MultiSlice RTP is a radiotherapy treatment planning and medical image processing system developed for Silicon Graphics MIPS architecture systems and the IRIX operating system (5.3 and above). It allows you to manipulate upto 20 2D CT image slices as one 3D slice and run bulk batch processing algorithms on the images loaded. Written in C and linked against the MOTIF toolkit, it also runs on Xfree/Linux/Lesstif and can load RAW CT images from a CT scanner directly.
Obsidian is an extensible virtual world system with a fullblown multiplayer client-server architecture. It is not a VRML2 world system, though there are plans to include VRML2 as a world data format. Note that active development on this system stopped a while ago, though the code is still available for the curious. The code may not even compile on current Linux or Irix systems.
