* Fix broken line clipping.Brian Paul2006-10-181-3/+8
| | | | | | | When both ends of the line were clipped, we were using the new v0 instead of the original v0 when computing the location of the second vertex. Thus, the second vertex's position was incorrect. Thanks to Heath Feather for finding a test case.
* Fix a dangerous use of ASSERT in an else-clause not enclosed in braces.Brian Paul2006-10-181-2/+4
| | | | We've been lucky if this hasn't been causing line rendering bugs.
* List of source (.c) files in each directory.Brian Paul2006-10-111-0/+31
| | | | | To be included by X.org Makefile.am files so that lists of files don't need to be hardcoded and frequently updated there.
* a step toward moving run-time vertex program state out of GLcontextBrian Paul2006-10-101-4/+4
|
* do not import arrays for generic arb attribs if the array is not enabled ↵Roland Scheidegger2006-10-071-2/+3
| | | | (same as for generic attribs for nv vp is already done). Since the requested stride is 16, otherwise the code would end up doing lots of unnecessary import work (in doom3, trans_4_GLfloat_4f_raw caused by that was by far the single most time-consuming function in the r200 driver, not importing the disabled arrays caused the cpu time spent in the driver to drop from 45% to 30%, though real-world gain was pretty minimal as it's not really cpu bound here in the first place).
* bring in active_sz mechanism from i965 driver. Fixes bug 8410Keith Whitwell2006-09-252-7/+17

* only allow VERT_ATTRIB_MAX instead of _TNL_ATTRIB_MAX for inputs of vertex ↵Roland Scheidegger2006-09-072-2/+2
| | | | programs (fixes a segfault since the result of the shift is undefined otherwise, and it may happen that _TNL_ATTRIB_POINTSIZE will be tried to read, unlike all other attribs this however may be unitialized (might be a bug in itself)).
* Remove XFree86 CVS keyword.Brian Paul2006-08-253-3/+0

* In _save_End(), set CurrentExecPrimitive = PRIM_OUTSIDE_BEGIN_END ifBrian Paul2006-08-251-0/+3

* use ctx->Light.ShadeModel instead of ctx->_TriangleCapsBrian Paul2006-07-201-3/+3
|
* Several loops over the map1/2 evaluator arrays were incorrect.Brian Paul2006-07-193-19/+33
| | | | | | | | There's only 16 evaluator maps. Define new _TNL_NUM_EVAL constant for those loops. Also, fix priority of GL_NV_vertex_program generic maps - they override the conventional maps. See bug 7564.
* added _TNL_NUM_GENERICTilman Sauerbeck2006-06-291-0/+2
|
* Don't use nested struct definitions in tnl_clipspace_fastpath.Brian Paul2006-06-272-7/+9
| | | | | Make attr_type into a top-level type: tnl_attr_type See bug 7340.

* A number of vertex buffer fields like NormalPtr, FogCoordPtr, etc are reallyBrian Paul2006-06-1411-73/+76
| | | | | | just aliases for members of the VB->AttribPtr[] array. Begin replacing FogCoordPtr with VB->AttribPtr[_TNL_ATTRIB_FOG], and similarly for NormalPtr, TexCoordPtr, PointSizePtr, etc.

| | | | | | | 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.

| | | | | | Update a lot of loops, conditionals to use the _TNL_FIRST/LAST_* values instead of specific vertex attributes. Remove the EdgeFlagv function from the GLvertexformat struct.

* Replace ctx->Const.MaxTextureUnits w/ ctx->Const.MaxTexture[Coord/Image]UnitsBrian Paul2006-04-144-7/+7

* More GLSL code:Michal Krol2006-04-115-140/+171
| | | | | | | | | | | | - use macros to access and modify render inputs bit-field; - un-alias generic vertex attributes for ARB vertex calls; - use MAX_VERTEX_PROGRAM_ATTRIBS (NV code) or MAX_VERTEX_ATTRIBS (ARB code) in place of VERT_ATTRIB_MAX; - define VERT_ATTRIB_GENERIC0..15 for un-aliased vertex attributes for ARB_vertex_shader; - fix generic attribute index range check in arbprogparse.c; - interface GLSL varyings between vertex and fragment shader; - use 64-bit optimised bitset (bitset.h) for render inputs;
* Rename CLIP_ALL_BITS to CLIP_FRUSTUM_BITS to reflect the fact that the valueBrian Paul2006-04-065-5/+7
| | | | | only includes the 6 frustum bits, not the user-clip plane bit, nor the vertex cull bit.
* Fix line clipping bug 6512.Brian Paul2006-04-061-24/+28
| | | | This fix is to discard the line if both dot products are negative.
* Coverity #476: Avoid walking off the end of ->vtx.attrsz, it's declared toAdam Jackson2006-04-021-1/+1
| | | | | | | | be _TNL_ATTRIB_MAX long so that's not a valid index (woo zero based indexing). This code still looks wrong though, the asymmetry between _tnl_copy_to_current and _tnl_copy_from_current has me worried.
* GLSL fixes:Michal Krol2006-03-2111-15/+15
| | | | | | | | | | | | | | | | | | - generate error on NULL pointers in glShaderSourceARB; - reinstall program object, if current, in glLinkProgramARB; - vertex and fragment shaders are optional in program object; - floor asm was wrongly computed for x86 back-end; - allow for (void) idiom in function prototypes; - all fixed-state uniforms are updated; - local variable initializers are working; - implement texture* and shadow* functions for vertex processor; - generate error if too many arguments in general constructor; - trim unused data in general constructor; - struct r-value field select was badly relocated; Changes: - add derived state gl_fog_attrib::_Scale; - add derived state gl_light::_CosCutoffNeg;
