313 6733 d 19 h jrf /trunk/ BSPTree ray tracing now works well !
The problem was a way too large epsilon causing triangles to appear unnecessarily in several different space division boxes. Precision has now been increased and the code has been made more robust. Try it out on the bunny.

191 7096 d 1 h jab /trunk/ So some changes have been made. Things are partly foobar in the volume
polygonizer and the trilinfilter. There is a dilemma - it is hard to
allow trilinear interpolation of vectors while disallowing gradient
computation of unsigned entities.
