Most of 39 the work was done by Michal Krol. 40 There's probably a fair number of bugs since this is a pretty large, 41 complicated body of code. 42 <br> 43 The OpenGL 2.0 interface to these features will be implemented in a 44 future version of Mesa, 45 46 <li>GL_EXT_timer_query 47 <br> 48 Used to measure the time of OpenGL operations at high precision. 49 Only supported in the software/Xlib driver at this time. 50 51 <li>GL_EXT_packed_depth_stencil 52 <br> 53 Defines a new GL_DEPTH_STENCIL_EXT pixel format. 54 55 <li>GL_EXT_framebuffer_blit 56 <br> 57 A simplified glCopyPixels-like feature for copying pixel rectangles. 58 59 <li>GL_ARB_half_float_pixel 60 <br> 61 Adds a new half-precision floating point format for image transfers, 62 such as for glDrawPixels, glReadPixels, glTexImage, etc. 63 </ul> 64 65 <h2>Changes</h2> 66 <ul> 67 <li>removed GL_HP_occlusion_test (use GL_ARB_occlusion_query instead) 68 <li>removed GL_SGIX/SGIS_pixel_texture extensions 69 </ul> 70 <h2>Bug fixes</h2> 71 <ul> 72 <li>fixed glxcontextmodes.c datatype problem (bug 5835) 73 <li>fixed aix-gcc build/install bugs (bug 5874) 74 <li>fixed some bugs in texture env program generation 75 <li>glXCopyContext() didn't handle texture object bindings properly 76 <li>glXCopyContext() didn't copy all lighting state 77 <li>fixed FreeBSD config (Pedro Giffuni) 78 <li>fixed some minor framebuffer object bugs 79 <li>replaced dprintf() with _glu_printf() in GLU (bug 6244) 80 <li>fixed a number of thread safety bugs/regressions 81 <li>fixed a number of GLU tesselator bugs (John Shell, bug 6339) 82 <li>paletted texturing was broken w/ floating point palettes (K. Schultz) 83 <li>lots of assorted framebuffer object bug fixes 84 </ul> 85 86 87 <h2>Known Issues</h2> 88 <ul> 89 <li>Rendering to depth textures will not work. Rendering to GL_DEPTH_STENCIL 90 textures should work. 91 </ul> 92 93 94 <h2>Driver Interface Changes</h2> 95 <ul> 96 <li>Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by 97 the two-sided versions: Driver.Stencil*Separate(). 98 <li>Render-to-texture: The functions for rendering to textures have changed. 99 </ul> 100 101 102 <h2>To Do (someday) items</h2> 103 <ul> 104 <li>Switch to freeglut 105 <li>Increase MAX_DRAWBUFFERS 106 <li>Fix linux-glide target/driver. 107 <li>Fix lambda calculation for frag progs. 108 </ul> 109 110 111 <h2>Driver Status</h2> 112 113 <pre> 114 Driver Status 115 ---------------------- ---------------------- 116 DRI drivers varies with the driver 117 XMesa/GLX (on Xlib) implements OpenGL 1.5 118 OSMesa (off-screen) implements OpenGL 1.5 119 Glide (3dfx Voodoo1/2) implements OpenGL 1.3 120 SVGA implements OpenGL 1.3 121 Wind River UGL implements OpenGL 1.3 122 Windows/Win32 implements OpenGL 1.5 123 DJGPP implements OpenGL 1.5 124 GGI implements OpenGL 1.3 125 BeOS implements OpenGL 1.5 126 Allegro needs updating 127 D3D needs updating 128 </pre> 129 130 </body> 131 </html> 132
