Jules Blok 8c55ec0d51 GeometryShaderGen: Perspective divide the line coordinates before comparing the angle. 2015-01-31 23:32:23 +01:00
Scott Mansell 1b771deb56 Move worldpos into it's own varying.
Previously it was packed into spare slots in clippos.xy and normal.w,
but it's ugly and more importantly it's causing bugs.

This was discovered during the debugging of a zfreeze branch, which
expected clippos.xy to be xy position coordinates in clipspace (as
the name suggested).

Turns out the stereoscopy shader had also run into this trap, modifying
clippos.x (introducing errors with per-pixel lighting).

This commit has been moved outside of the zfreeze PR for fast merging.

Jules Blok 7eb353b3bd VideoCommon: Don't pass structs between shaders, use the interface blocks instead. 2014-12-28 23:28:00 +01:00

Jules Blok 0d79e8f32b VideoCommon: Don't specify the redundant in/out qualifier if GL_ARB_shading_language_420pack is supported.
Some driver developers interpreted "can" as "must" in the OpenGL specs. (I'm looking at you AMD)

Jules Blok 27f3f804a0 ShaderGen: Only pass VS_OUTPUT between shaders if stereo 3D is enabled.
GLSL130 doesn't support passing structs between shaders.
This is not a problem for stereo 3D which has a GLSL150 requirement.
