Animation Techniques in BRL-CAD
Abstract
Complex model systems can be difficult to depict using static images. Some phenomena are not apparent when viewed at a single instance in time. Many such things become much clearer, easier to detect and understand when they can be presented as moving, changing, evolving entities. For this reason, a set of tools have been created to help users generate motion picture sequences of systems modeled with BRL-CAD. Raytracing is a fundamental analysis and rendering technique within BRL-CAD. Most users of BRL-CAD are acquainted with the use of the program 'rt' for creating still images. A relative few understand how to utilize its capabilities for generating animation sequences or 'movies.' This paper introduces some of the tools and techniques available for creating animation sequences with 'rt' A basic knowledge of BRL-CAD, the geometry editor 'mged' and image creation using 'rt' is assumed.
