* init swrast->CurrentBufferBrian Paul2002-10-111-1/+6
|
* Another round of glRead/DrawBuffer() clean-ups and simplifications.Brian Paul2002-10-115-67/+40
| | | | | | | Replaced ctx->Color._DriverDrawBuffer with swrast->CurrentBuffer. Replaced ctx->Pixel._DriverReadBuffer with ctx->Pixel._ReadSrcMask. swrast->Driver.SetBuffer() takes FRONT/BACK_LEFT/RIGHT_BIT values now. Added tokens and code for GL_AUX buffers, for completeness.
* finally get rid of ctx->Texture._ReallyEnabled fieldBrian Paul2002-10-081-3/+3
|
* remove const storage class specifier for the decl of a var that isn'tKarl Schultz2002-10-041-2/+2
| | | | a const.
* Changed a number of context fields from GLchan to GLfloat (such as ClearColor).Brian Paul2002-10-044-54/+58
| | | | | | Also changed parameter types for some driver functions (like ctx->Driver.Clear- Color). Updated all the device drivers. Someday, we want to support 8, 16 and 32-bit channels dynamically at runtime.
* multiple GL_POINTS can now be rendered together into one fragment spanBrian Paul2002-10-044-125/+240

* finished up GL_EXT_stencil_two_sideBrian Paul2002-10-025-15/+19
|
* new texture compression infrastructureBrian Paul2002-09-271-98/+48
|
* merge gl_texture_image RowStride from DRI 4.0.4Brian Paul2002-09-232-4/+7
|
* GL_MESA_pack_invertBrian Paul2002-09-211-2/+9
|
* updates from 4.0.4 (MESA_ycbcr_texture, APPLE_client_storage, etc)Brian Paul2002-09-211-2/+3
|
* pull-in changes from DRI/Mesa-4.0.4Brian Paul2002-09-172-2/+25
|
* fixed _mesa_generate_mipmaps() target problemBrian Paul2002-09-161-8/+8
|
* GL_EXT_stencil_two_side extension, not 100% complete yet.Brian Paul2002-09-063-87/+95
|
* re-check-in - something didn't work on the previous check-inBrian Paul2002-08-071-164/+164
|
* struct sw_span is again allocated on the stack, but the arrays of spanBrian Paul2002-08-0723-908/+1007
| | | | | | | data are broken out into a new struct span_arrays which is allocated per-context (to avoid huge stack allocations - a problem on Windows). This lets us use span.redStep instead of span->redStep (for example) to hopefully get slightly better performance in the triangle functions.
* Overhaul of glRead/DrawBuffer() code. Now, swrast->Driver.SetBuffer()Brian Paul2002-07-0911-196/+244
| | | | | indicates the read AND draw color buffer for all software rasterization. Lots of related clean-ups. See RELNOTES-4.1 for details.
* blending fixes for CHAN_TYPE==GL_FLOAT (Gerk Huisma)Brian Paul2002-06-301-1/+38

* fix CHAN_TYPE==GL_FLOAT compile problemBrian Paul2002-06-261-3/+5
|
* Implemented GL_NV_texture_rectangle extension.Brian Paul2002-06-1511-51/+248
| | | | | | | | | Replace struct gl_texure_object's Dimension w/ Target field. Added _EnabledUnits to struct gl_texture_attrib - the _ReallyEnabled field is obsolete, but still present for now. This effectively removes the 8-texture units limit, 32 units now possible, but unlikely! New TEXTURE_1D/2D/3D/CUBE/RECT_BIT tokens for unit->_ReallyEnabled field. Updated device drivers to use ctx->Texture._EnabledUnits.
* Added ctx parameter to _mesa_debug()Brian Paul2002-06-156-40/+119
| | | | | | Added _mesa_printf() Updated SetDrawBuffer() function in all drivers (ala 4.0.3) Import 4.0.3/DRI changes.
