Boolean operations

Methods

Name	Syntax	Description
bool	Result = mesh:bool(othermesh:TLUAMesh; operationtype:integer)	Bools the current mesh with a another. Operationtype 0 adds the mesh, 1 subtracts it.
insertselfintersections	mesh:insertselfintersections(epsilon:number)	Replaces a mesh with itself but split along its self-intersections.
intersect	mesh:intersect()	Replaces a mesh with the Boolean intersection of its shells
unify	mesh:unify(epsilon:number)	Replaces a mesh with the Boolean unification of its shells. Tip: To subtract a shell, invert it before unifying. epsilon is mandatory for legacy reasons, but its actual value is ignored internally. It used to be a tolerance.
wrap	mesh:wrap()	Replaces a mesh with the wrap of its shells: Discards any internal surfaces, fully enclosed or created by self-intersections alike. Uses a parallel multicore algorithm.
wrapsinglecore	mesh:wrapsinglecore()	Replaces a mesh with the wrap of its shells. Uses the old singlecore algorithm.

Name	Example	Return value
unify	found_self_intersections = mesh:unify(0.05)	Boolean: Returns true if any self-intersections were found (or whether they were disregarded due to the epsilon value). With very intricate meshes, this function may create many small shells which should be trimmed using "removeghostshells"
intersect	found_self_intersections = mesh:intersect()	Boolean: See unify
insertselfintersections	found_self_intersections = mesh:insertselfintersections(0.05)	Boolean: Returns true if any self-intersections were found (or if they were disregarded due to the epsilon value). Attention: This function may create a lot of shells, but it can orient not-orientable surfaces.
wrap	mesh:wrap()	-
