// TRIM_WITH_SOLID Given an arbitrary mesh (VA,FA) and the boundary mesh
|
|
// (VB,FB) of a solid (as defined in [Zhou et al. 2016]), Resolve intersections
|
|
// between A and B subdividing faces of A so that intersections with B exists
|
|
// only along edges and vertices (and coplanar faces). Then determine whether
|
|
// each of these faces is inside or outside of B. This can be used to extract
|
|
// the part of A inside or outside of B.
|
|
//
|
|
// Inputs:
|
|
// VA #VA by 3 list of mesh vertex positions of A
|
|
// FA #FA by 3 list of mesh triangle indices into VA
|
|
// VB #VB by 3 list of mesh vertex positions of B
|
|
// FB #FB by 3 list of mesh triangle indices into VB
|
|
// Outputs:
|
|
// V #V by 3 list of mesh vertex positions of output
|
|
// F #F by 3 list of mesh triangle indices into V
|
|
// D #F list of bools whether face is inside B
