The libfixgl project begins! |
Welcome to the brand-new libfixgl project web page!
libfixgl, is an implementation of the OpenGL standard for realtime 3D
graphics, based on fixed point arithmetic. Apart from doing all the internal
mathematics (such as transformations, lighting, and rasterization) in fixed point
arithmetic, it also provides alternative API entry points using fixed point
arguments. Of course the regular floating point interface is still there too,
acting as wrappers for the fixed point functions. So for example there are both a
glVertex3f function and a new fixed point version called
glVertex3x
The objective of this project is to produce a full-featured, fast, and usable
implementation of OpenGL for handheld consoles such as the GP2X, GP32, GBA, or
other FPU-less embedded devices. However you are free to use it anywhere you see
fit, since the code is completely platform-independent ANSI/ISO C.
If you are interested in contributing a patch to the project, make sure you
have checked out the latest SVN snapshot (svn co
https://svn.sourceforge.net/svnroot/libfixgl ), and do send me an email to let me
know what you will be implementing. An grossly incomplete list of tasks to be
done is available at the sourceforge project page
