|

|

|
* disable some errant codeBrian2007-04-231-0/+2
|
* remove SWvertex->fog field, use attrib fieldBrian2007-04-237-13/+19
|
* Improve the code for interpolating fragment attributes a little. More to ↵Brian2007-04-237-222/+182

* Fix color sum bug 10688.Brian2007-04-214-15/+13
|
* Remove the !rb->Data check that was added a few months ago.Brian2007-04-212-2/+2
| | | | | Was changed while debugging #7205. Broke the shadowtext demo. Revisit this if the problem w/ bug 7205 returns...
* undo a test/debug changeBrian2007-04-211-1/+1
|
* Put gl_program_machine into swrast structure rather than using a local variable.Brian2007-04-192-10/+13
| | | | | Basically an easy way to make sure the memory gets initialized once (to zero) to avoid lots of valgrind warnings.
* remove invalid assertion (span->facing may be set because of polygonmode)Brian2007-04-191-2/+0
|
* Don't allow deferredTexture if using occlusion query and a frag shader.Brian2007-04-191-4/+17
| | | | | | Occlusion query might depend on the shader killing/discarding fragments. Helps fix depth peeling technique. Also, minor tweaks in interpolate_wpos().
* check _PreferPixelFog in _swrast_span_default_fog(), see bug 10669Brian2007-04-181-5/+14
|
* improved fog commentBrian2007-04-181-1/+1
|
* Enable texture sampling for vertex programs/shaders.Brian2007-04-172-2/+5
| | | | | | | This is a bit of a hack for now because the tnl module is using the swrast module to fetch texels. The texture fetch/filter code should probably be moved into the main/ module since it doesn't really depend upon other swrast code.
* Fix sample_depth_texture() to handle texture rectangle coords.Brian2007-04-141-30/+85
|
* fix negative zoom factor bug (10636), more commentsBrian2007-04-141-3/+11

* init span.y=0 to silence warningsBrian2007-04-041-0/+1
|
* Overlapping copies with zoomZ=-1 were broken. See bug 10521.Brian2007-04-041-47/+47
| | | | | Need to check for overlapping src/dest regions before computing bottom-to-top vs. top-to-bottom order.
* Restore the UseTexEnvProgram logic.Brian2007-03-272-2/+2
| | | | | Was removed during glsl-compiler work. Still need to go back and revisit this because of the interaction with fragment shaders...
* Add _swrast_span_default_secondary_color() for use with glBitmap, ↵Brian2007-03-265-2/+46
| | | | | | | glDrawPixels, etc. Secondary color wasn't getting added to post-texture color when drawing bitmaps, images. See bug 10409.

| | | | | | | | Also, fix an assertion.
* | Implement support for GL_ARB_draw_buffers with GL_MAX_DRAW_BUFFERS > 1.Brian2007-03-114-73/+148
| | | | | | | | | | | | GL_MAX_DRAW_BUFFERS is currently 4. Added gl_FragData[] output for fragment programs. In _swrast_write_rgba_span() loop over the color outputs/renderbuffers.
* | Implement gl_FrontFacing for fragment shaders.Brian2007-03-101-0/+4
| | | | | | | | | | | | For the time being, we put the gl_FrontFacing value in the FOGC.Y input register. Combining FOGC and FrontFacing in one register is a bit of a hack and may need to be changed someday.
