sci ePiX creates mathematically accurate figures, plots, and movies using easy-to-learn syntax. The output is expressly suitable for use with LaTeX; figures may be written in a LaTeX picture environment containing PSTricks, tikz, or eepic macros, or as vector (EPS or PDF) image files. The user interface resembles that of LaTeX: You prepare a human-readable scene description in a text editor, then compile the input file into a picture. use ePiX, however.
