* Merge SWvertex texcoord and varying fields into attrib[] array field.Brian2007-02-051-28/+3
| | | | | Fragment texcoords and varying code is now unified in the point/line/triangle rasterization code. In the future, merge color, fog, etc. attribs.
* Replace color, z, w, texture interpolants with new generic attrib interpolants.Brian2007-02-021-7/+7
|
* Checkpoint for GLSL compiler changes.Brian2006-12-131-7/+8
| | | | | | In brief: Check for enabled fragment program by looking at ctx->FragmentProgram._Current. New code for varying variables.
* New SWspan and SWspanarrays typedefs.Brian Paul2006-10-011-2/+2

* Use new gl_framebuffer _Depth/_StencilBuffer fields instead ofBrian Paul2005-11-161-2/+1
| | | | | Attachment[BUFFER_DEPTH/STENCIL].Renderbuffer. The former may be wrappers around combined depth/stencil renderbuffers attached at the later points.
* Remove _IsPowerOfTwo from gl_texture_object, not really needed.Brian Paul2005-10-051-1/+1
|
* In gl_texture_image replace IntFormat with InternalFormat and Format withBrian Paul2005-10-051-2/+2
| | | | _BaseFormat to be consistant with gl_renderbuffer.
* replace GLdepth with GLuint and remove GLdepthBrian Paul2005-09-211-2/+2

* Rearrange the code related to GL_ARB_occlusion_object to generalize queryBrian Paul2005-08-271-11/+12
| | | | objects for future types of queries.
* removed GL_HP_occlusion_test extensionBrian Paul2005-08-251-5/+3
|
* Redo all the GL_LINEAR interpolation code in terms of LERP macros/functions.Brian Paul2005-06-301-43/+43
| | | | This cleans up and simplifies the arithmetic quite a bit.
* pass mask array to PutRowRGB() in simple_z_textured_triangle()Brian Paul2005-06-101-1/+2
|
* Remove last of the old span code.Brian Paul2005-06-021-14/+2
|
* Major check-in of changes for GL_EXT_framebuffer_object extension.Brian Paul2005-05-041-9/+19
| | | | | | | Main driver impacts: - new code for creating the Mesa GLframebuffer - new span/pixel read/write code Some drivers not yet updated/tested.
* Add a facility to route all rasterization through a fragment programKeith Whitwell2005-05-041-2/+2
| | | | | | | | | | | 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.
* Consolidate _swrast_write_texture_span() into _swrast_write_rgba_span().Brian Paul2004-12-181-3/+9

* Silence gcc 3.4 warnings on ReactOS. Mostly unused var warnings. (patch ↵Brian Paul2004-08-251-1/+1

* fix HP occlusion testing when using generic span pathBrian Paul2004-06-241-1/+0
|
* Fixed occlusion_zless_triangle() to work with 16 or 32-bit Z buffers.Brian Paul2004-06-231-20/+32
| | | | Removed some unneeded lines, other minor clean-ups.
* only use simple_z_textured_triangle if depthBits <= 16Brian Paul2004-05-251-1/+3

* Added ctx->Vertex/FragmentProgram._Enable flags. Set when vertex/fragmentBrian Paul2004-04-231-2/+2
| | | | | | | program is enabled AND the currently bound program is valid. Check _Enable instead of Enable to prevent things from blowing up when someone calls glEnable(GL_VERTEX_PROGRAM_ARB) without actually defining a program.
* Fix color index mode rendering.Brian Paul2004-03-091-1/+1
| | | | Changed SWvertex's index field to GLfloat and fix a few other bits.
* A bit of an overhaul of the fog code.Brian Paul2004-02-171-0/+1
| | | | | | glFogCoord didn't always work reliably. ARB fragment program fog options work now. Per-fragment fog computations are now perspective corrected.

* Update NEED_SECONDARY_COLOR macro to test if either vertex/fragmentBrian Paul2003-12-091-1/+1

| | | | | | Fixed some vertex array / vertex program glitches with glDrawElements. Fixed some fragment program runtime bugs. Non-trivial Cg programs are running now.

* Clean-up of parser error handling/reporting.Brian Paul2003-03-141-1/+2

* Header file clean-up:Brian Paul2002-10-241-2/+2
| | | | | | | | 1. Remove all.h and PC_HEADER junk. 2. Rolled mem.c and mem.h into imports.c and imports.h 3. Include imports.h instead of mem.h Restore _mesa_create/initialize_context() to be like they were in 4.0.4 New wrappers for a few std C functions: _mesa_atoi(), _mesa_strstr(), etc.
* merge gl_texture_image RowStride from DRI 4.0.4Brian Paul2002-09-231-1/+2

* struct sw_span is again allocated on the stack, but the arrays of spanBrian Paul2002-08-071-61/+62
| | | | | | | 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.
