SLIDE: Scene Language for Interactive Dynamic Environments
(Computer Graphics)
SLIDE is a "language for describing and interacting with hierarchical, dynamic environments". It is mainly a teaching tool for undergraduate Computer Graphics courses, similar to Nachos for Operating Systems. It re-implements many of the details of OpenGL such as bound clipping, scan-line processing, z-buffering, Gouraud shading, ad nauseam.
A SLIDE model is composed of geometry, lights, and cameras. These components are placed together in a directed-acyclic graph, called a scene graph through grouping and instancing.
It used to be called GLIDE (G="Graphics") until 3dFX trademarked it and sued over the name. But look who's around now... 3dFX/GLIDE or Berkeley/SLIDE?
