Edgewise subdivision of tetrahedron
This is the implementation of the algorithm by Edelsbrunner and Grayson [1] for
subdividing the tetrahedron in R^4 with vertices (1,0,0,0), (0,1,0,0),
(0,0,1,0), (0,0,0,1). Syntax: subd n, where n is a positive integer. [1] H. Edelsbrunner and D. R. Grayson, Edgewise subdivision of a simplex. DCG, 24:707--719, 2000. |
