This paper presents a pedagogical introduction to the issue of how implement Lorentz transformations in relativistic visualization. The most efficient approach is use even geometric algebra 3+1 spacetime dimensions, or equivalently complex quaternions, which are fast, compact, and robust, straightforward compose, interpolate, spline. has been incorporated into Black Hole Flight Simulator, an in...

Procedural models (i.e. symbolic programs that output visual data) are a historically-popular method for representing graphics content: vegetation, buildings, textures, etc. They offer many advantages: interpretable design parameters, stochastic variations, high-quality outputs, compact representation, and more. But they also have some limitations, such as the difficulty of authoring procedural...
