GLC-Player GLC_Player is a OpenGL Open Source 3D viewer used to view 3d models (COLLADA, 3DXML, OBJ 3DS STL OFF COFF Format) and to navigate easily in these models.

The Open Source STL viewer (no update since 2004) Viewstl is an open source way to view Stereo Lithography Files as shaded on-screen images. Ascii STL files and dynamic rotation, scaling, and panning are currently supported. Written in C using OpenGL, GLU and GLUT.

STL Viewer (last Upd. 2010-01-23) Display and manipulate the content of stereolithography or STL files.
