It provides interactive control for motion, appearances +(including lighting, shading, and materials), picking on an +object, edge or vertex level, snapshots in SGI image file or +Renderman RIB format, and adding or deleting objects is provided +through direct mouse manipulation, control panels, and keyboard +shortcuts. External programs can drive desired aspects of the +viewer (such as continually loading changing geometry or +controlling the motion of certain objects) while allowing +interactive control of everything else. + +Geomview supports the following simple data types: polyhedra with +shared vertices (.off), quadrilaterals, rectangular meshes, +vectors, and Bezier surface patches of arbitrary degree including +rational patches. Object hierarchies can be constructed with +lists of objects and instances of object(s) transformed by one or +many 4x4 matrices. Arbitrary portions of changing hierarchies +may be transmitted by creating named references. |
