returns this triangle with the opposite orientation

finds power of 2 that represents given msaa number ==log2(msaa)

computes the number of active point pairs

returns the number of nodes in the binary tree with given number of points

Get list of reference files for the test file. For file foo.bar it searches for foo_opt1.bar, foo_opt2.bar, etc. :param full_file_path: name

returns true if given vertex is on (region) boundary

return true if given edge is inner for given region (or for whole mesh if region is nullptr)

Reference cube used as mesh "a" in every case: edge length 4, centered on origin.

returns the number of pixels

prepares precise-coordinates for a vertex from the other mesh

runs `once` (returns elapsed ms) warmup+iters times, prints min/median/mean

if distance between the last point and the given one is more than critical distance we should make a transit on the safe height
