2009-01-23Track two sets of back-face stencil stateIan Romanick
Track separate back-face stencil state for OpenGL 2.0 / GL_ATI_separate_stencil and GL_EXT_stencil_two_side. This allows all three to be enabled in a driver. One set of state is set via the 2.0 or ATI functions and is used when STENCIL_TEST_TWO_SIDE_EXT is disabled. The other is set by StencilFunc and StencilOp when the active stencil face is set to BACK. The GL_EXT_stencil_two_side spec has more details. http://opengl.org/registry/specs/EXT/stencil_two_side.txt
2009-01-16mesa: remove GL_DEPTH_TEST + no depth buffer testBrian Paul
One could enable depth testing before binding an FBO that has a depth buffer so this test is no longer useful or correct.
2008-12-31mesa: increase max texture image units and GLSL samplers to 16Brian Paul
The max texture coord units is still 8. All the fixed-function paths are still limited to 8 too. But GLSL shaders can use more samplers now. Note that some texcoord-related data structures are declared to be 16 elements in size rather than 8. This just simplifies the code in a few places; the extra elements aren't accessible to the user. These changes haven't been extensively tested yet, but sanity checking has been done. It should be possible to increase the max image units/samplers to 32 without doing anything special. Beyond that we'll need longer bitfields in a few places.
2008-09-21mesa: point size arraysBrian Paul
2008-08-21Call _ae_update_state when array enable state changesKrzysztof Czurylo
Basically, the application enables client vertex and color arrays, renders something, then disables color array, and renders something else (using vertex array only). Even though the color array is disabled (and the pointer is no longer valid), the driver still tries to read color data from this array (which results in an exception). This is because enabling/disabling array does not trigger _ae_update_state() and the list of enabled arrays is not updated. _ae_update_state() it's called on the first state validation only (as all the "dirty" flags are set at the beginning). Any further change to client arrays' state has no effect.

2007-05-16Initial implementation of MESA_texture_arrayIan Romanick
Shadow sampling from texture arrays is still not implemented. Everything else should be there, though.
2007-05-10Fix reversed enable logic in enable_textureIan Romanick
Fix bug inserted in commit c9e723e5013443df984cb3987ffa3a9ba3384b89. Discovered by Oliver McFadden (z3ro).
2007-05-10Convert "bit" parameters to GLbitfield. Fix cut-and-paste bug in _mesa_IsEnabledIan Romanick
These changes are based on patch review comments from Brian Paul, Alan Hourihane, and vehemens.

2007-03-16Colortable re-org.Brian
The pixel transfer path has three color table lookups. Use an array [3] to store that info, rather than separate variables.

2006-12-13Move all the code for computing ctx->_TriangleCaps into state.c.Brian
ctx->_TriangleCaps should probably go away altogether someday...
2006-10-30better handling of current attributes. Trivial dlist and varray tests workKeith Whitwell
2006-07-18Compute ctx->Color._LogicOpEnabled in one place instead of four places!Brian Paul
2006-06-12Add support for GL_APPLE_vertex_array_object. Several test programsIan Romanick
and demos are also added. Adding basic support to drivers should be as easy as just enabling the extension, though thorough test would also be required.
2006-03-03Use standard ARB names instead of vendor-specific NV names for the ↵Roland Scheidegger
ARB/NV_vertex_program enums in common state handling code, and update comments accordingly. Change some slightly confusing code which gave the impression GL_VERTEX_PROGRAM_ARB and GL_VERTEX_PROGRAM_NV enums were different.
2006-03-02Fix more enums defined not only by one extension when queried by glGet ↵Roland Scheidegger
(GL_COLOR_SUM_EXT, GL_POINT_SPRITE_NV, GL_POINT_SPRITE_COORD_ORIGIN, GL_TRANSPOSE_CURRENT_MATRIX_ARB). Fix similar bugs (also those previously overseen dependant on NV/ARB_vertex_program) in glIsEnabled. Add missing GL_COLOR_SUM_EXT enum to glIsEnabled.
2006-03-01Fix glGet with enums which are used not only in NV_vertex_program, but other ↵Roland Scheidegger
extensions too (ARB_vertex_program, ARB_fragment_program, NV_fragment_program), if no support for NV_vertex_program is present. While here, fix return value if enum is used which is not supported by the exposed extensions (GL_INVALID_ENUM instead of GL_INVALID_VALUE). Fix some compile-time #ifs depending on NV_vertex/fragment_program which should also be dependant on ARB_vertex/fragment_program. See bug #6070
2005-12-14Removed the GL_SGIX/SGIS_pixel_texture extensions. Same thing can beBrian Paul

2005-08-25removed GL_HP_occlusion_test extensionBrian Paul
2005-06-30Add a set of predicate functions for testing matrices instead of directlyBrian Paul

2002-10-24Header file clean-up:Brian Paul
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.
2002-10-16surround vertex program code with #if FEATURE_NV_vertex_program/#endifBrian Paul
2002-09-06GL_EXT_stencil_two_side extension, not 100% complete yet.Brian Paul
2002-06-29Applied Matt Sealey's patch to remove/isolate all stdio.h function calls.Brian Paul

Finished all glGet* queries for GL_NV_vertex_program. Improved error reporting in glEnable/Disable/Get, etc.
2002-06-15Implemented GL_NV_texture_rectangle extension.Brian Paul
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.
