Given 1. a mesh 2. two planes 3. two mesh edges, each intersected by corresponding plane, with org(ei) and dest(ei) in negative and positive parts of

obtains coordinates of unique points in the order of vertex ids

obtains triangulation with vertex ids

computes trace of the matrix

returns the number of allocated undirected edges (pairs of half-edges)

unites the two sets containing given elements WITHOUT balancing by set size (BaseUnionFind keeps no sizes): it simply attaches one set's root under th

returns true if given two elements are from one set

gets object visibility as bitmask of viewports

Adds any element type of `ElemVar`.

adds to this squared distance to line passing via origin with given unit direction

amount of precipitation (in same units as mesh coordinates and water level), which can be added before overflowing the basin

circle of n points (closed: first == last)

bidirectional distance from input location to mtp considering point's weight
