Three-dimensional interactive graphics for displaying and modelling microscopic data

EUCLID is a three-dimensional (3D) general purpose graphics display package for interactive manipulation of vector, surface and solid drawings on Evans and Sutherland PS300 series graphics processors. It is useful for displaying, comparing, measuring and modelling 3D microscopic images in real time. EUCLID can assemble groups of drawings into a composite drawing, while retaining the ability to operate upon the individual drawings within the composite drawing separately. EUCLID is capable of real time geometrical transformations (scaling, translation and rotation in two coordinate frames) and stereo and perspective viewing transformations. Because of its flexibility, EUCLID is especially useful for fitting models into 3D microscopic images.
