Most of 28 the work was done by Michal Krol. There's probably a fair number of 29 bugs since this is a pretty large, complicated body of code. 30 31 The OpenGL 2.0 interface to these features will be implemented in a 32 future version of Mesa, 33 34- GL_EXT_timer_query 35 36 Used to measure the time of OpenGL operations at high precision. Only 37 supported in the software/Xlib driver at this time. 38 39- GL_EXT_packed_depth_stencil 40 41 Defines a new GL_DEPTH_STENCIL_EXT pixel format. 42 43- GL_EXT_framebuffer_blit 44 45 A simplified glCopyPixels-like feature for copying pixel rectangles. 46 47- GL_ARB_half_float_pixel 48 49 Adds a new half-precision floating point format for image transfers, 50 such as for glDrawPixels, glReadPixels, glTexImage, etc. 51 52Changes 53------- 54 55- removed GL_HP_occlusion_test (use GL_ARB_occlusion_query instead) 56- removed GL_SGIX/SGIS_pixel_texture extensions 57 58Bug fixes 59--------- 60 61- fixed glxcontextmodes.c datatype problem (bug 5835) 62- fixed aix-gcc build/install bugs (bug 5874) 63- fixed some bugs in texture env program generation 64- glXCopyContext() didn't handle texture object bindings properly 65- glXCopyContext() didn't copy all lighting state 66- fixed FreeBSD config (Pedro Giffuni) 67- fixed some minor framebuffer object bugs 68- replaced dprintf() with \_glu_printf() in GLU (bug 6244) 69- fixed a number of thread safety bugs/regressions 70- fixed a number of GLU tesselator bugs (John Shell, bug 6339) 71- paletted texturing was broken w/ floating point palettes (K. Schultz) 72- lots of assorted framebuffer object bug fixes 73 74Known Issues 75------------ 76 77- Rendering to depth textures will not work. Rendering to 78 GL_DEPTH_STENCIL textures should work. 79 80Driver Interface Changes 81------------------------ 82 83- Stencil: The Driver.StencilOp/Func/Mask() functions have been 84 replaced by the two-sided versions: Driver.Stencil*Separate(). 85- Render-to-texture: The functions for rendering to textures have 86 changed. 87 88To Do (someday) items 89--------------------- 90 91- Switch to freeglut 92- Increase MAX_DRAWBUFFERS 93- Fix linux-glide target/driver. 94- Fix lambda calculation for frag progs. 95 96Driver Status 97------------- 98 99:: 100 101 Driver Status 102 ---------------------- ---------------------- 103 DRI drivers varies with the driver 104 XMesa/GLX (on Xlib) implements OpenGL 1.5 105 OSMesa (off-screen) implements OpenGL 1.5 106 Glide (3dfx Voodoo1/2) implements OpenGL 1.3 107 SVGA implements OpenGL 1.3 108 Wind River UGL implements OpenGL 1.3 109 Windows/Win32 implements OpenGL 1.5 110 DJGPP implements OpenGL 1.5 111 GGI implements OpenGL 1.3 112 BeOS implements OpenGL 1.5 113 Allegro needs updating 114 D3D needs updating 115
