Cleven was tested on SBCL and GNU/Linux. Memory mapped voxel maps on Windows are not supported, but this support is planned.
So far, it has a simple slice-based OpenGL renderer with an orthographic projection, basic support of volume sprites and a simple converter from polygonal models to voxel maps.
Depends on: alexandria, cl-fad, sb-cga, cl-sdl2, cl-opengl
