* 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

|
* 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

* 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.

* Redo all the GL_LINEAR interpolation code in terms of LERP macros/functions.Brian Paul2005-06-302-251/+279

* Previously in TXP and TEX instructions, lambda was passed toKeith Whitwell2005-05-111-3/+24
| | | | | | | | | | | | | | | | | | | | | fetch_texel as zero, but I believe this is incorrect. The spec uses a pseudocode function: vec4 TextureSample(float s, float t, float r, float lodBias, int texImageUnit, enum texTarget); to specify the behaviour of TEX, TXB and TXP instructions. For TEX and TXP, lodBias is passed as zero, TXB is passed with texcoord[4]. In our code we have static void fetch_texel( GLcontext *ctx, const GLfloat texcoord[4], GLfloat lambda, GLuint unit, GLfloat color[4] ) and were passing zero and a biased lambda value respectively. The difference is that TextureSample() would add in the lambda term itself, while in our code the caller is expected to do this. Thus in the TEX and TXP cases, it is necessary to pass an unbiased lambda value for things to work out correctly.

* Test for texcoord[3] == zero before dividing. Not so sure about thisKeith Whitwell2005-05-111-4/+15
| | | | | | test - if texcoord[3] is zero, we'd probably be fine except for an ASSERT in IROUND_POS() which gets triggered by the inf values created.

* Add a facility to route all rasterization through a fragment programKeith Whitwell2005-05-047-28/+28
| | | | | | | | | | | which is automatically generated to match the current texture environment state. Introduces a new value ctx->FragmentProgram._Active which is true when either _Enabled is true or there is such a fragment program ready to run. To test out on a driver running the software rasterizer, set MESA_TEX_PROG=t in the environment. It goes without saying that performance is lower for the software rasterizer in this mode.
