improved performance if ray-tracing available
improved performance for face search -- some debugging required
works as well if no ray tracing available
method to check if points is inside cell
fixed bc check problem -- thought that was done already
added longest length
ported old-style projection
works without ray tracing as well now
skeleton for automatic plane filling (e.g. symmetry planes)
added macro for large real number
improved octree refinement -- still not reliable
added files for plane filling
mesh quality is only evaluated only for edge sharpening
faces have to be green for normal vector to be correctly oriented
new tool to create symmetry planes (ans similar planes) automatically
