The Crystal Space page has the official release of version 0.14 of this free 3D engine, now out of beta. Here's the rundown on C.S. from the page: "Crystal Space is a free (LGPL) and portable 3D engine written in C++. It supports true 6DOF, colored lights, mipmapping, portals, mirrors, alpha transparency, reflecting surfaces, 3D sprites, scripting, 8-bit, 16-bit, and 32-bit display support, Direct3D hardware acceleration on Windows, Glide and OpenGL hardware acceleration on Windows, Linux, OS/2, Macintosh, BeOS, ... See the extensive list of features for more details. Crystal Space currently compiles and runs on Linux, general Unix, Windows, Windows NT, OS/2, BeOS, NextStep, OpenStep, Rhapsody, DOS, Amiga, and Macintosh. It can optionally use Direct3D (Windows), GGI (Linux), Allegro (DOS), X11 (Unix/Linux) and SVGALIB (Linux). It can also optionally use assembler routines (GCC/DJGPP, Visual C++ and Intel only currently) and MMX if the processor supports it." Whew! Thanks Buzzy.
