Quesa is a high-level open-source 3D graphics library that offers binary and
source level compatibility with Apple's QuickDraw™ 3D API. Quesa does not
contain any Apple source code, and was developed without access to Apple's
QD3D implementation.
Quesa supports both retained and immediate mode rendering, an extensible file
format, plug-in renderers, a wide range of high level geometries, hierarchical
models, and a consistent and object-oriented API. Quesa acts as a scene-graph
while using OpenGL for rendering.
