2006-07-20 | Some structure renaming. Prefix vertex/fragment-related structs with | Brian Paul | |
"gl_" to match other structs. | |||
2005-11-20 | Make Saturate a 2-bit field again, renamed to SaturateMode with three | Brian Paul | |

2005-11-12 | update an assertion | Brian Paul | |
2005-11-12 | Move stuff common to vertex/fragment_program into the base class, including: | Brian Paul | |
Instructions, InputsRead, OutputsWritten, and Parameters. Also, added debug functions: _mesa_print_instruction(), _mesa_print_program_parameters() and revamp _mesa_print_program(). | |||

2005-05-11 | Previously in TXP and TEX instructions, lambda was passed to | Keith 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. | |||
2005-05-11 | Test for texcoord[3] == zero before dividing. Not so sure about this | Keith 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. | |||
2005-05-04 | Major 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. | |||
2005-05-04 | Add a facility to route all rasterization through a fragment program | Keith 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. | |||
2005-04-21 | Reduce the size of mesa's internal fragment and vertex program | Keith Whitwell | |
representations by switching to packed structures for registers and instructions. | |||
2004-12-18 | Added PRINT instruction for GL_NV_fragment_program. | Brian Paul | |
2004-12-15 | tweaks to the LIT instructions | Brian Paul | |
2004-08-10 | added a few more debug printfs (disabled) | Brian Paul | |
2004-06-20 | store's to RC/HC didn't work (bug 976287) | Brian Paul | |
2004-04-21 | only init temp regs to zero if executing NV fragment program | Brian Paul | |
2004-04-18 | Audit/fixes for NV/ARB TEX, TXP, TXB, TXD instructions. | Brian Paul | |
Some texture instructions were using wrong LOD. Fixed interpolate_texcoords() so it doesn't do texcoord projective division when using a fragment program. The TXP instruction does that. | |||
2004-04-14 | Use tcc and the emitted C code from s_fragprog_to_c.c to dynamically compile | Keith Whitwell | |
and execute fragment programs. Very limited and experimental, but works well enough to run arbfplight.c. http://fabrice.bellard.free.fr/tcc/ Compile with 'make linux-tcc', being sure to make clean first. | |||

2004-01-23 | Initial support for floating point and signed texture formats. | Brian Paul | |
New "FetchTexelFuncF()" function returns texels in floating point format. Only used for depth component images at this time. Changed original FetchTexelFunc to return GLchan instead of GLvoid, removing need for a bunch of ugly casts. | |||
