* Add do_row_3d for mipmapping 3D texturesIan Romanick2008-12-191-21/+444
| | | | | | | | | | | | Previously 3D textures were mipmapped using multiple passed through the 2D mipmap generation code. This had 3 disadvantages. First, the extra passes were slow. Second, this required the allocation of a temporary buffer to hold intermediate data. Third, and most important, the extra passes caused loss of additional bits due to integer division / bit-shifting. With this change, our mipmapgen conformance test passes for non-compressed texture formats.
* Fix typeo in mipmap filter for GL_UNSIGNED_SHORT_1_5_5_5_REVIan Romanick2008-12-191-1/+1

* mesa: Clip copytexsubimage to read framebuffer bounds, not scissor region.Eric Anholt2008-12-181-1/+1
|
* mesa: Correct _mesa_clip_to_region() off-by-one.Eric Anholt2008-12-181-2/+2
| | | | | | | | | | Note how if: x + width == xmax + 0: width -= 0 x + width == xmax + 1: width -= 0 x + width == xmax + 2: width -= 1 So, the function was clipping to [xmin, xmax+1), not [xmin, xmax) like it was supposed to. Same for ymax.
* mesa: remove unneeded _mesa_reference_fragprog() callBrian Paul2008-12-171-4/+2
| | | | The subsequent if/else cases always call _mesa_reference_fragprog() anyway.

* Perform range checking on app supplied texture base levelIan Romanick2008-12-141-0/+12
| | | | | | | | | It is possible for applications to specify any texture base level, including trivially invalid values (i.e., 47000000). When an app specifies an invalide base level, we should gracefully disable the texture instead of accessing memory outside the gl_texture_object. This fixes an occasional segfault in one of our conformance tests.
* mesa: Fix GenerateMipmapEXT(GL_TEXTURE_CUBE_MAP_ARB).Eric Anholt2008-12-061-2/+10
| | | | | | The ctx->Driver.GenerateMipmap() hook only expects cubemap face enums, not CUBE_MAP_ARB, so walk all faces when we encounter that. Fixes oglconform fbo.c segfault with both swrast and i965 drivers.
* mesa: fix conditional in save_Lightfv(), bug 18838Brian2008-12-011-1/+1

* mesa: remove unneeded compressed texure size checksPhillip Klaus Krause2008-11-281-6/+0
|
* mesa: add gl_program::Input/OutputFlags[] arrayBrian Paul2008-11-242-0/+5
| | | | | These arrays will indicate per-input or per-output options for vertex/fragment programs such as centroid-sampling and invariance.
* mesa: fix shadow sampling unit issue.Xiang, Haihao2008-11-201-1/+6
| | | | | texture comparison logic is bypassed if the currently bound texture is not a depth/depth_stencil texture.
* mesa: clamp luminance if needed.Xiang, Haihao2008-11-192-2/+10
| | | | | This fixes glReadPixels(GL_LUMINANCE, GL_FLOAT)/glGetTexImage(GL_LUMINANCE, GL_FLOAT) issue on fixed-point color buffers.
* mesa: fix generation of fixed function state when no vp existsAlan Hourihane2008-11-131-43/+41
|
* mesa: restore the negate flag of dots in build_lighting.Xiang, Haihao2008-11-111-0/+3
| | | | | Dots is re-used if more than one light is enabled. Previously the negate flag of dots may affect next light.
* mesa: update new state for RasterPos like other operations.Xiang, Haihao2008-11-111-3/+3
| | | | This fixes a lighting issue when drawing a bitmap.
* mesa: new _mesa_is_pow_two() functionBrian2008-11-105-23/+33
|
* mesa: fix some misc breakage caused by editing auto-generated files rather ↵Brian Paul2008-11-101-4/+8
| | | | | | | | than the python generators Specifically: #include "glapitable.h" in src/mesa/main/glapi/dispatch.h Call _mesa_bsearch() in src/mesa/main/enums.c.
* GLX: fix out-of-bounds memory issue in indirect glAreTexturesResident()Brian Paul2008-11-101-4/+4
| | | | | | | | | | | | | | | | See bug 18445. When getting array results, __glXReadReply() always reads a multiple of four bytes. This can cause writing to invalid memory when 'n' is not a multiple of four. Special-case the glAreTexturesResident() functions now. To fix the bug, we use a temporary buffer that's a multiple of four bytes in length. NOTE: this commit also reverts part of commit 919ec22ecf72aa163e1b97d8c7381002131ed32c (glx/x11: Added some #ifdef GLX_DIRECT_RENDERING protection) which directly edited the indirect.c file rather than the python generator! I'm not repairing that issue at this time.

* mesa: remove calls to _mesa_adjust_image_for_convolution(), use texImage fieldsBrian Paul2008-10-231-14/+6
| | | | The texImage->Width/Height fields will have the post-convolution width/height.
* mesa: move convolution image adjustment code for glCopyTexSubImage1/2/3D()Brian Paul2008-10-221-15/+21
| | | | Do it after initial error checking, after we know the texture's internal format.
* mesa: some re-org of glCopyTexSubImage1/2/3D() error checkingBrian Paul2008-10-221-33/+32
|
* mesa: in textore.c, only adjust image for convolution if image is a color formatBrian Paul2008-10-223-14/+20
| | | | | Makes things consistant with the code in teximage.c. We only want to apply convolution to color formats (not depth/index formats)
* mesa: fix error codes in _mesa_GetObjectParameterivARB(), bug 17861Brian Paul2008-10-161-15/+6
|
* mesa: fix asst. issues in _mesa_texstore_argb8888()Brian Paul2008-10-101-40/+10
| | | | | | | | If we shift bytes into the texel word (or use the PACK_COLOR_8888 macro), we don't have to worry about big vs. little endian. See comments about texel formats in texformat.h. Remove an unneeded/incorrect else-if clause that produced wrong results on big-endian systems.

| | | | Fixes vtk crash and others.
* Unify ARB_depth_texture and SGIX_depth_textureIan Romanick2008-10-016-22/+16
| | | | | | | The ARB extension is a superset of the older SGIX extension. Any hardware that can support the SGIX version can also support the ARB version. In Mesa, any driver that supports one also supports the other. This unification just simplifies some bits of code.
* GLSL: Implement GL_OBJECT_TYPE_ARB queryIan Romanick2008-09-291-2/+10
| | | | | | | The GL_OBJECT_TYPE_ARB query is handled directly in _mesa_GetObjectParamterivARB because it is only supported in the extension version of the shanding language API. glGetProgramiv and glGetShaderiv should not accept this enum.
