Finds needed mesh part based on components relative positions (inside/outside) returns std::nullopt if given cuts do not divide origin mesh on good co

find squared distance from point Q to line segment Segm if Q projection point doesn't correspond to Segm segment, distance to Segm.a or Segm.b will be

Helper function to find own self-intersections on a mesh part

return the smallest index i>n such that bit i is NOT set, or npos if *this has no off bits.

finds an edge originated from v, which is located in the same triangle as p, and prev edge does not satisfy this property

Fork + exec @p exe with @p args. If @p detach, the child detaches into its own session and double-forks before exec so the grandchild has no parent in

constructs a matrix from its 3 columns; use this method to get the matrix that transforms basis vectors ( plusX, plusY, plusZ ) into vectors ( x, y, z

constructs a matrix from its 3 rows

returns whether we have already maximum number of elements stored

returns cached aabb-tree for points of this mesh, but does not create it if it did not exist

returns one of three face edges, closest to given point

returns one of three face edges, closest to given point

returns one of three face vertices, closest to given point

Whether we should draw this as a diameter instead of a radius.

returns the span containing all voxels

compute intervals of the slice which are projected on the selected area in the mesh (skip if not specified)
