Literacy

• Learn by doing
  • Take away a sound understanding of new concepts learned at the end of each activity
  • Transform knowledge into intuition
  • Share your learnings
  • Experiment to avoid/overcome procrastination

;; Tetrahedron intersection based on this paper & algorithm:
;; http://vcg.isti.cnr.it/Publications/2003/GPR03/fast_tetrahedron_tetrahedron_overlap_algorithm.pdf
;;
;; Unlike original algorithm this implementation produces correct
;; results regardless of the orientation/ordering of points defining
;; the two tetrahedra. This is achieved via the orient-tetra function,
;; which ensures the correct ordering of vertices for this algorithm
;; to function properly.
;;
;; Implementation extracted from upcoming geometry library
