2005-07-18pass in the renderbufferAlan Hourihane
2005-07-01Remove NEW_RENDERBUFFER stuff.Brian Paul
Now, OLD_RENDERBUFFER marks code that needs to eventually be removed when all the drivers are updated to no longer need the SetBuffer() function.

2005-06-30Redo all the GL_LINEAR interpolation code in terms of LERP macros/functions.Brian Paul
This cleans up and simplifies the arithmetic quite a bit.

fog.
2005-05-11Previously in TXP and TEX instructions, lambda was passed toKeith Whitwell
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.

2005-05-11Test for texcoord[3] == zero before dividing. Not so sure about thisKeith Whitwell
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.

2005-05-04Major check-in of changes for GL_EXT_framebuffer_object extension.Brian Paul
Main driver impacts: - new code for creating the Mesa GLframebuffer - new span/pixel read/write code Some drivers not yet updated/tested.
2005-05-04Add a facility to route all rasterization through a fragment programKeith Whitwell
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.
