* i965 Gen6: Implement gl_ClipVertex.Paul Berry2011-10-056-10/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements proper support for gl_ClipVertex by causing the new VS backend to populate the clip distance VUE slots using VERT_RESULT_CLIP_VERTEX when appropriate, and by using the untransformed clip planes in ctx->Transform.EyeUserPlane rather than the transformed clip planes in ctx->Transform._ClipUserPlane when a GLSL-based vertex shader is in use. When not using a GLSL-based vertex shader, we use ctx->Transform._ClipUserPlane (which is what we used prior to this patch). This ensures that clipping is still performed correctly for fixed function and ARB vertex programs. A new function, brw_select_clip_planes() is used to determine whether to use _ClipUserPlane or EyeUserPlane, so that the logic for making this decision is shared between the new and old vertex shaders. Fixes the following Piglit tests on i965 Gen6: - vs-clip-vertex-const-accept - vs-clip-vertex-const-reject - vs-clip-vertex-different-from-position - vs-clip-vertex-equal-to-position - vs-clip-vertex-homogeneity - vs-clip-based-on-position - vs-clip-based-on-position-homogeneity - clip-plane-transformation clipvert_pos - clip-plane-transformation pos_clipvert - clip-plane-transformation pos Reviewed-by: Kenneth Graunke <[email protected]> Reviewed-by: Chad Versace <[email protected]>
* mesa: Add a gl_vert_result for gl_ClipVertex.Paul Berry2011-10-052-22/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this patch, clip planes didn't work properly in Mesa when using vertex shaders, because Mesa assigned both gl_ClipVertex and gl_Position to the same gl_vert_result (VERT_RESULT_HPOS). As a result, backends couldn't distinguish between the two variables, so any shader that wrote different values to them would fail to work properly. This patch paves the way for proper support of gl_ClipVertex by creating a new enumerated value in gl_vert_result for it (VERT_RESULT_CLIP_VERTEX). After this patch, a back-end may add support for gl_ClipVertex using the following algorithm: - If using a user-supplied GLSL vertex shader: - If the bit corresponding to VERT_RESULT_CLIP_VERTEX is set in gl_program::OutputsWritten: - Clip using the vertex shader output VERT_RESULT_CLIP_VERTEX and the clip planes defined in gl_context::Transform.EyeUserPlane. - Else: - Clip using the vertex shader output VERT_RESULT_HPOS and the clip planes defined in gl_context::Transform.EyeUserPlane. - Else (either using fixed function or an ARB vertex program): - Clip using the vertex shader output VERT_RESULT_HPOS and the clip planes defined in gl_context::Transform._ClipUserPlane (*) where (*) represents the normal Mesa behavior before this patch. An example of implementing the above algorithm can be found in the patch that follows this one, which implements gl_ClipVertex in i965 Gen6. Reviewed-by: Kenneth Graunke <[email protected]>
* llvmpipe: Fix the 4 planes (lines) case properly.José Fonseca2011-10-052-16/+33
| | | | | | | | The previous change was not effective for lines, because there is no 4 planes 4x4 block rasterization path: it is handled by the 16x16 block case too, and the 16x16 block was not being budged as it should. This fixes assertion failures on line rasterization.
* llvmpipe: Ensure the 16x16 special rasterization path does not touch outside ↵José Fonseca2011-10-054-5/+31
| | | | | | | | | | | | | | the tile. llvmpipe has a few special rasterization paths for triangles contained in 16x16 blocks, but it allows the 16x16 block to be aligned only to a 4x4 grid. Some 16x16 blocks could actually intersect the tile if the triangle is 16 pixels in one dimension but 4 in the other, causing a buffer overflow. The fix consists of budging the 16x16 blocks back inside the tile.

| | | | | | | | | | | | Commit d1fda903 (radeon: Drop mapping we were doing around glGetTexImage()) removed the common Radeon source file radeon_tex_getimage.c, and pulled it out of the r200, r300, r600, and radeon makefiles.
