"Obliq-3D Tutorial and Reference Manual" Marc A. Najork December 1, 1994. 110 pages. Obliq-3D is an interpreted language that is embedded into the 3D animation system Anim3D. Anim3D is based on a few simple, yet powerful constructs that allow a programmer to describe three-dimensional scenes and animations of such scenes. Obliq-3D, by virtue of its interpretive nature, provides the programmer with a fast turnaround environment. The combination of simplicity and fast turnaround allows application programmers to construct non-trivial animations quickly and easily. The first half of this report contains a tutorial to Obliq-3D, which develops the various concepts of the animation system. The second part contains a reference manual, which describes the functionality of Obliq-3D module by module.
