Rendering of the demo has improved, the only thing missing now is the shadow.

Created attachment 46775 [details] Screenshot of bug The shadow mapping demo from norsetto doesn't render correctly with r600g, none of the objects are textured and the shadows are missing. Rendering on llvmpipe seems to be correct. The demo requires a simple change for the shaders to compile: --- data/shaders/bumpTBN_SH_FP.glsl.orig 2011-05-16 17:41:49.098224141 +0200 +++ data/shaders/bumpTBN_SH_FP.glsl 2011-05-16 17:41:57.978477020 +0200 @@ -46,7 +46,7 @@ void main() offset.y += offset.x; if ( offset.y > 1.1) - offset.y = 0; + offset.y = 0.0; vec4 shadow = ( offset_lookup( shadowMap, gl_TexCoord[1], offset+vec2(-1.5, 0.5) ) + offset_lookup( shadowMap, gl_TexCoord[1], offset+vec2( 0.5, 0.5) ) + System environment: -- system architecture: 32-bit -- Linux distribution: Debian unstable -- GPU: REDWOOD -- Model: XFX Radeon HD 5670 1GB -- Display connector: DVI -- xf86-video-ati: 6.14.1 -- xserver: 1.10.1 -- mesa: git-c9aa3bb -- drm: 2.4.25 -- kernel: 2.6.39-rc7
