Raster3D is a set of powerful tools for generating high quality raster images of proteins or other molecules. The core program renders spheres, triangles, cylinders, and quadric surfaces with specular highlighting, Phong shading, and shadowing. It uses an efficient software Z-buffer algorithm that is independent of any graphics hardware.
Seg3D is a volume editing and processing tool that combines a flexible manual segmentation interface with powerful higher-dimensional image processing and segmentation algorithms from the Insight Toolkit. DICOM, VFF, META, NRRD, and many other volume formats are supported. Users can explore and label image volumes using configurable, orthogonal slice view windows and 3D volume rendering.
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.
