Mesa's -simple off-screen rendering interface is completely operating system -and window system independent so programs which use off-screen -rendering should be very portable. This feature effectively -enables you to use Mesa as an off-line, batch-oriented renderer. -</p> -<p> -The "OSMesa" API provides 3 functions for making off-screen -renderings: OSMesaCreateContext(), OSMesaMakeCurrent(), and -OSMesaDestroyContext(). See the Mesa/include/GL/osmesa.h header for -more information. See the demos/osdemo.c file for an example program. -There is no facility for writing images to files. That's up to you. -</p> -<p> -If you want to generate large images (larger than 1280x1024) you'll -have to edit the src/config.h file to change MAX_WIDTH and MAX_HEIGHT -then recompile Mesa. Image size should only be limited by available -memory. -</p> - - -<H2>Deep color channels</H2> - -<p> - For some applications 8-bit color channels don't have sufficient - accuracy (film and IBR, for example). If you're in this situation - you'll be happy to know that Mesa supports 16-bit and 32-bit color - channels through the OSMesa interface. When using 16-bit channels, - channels are GLushorts and RGBA pixels occupy 8 bytes. When using 32-bit - channels, channels are GLfloats and RGBA pixels occupy 16 bytes. -</p> -<p> - To build Mesa/OSMesa with 16-bit color channels: -<pre> - make realclean - make linux-osmesa16 -</pre> - - For 32-bit channels: -<pre> - make realclean - make linux-osmesa32 -</pre> - -<p> -You'll wind up with a library named libOSMesa16.so or libOSMesa32.so. -</p> - -<p> -If you need to compile on a non-Linux platform, copy Mesa/configs/linux-osmesa16 -to a new config file and edit it as needed. Then, add the new config name to -the top-level Makefile. Send a patch to the Mesa developers too, if you're -inclined. -</p> - -<p> -BE WARNED: 16 and 32-bit channel support has not been exhaustively -tested and there may be some bugs. However, a number of people have -been using this feature successfully so it can't be too broken. -</p> - - -</BODY> -</HTML> |
