OpenGLUT is an open source project to evolve the GLUT API. It uses the FreeGLUT code base as a foundation for extending, enhancing, and refining the library interface. The initial goal is to define and implement OpenGLUT API Version 1.0, which is intended to supercede the GLUT 3.x API.
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.
