2014-03-08geom-outlining-150: Use a vbo.Fabian Bieler1-7/+18
Use a vbo for vertex data instead of client-side arrays. Also bind a vertex array object. This is necessary for the switch to a core profile context. Signed-off-by: Fabian Bieler <fabianbieler@fastmail.fm> Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>

2014-03-08glsl/gsraytrace: Use core geometry shaders.Fabian Bieler1-15/+9
V2: Don't remove ShaderSupported() test. It sets up some function pointers for the CompileShader framework. Signed-off-by: Fabian Bieler <fabianbieler@fastmail.fm> Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>
2014-03-08glsl/gsraytrace: Use GLSL 1.5 instead of 1.2.Fabian Bieler1-26/+32
This commit prepares the transition from extension to core geometry shaders. (Core geometry shaders require GLSL version 1.5 or later.) This includes using generic vertex attributes instead of built-ins. Signed-off-by: Fabian Bieler <fabianbieler@fastmail.fm> Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>
2014-03-08glsl/gsraytrace: Use core GL3.0 transform feedbackFabian Bieler1-41/+31
NV_transform_feedback is not supported by mesa. Use transform feedback from core OpenGL 3.0. This necessitates binding the transform feedback varyings before linking the shader. Signed-off-by: Fabian Bieler <fabianbieler@fastmail.fm> Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>

2014-03-08glsl/gsraytrace: Use __LINE__ macro to set line numbers in GLSL source strings.Fabian Bieler1-3/+7
The hardcoded numbers are a few lines off at the moment. Keeping track of the numbers through further modifications is inconvenient. The __LINE__ "constant" takes care of this automatically. v2: (by Kenneth Graunke) Don't specify the source string number (caught by Ian Romanick).

2013-06-12glsl/gsraytrace: recursive ray tracing in gemetry shaders demoRALOVICH, Kristóf3-1/+957
Ray tracing using geometry shaders and transform feedback. Implements a simplified version of the algorithm described in K. Ralovich, M. Magdics: Recursive Ray Tracing in Geometry Shader, Proceedings of the Fifth Hungarian Conference on Computer Graphics and Geometry, Budapest, Hungary, 26 Jan 2010. The patch for automake comes from Brian Paul. Reviewed-by: Brian Paul <brianp@vmware.com>

2011-08-02Revert "cmake: Allow to specify glext headers include path."José Fonseca1-1/+0
I ran into build failures due to missing GL_UNSIGNED_INT_2_10_10_10_REV symbol, but it was caused by old glew headers, not old glext headers. So take this back until it actually makes a difference. This reverts commit 838c703bb9be6d89a226f2239dbb44c85d53da57.
