2016-02-07Fix T47349: incorrect Cycles fresnel and layer weight with GLSL materials.Brecht Van Lommel
Patch by Ralf Hölzemer.

D1756 by @youle, uses existing texture mapping option.
2016-02-02Fix T47207: Material shading incorrectly handles colorramp nodeSergey Sharybin
The issue was introduced by a fix for T44713 which only made GLSL consistent with Cycles. Now we do have conditional averaging or proper luma weighting based on whether we're new old old shading system. Not totally ideal but should work for until we re-design viewport possibly breaking how Blender Internal does implicit conversion.

This patch supports "Image or Movie" and "Environment map" types of world texture for the viewport. It supports: - "View", "AngMap" and "Equirectangular" types of mapping. - Different types of texture blending (according to BI world render). - Same color blending as when it lacked textures (but render via glsl). {F207734} {F207735} Example: {F275180} Original author: @valentin_b4w Regards, Alexander (Blend4Web Team).

2016-01-22OpenGL: fewer state changes for wireframe PBVHMike Erwin
Wireframe drawing doesn’t use the following GL state, so don’t update these: - ShadeModel - NormalPointer - ColorPointer Normal & color data are still uploaded as part of the interleaved VBO, but those attributes are disabled for wireframe.

2016-01-16OpenGL: fixes related to GL_POINTSMike Erwin
I put all usage of GL_POINTS under the microscope. Fixed problems & optimized a couple of spots. - reduce calls to glPointSize by about 50% - draw selected & unselected vertices together for UV editor & EditMesh - draw initial gpencil stroke point the proper size - a few other smaller fixes New policy: each GL_POINTS draw call needs to set its desired point size. This eliminates half our calls to glPointSize (setting it back to its 1.0 default after every draw).
2016-01-10OpenGL Smoke: fix color issue, and clarify meaning of variables in the shader.Brecht Van Lommel
2016-01-10OpenGL: port smoke drawing code to GLSL.Kévin Dietrich
Beside the obvious ARB -> GLSL change, the texture slicing algorithm had to be rewritten. Although this new algorithm has the same behaviour as the old one (view aligned slicing), it works with an arbitrary number of slices (which could eventually be set by the user), which means we can preallocate the buffer. The previous algorithm would slice from the begining to the end of the volume's bbox, and draw the slices as it generates them. Also support for ARB program was removed. Patch by myself, with some minor fixes by Brecht. Reviewers: brecht, #opengl_gfx Differential Revision: https://developer.blender.org/D1694

ARB_framebuffer_object works just like GL 3+ and is the preferred method. Fall back to older EXT_framebuffer_object if necessary.

Removed reference to GL 1.x since we no longer support that. ES is likely in our future though!
2016-01-07Cycles: Refactor how we pass bounce info to light path node.Thomas Dinges
This commit changes the way how we pass bounce information to the Light Path node. Instead of manualy copying the bounces into ShaderData, we now directly pass PathState. This reduces the arguments that we need to pass around and also makes it easier to extend the feature. This commit also exposes the Transmission Bounce Depth to the Light Path node. It works similar to the Transparent Depth Output: Replace a Transmission lightpath after X bounces with another shader, e.g a Diffuse one. This can be used to avoid black surfaces, due to low amount of max bounces. Reviewed by Sergey and Brecht, thanks for some hlp with this. I tested compilation and usage on CPU (SVM and OSL), CUDA, OpenCL Split and Mega kernel. Hopefully this covers all devices. :)
2016-01-04Remove SCons building systemSergey Sharybin
While SCons building system was serving us really good for ages it's no longer having much attention by the developers and started to become quite a difficult task to maintain. What's even worse -- there started to be quite serious divergence between SCons and CMake which was only accumulating over the releases now. The fact that none of the active developers are really using SCons and that our main studio is also using CMake spotting bugs in the SCons builds became quite a difficult task and we aren't always spotting them in time. Meanwhile CMake became really mature building system which is available on every platform we support and arguably it's also easier and more robust to use. This commit includes: - Removal of actual SCons building system - Removal of SCons git submodule - Removal of documentation which is stored in the sources and covers SCons - Tweaks to the buildbot master to stop using SCons submodule (this change requires deploying to the server) - Tweaks to the install dependencies script to skip installing or mentioning SCons building system - Tweaks to various helper scripts to avoid mention of SCons folders/files as well Reviewers: mont29, dingto, dfelinto, lukastoenne, lukasstockner97, brecht, Severin, merwin, aligorith, psy-fi, campbellbarton, juicyfruit Reviewed By: campbellbarton, juicyfruit Differential Revision: https://developer.blender.org/D1680
2016-01-04OpenGL: GPU_legacy_support workaround for nVidiaMike Erwin
nVidia Linux driver reports GL_CONTEXT_PROFILE_MASK = 0, which is a bug. In that case check for the ARB_compatibility extension. Non-buggy drivers will continue to use GL_CONTEXT_COMPATIBILITY_PROFILE_BIT. Thx to Dr Hackerman for reporting.

2015-12-08OpenGL: use extension form of FBOsMike Erwin
FBOs are a GL 3.0 feature but enjoy nearly universal support via extensions. The newer ARB extension brings these features to GL 2.1 without needing an ARB suffix. The older EXT extensions *do* use a suffix. Since we don’t know which is used until runtime, I added the suffix to all functions & enums. Also updated the check to look for the FBO feature set instead of the specific EXT extension.
2015-12-08OpenGL: use sized texture internal formatsMike Erwin
Maybe this is pedantic but I read it’s best to explicitly set the desired component size. Also append “_ARB” to float texture formats since those need an extension in GL 2.1.

2015-12-07OpenGL: new GPU_legacy_support() functionMike Erwin
Is current context compatible with legacy GL (version 2.1)? My earlier approach -- checking for GLEW_ARB_compatibility -- was not enough. This should always return true if we set our GL context up properly. It will return false when we switch to core profile.
