|
* use mesa import wrappers, bug 4468Brian Paul2005-09-161-2/+2
|
* Rework the texture filtering functions a bit.Brian Paul2005-09-167-128/+103
| | | | No need to pass the texture unit number as an argument.
* replace a couple macros with inlined functionsBrian Paul2005-09-161-60/+48
|
* more GLuint->GLbitfield changesBrian Paul2005-09-163-8/+8
|
* Replace GLuint with GLbitfield where appropriate. Also replace GLuintBrian Paul2005-09-154-12/+12
| | | | with GLboolean in a few places.
* Code clean-ups, reorg.Brian Paul2005-09-151-184/+153
|
* updated commentsBrian Paul2005-09-151-11/+9
|
* Update includes post-splitting of s_texture.cBrian Paul2005-09-158-9/+3
|
* Split the s_texture.c file into two new files:Brian Paul2005-09-155-1431/+1451
| | | | | s_texcombine.c - for texture combining/application s_texfilter.c - for texture sampling/filtering
* OpenGL 2.0's two-sided stencil feature wasn't implemented correctly.Brian Paul2005-09-131-1/+1
| | | | | See comment near top of stencil.c for info about OpenGL 2.0 vs. GL_EXT_stencil_two_side.
* Clear either 8 or 16-bit stencil buffers.Brian Paul2005-09-131-27/+66
|
* fix some bugs with handling of GL_DOT4_ATI, GL_DOT3_ATI and GL_DOT2_ADD_ATI ↵Roland Scheidegger2005-09-091-5/+9
| | | | ATI_fs instructions.
* fix precision problem in depth clearing (bug 4395)Brian Paul2005-09-081-4/+10
|
* fix bug with ATI_fragment_shader in swrast (need to copy all 4 values due to ↵Roland Scheidegger2005-09-071-6/+4
| | | | later applied srcRep)
* minor clean-up of texture_combine()Brian Paul2005-09-061-12/+9
|
* don't use DEFARRAY/CHECKARRAY stuffBrian Paul2005-09-063-11/+3
|
* remove obsolete CurrentBufferBitBrian Paul2005-09-052-6/+0
|
* remove unused varBrian Paul2005-09-051-1/+0
|
* Remove last remnants of pre-renderbuffer code.Brian Paul2005-09-039-259/+11
|
* Check for ATI_fragment_shader enabledDave Airlie2005-09-021-1/+2
|
* ATI_fragment_shader fixes: fix bug in passTexCoord (caused by recent ↵Roland Scheidegger2005-09-022-36/+37
| | | | changes). Fix sampling from wrong texture unit. Apply swizzling before texture sampling, and hopefully get non-projected coordinates from swrast. (still does not work at all with sw doom3, way too dark just the same as with the doom3 arb2 path)
* add error checking to the GL_ATI_FRAGMENT_SHADER entrypoints. Fix bug with ↵Roland Scheidegger2005-09-021-35/+31
| | | | scope of ati fragment shader constants. Fix issues with specifying color/alpha instructions not pair-wise. Change internal representation of the shader (to better fit how the extension works, should make driver implementations simpler, and saves some memory). (still doesn't work correctly with doom3 and swrast, but not worse than before)
* Just additional comments.Brian Paul2005-08-311-1/+7
|
* Rearrange the code related to GL_ARB_occlusion_object to generalize queryBrian Paul2005-08-273-16/+19
| | | | objects for future types of queries.
* removed GL_HP_occlusion_test extensionBrian Paul2005-08-254-25/+9
|
* also check for texture border in sample_linear_2d()Brian Paul2005-08-251-2/+3
|
* improve comments about win[0..3] values (bug 2554)Brian Paul2005-07-261-2/+5
|
* s/clippping/clipping/Brian Paul2005-07-181-2/+2
|
* pass in the renderbufferAlan Hourihane2005-07-181-1/+1
|
* Remove NEW_RENDERBUFFER stuff.Brian Paul2005-07-016-11/+7
| | | | | Now, OLD_RENDERBUFFER marks code that needs to eventually be removed when all the drivers are updated to no longer need the SetBuffer() function.
* remove OLD_RENDERBUFFER codeBrian Paul2005-07-011-87/+16
|
* Redo all the GL_LINEAR interpolation code in terms of LERP macros/functions.Brian Paul2005-06-302-251/+279
| | | | This cleans up and simplifies the arithmetic quite a bit.
* check for NULL swrast->Driver.SetBuffer before calling itBrian Paul2005-06-212-4/+7
|
* be sure we have span texcoords before calling _swrast_texture_span()Brian Paul2005-06-101-2/+2
|
* pass mask array to PutRowRGB() in simple_z_textured_triangle()Brian Paul2005-06-101-1/+2
|
* set OLD_RENDERBUFFER=0, need to clean up a few more things before totally ↵Brian Paul2005-06-041-1/+1
