Download the OpenGL voxel object viewer (for Windows) :
VoxelV.zip (70 KB, updated July 1999)
10 voxel objects included
To enable all features of the viewer, use OpenGL version 1.1 or later.
VoxelV supports two different cameras: the polar camera to rotate and position the object, the fly camera to move around or enter the object. The cameras can be controlled using a mouse and keyboard interface.
A variety of rendering modes can be selected. Fog, lighting, texture, filtering, perspective correction, depth buffering, culling and dithering. Hardware accelerated OpenGL is not required, but strongly recommended.
