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 90textures 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Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by 97the two-sided versions: Driver.Stencil*Separate(). 98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> 114Driver Status 115---------------------- ---------------------- 116DRI drivers varies with the driver 117XMesa/GLX (on Xlib) implements OpenGL 1.5 118OSMesa (off-screen) implements OpenGL 1.5 119Glide (3dfx Voodoo1/2) implements OpenGL 1.3 120SVGA implements OpenGL 1.3 121Wind River UGL implements OpenGL 1.3 122Windows/Win32 implements OpenGL 1.5 123DJGPP implements OpenGL 1.5 124GGI implements OpenGL 1.3 125BeOS implements OpenGL 1.5 126Allegro needs updating 127D3D needs updating 128</pre> 129 130</body> 131</html> 132
