* | New SWspanarrays attribs[] array.Brian2007-02-011-1/+1
|/ | | | | | | Replace texcoord[], varying[], etc. arrays with single attribs[] array, indexed by FRAG_ATTRIB_* values. Eliminates need to copy data into fragment program machine input registers. Will lead to future clean-ups.
* Make sure RENDER_FINISH is called on the zero pixel case. Reported byKeith Whitwell2006-11-141-1/+1

* In _mesa_pack_rgba_span_float() we don't need to make a temporary copy ofBrian Paul2006-10-131-4/+2
| | | | | | | incoming colors when applying pixel transfer ops. In all cases, the caller either indicates there's no pixel transfer ops, or the incoming colors are coming from temporary storage already and can be safely modified.

* adjust_colors() function replaces old _mesa_chan_to_float_span() function.Brian Paul2006-10-121-26/+45
|
* Lots of changes to support runtime renderbuffer depths.Brian Paul2006-10-121-54/+74
| | | | | | _swrast_read_rgba_span() now takes a datatype parameter. New optimization for glReadPixels(format=GL_RGB). New glCopyPixels optimization for the simple, common cases.

* replace GLdepth with GLuint and remove GLdepthBrian Paul2005-09-211-10/+5

|
* Major check-in of changes for GL_EXT_framebuffer_object extension.Brian Paul2005-05-041-30/+61
| | | | | | | Main driver impacts: - new code for creating the Mesa GLframebuffer - new span/pixel read/write code Some drivers not yet updated/tested.
* GL_(UN)PACK_SKIP_IMAGES should only be applied to 3D texture pack/unpackingBrian Paul2004-11-101-15/+15
| | | | | | | and ignored for 1D and 2D images. Need to pass in image dimensions (1,2,3) to the _mesa_image_address() function. This change gets propogated to some other routines. Also added new _mesa_image_address[123]d() convenience functions.
* use the new _mesa_clip_readpixels() routineBrian Paul2004-11-091-34/+37
|
* don't use ctx->Pack, use the function argumentBrian Paul2004-11-091-13/+12
|
* Allow the software fallback glDrawPixels, glReadPixels, glBitmap commands toBrian Paul2004-10-311-9/+29
| | | | | work with real, hardware-based PBOs in the future by mapping/unmapping the PBO buffer as needed.
* New glTexImage code.Brian Paul2004-04-221-1/+7
| | | | | | | | The gl_texture_format struct now has a StoreTexImageFunc that's called by glTex[Sub]Image[123]D to convert the user's texture data into the specific texture format layout. Now it's much easier to add new texture formats (like the 16/32-bit floating point formats). The texutil.[ch] and texutil_tmp.h files are obsolete.
* Implementation of GL_EXT_pixel_buffer_object extension.Brian Paul2004-03-131-7/+15
| | | | | Note: extension may not be finalized yet - subject to change! Note: implementation not fully suitable for h/w implementation yet.
* rename some span pack/unpack functions for better uniformityBrian Paul2004-02-281-4/+4
|
* added missing <type> error checking in read_index_pixels()Brian Paul2003-11-181-3/+13

* Removed all RCS / CVS tags (Id, Header, Date, etc.) from everything.Ian Romanick2003-06-051-1/+0

* replace _mesa_ prefix with _swrast_, remove s_histogram.[ch]Brian Paul2003-03-251-8/+8
|
* 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.
* GL_MESA_pack_invertBrian Paul2002-09-211-2/+9
|
* Overhaul of glRead/DrawBuffer() code. Now, swrast->Driver.SetBuffer()Brian Paul2002-07-091-9/+6
| | | | | indicates the read AND draw color buffer for all software rasterization. Lots of related clean-ups. See RELNOTES-4.1 for details.
* casts to fix GLint/GLuint mismatchesBrian Paul2002-04-191-5/+5
