solve the double sided lighting problem on NVidia, and to make the materials work on OpenGL ES 2.0 eventually. The code works and matches the fixed function lighting pretty much exactly, but still needs optimizations. The actual integration in object draw will be committed later when more fixing & testing, there's lots of different combinations and unclear OpenGL state here.

Rationale here is that we might not want to recompile blender just to get the extra information, and having users start blender with a -d flag to get the extra information is also useful for bug reports. Those checks already existed and most expensive ones are hidden behind a debug mode check so performance should not be that bad. - Did some cleanup of existing functionality: When things go wrong blender side, just print the error, don't check for GL errors first. - Did not port changes needed for GLES to regular glew.h - Got rid of duplicate or very similar new functionality. Generally, code is more moving things around/cleanup and should work exactly as before apart from the debug context, so it's safe to add even now. It also provides a nice substitute function for glu error descriptions

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.

Compositing works with X-Ray. Basically, before drawing X-Rays, we now bind a second depth buffer. After drawing XRays, we do an extra resolve pass where we overwrite the non-XRay depth buffer in pixels where the depth is not maximum (which means background pixel, since depth is cleared before drawing X-Ray objects). This ensures both scene and X-Rays keep their depth values and are ready for compositing. Well, the odd effect due to depth discontinuities can be expected, and X-Rays are a bit more expensive (extra buffer + resolve pass) but at least X-Rays won't invalidate depth values anymore. Whee!

Now we have a separate API for low level OpenGL programs, plus a nice interface for GPU, also removes some GL calls from main code as a plus :) The source for the programs is also moved to nice external .glsl files (not sure which extension convention GPU assemply uses)

Viewport compositing - first code This commit introduces a few ready made effects for the 3D viewport and OpenGL rendering. Included effects are Depth of Field, accessible from camera view and screen space ambient occlusion. Those effects can be turned on and tweaked from the shading panel in the 3D viewport. Off screen rendering will use the settings of the current camera. WIP documentation can be found here: http://wiki.blender.org/index.php/User:Psy-Fi/Framebuffer_Post-processing

Add debug option --debug-gpumem to show GPU memory used in status bar. Only used in ATIs and NVIDIAs. Used extensions are: https://www.opengl.org/registry/specs/ATI/meminfo.txt http://developer.download.nvidia.com/opengl/specs/ If you read the documentation, the numbers are not supposed to be exact and also depend on the time when the call is made. The numbers can also change quite quickly. It's only meant to give a rough measure of what is going on.

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.
