given input edge (src), converts its id using given map

returns vector equal to edge destination point minus edge origin point

returns Euclidean length of the edge

return the smallest index i such that bit i is set, or npos if *this has no on bits.

computes angle-weighted sum of normals of incident faces of given vertex (only (region) faces will be considered); the sum is normalized before return

Appends given history action to viewer's global history store

returns coordinates of the edge destination

see https://arxiv.org/pdf/math/9410209 Table 4-i: a=(pi_i,1, pi_i,2) b=(pi_j,1, pi_j,2)

computes directed double area for a triangular face from its vertices

return real GL value for DepthFunction default is less or equal

returns coordinates of the edge origin

converts given point in double precision and applies given transformation to it

Adding a template parameter to avoid including the whole `imgui.h`.

returns squared Euclidean length of the edge (faster to compute than length)

computes intersection between this and other box
