TinyGL

a 3D render of multiple gears floating in empty space, one red, one blue, and one green.

This is an extension of Fabrice Bellard's TinyGL project.

TinyGL is an implementation of the OpenGL 1.2 specification in pure software, using no hardware acceleration. It is designed to be lightweight and fast, using highly optimized rasterization routines originally written by Fabrice Bellard.

The minimum requirements to compile & run this code is ISO C99 compliance and a 32-bit processor respectively.

TinyGL can also be installed as a system-wide library and then accessed with pkg-config.

The original versions (in .tar.gz format) can be found in the archive folder.
