Class IndexedTriArray

  • public class IndexedTriArray
extends TriMesh
    this class is a proxy to a triangle mesh where the triangles
    can be indirectly copied in an efficient manner.

    Each "virtual" triangle index is mapped to the actual triangle index.
    By rearanging the mapping the order of the triangles in the mesh are
    rearanged to the proxy user, without changing the actual triangle mesh.

        public IndexedTriArray​(long cPtr,
                       boolean cMemoryOwn)

      • IndexedTriArray

        public IndexedTriArray​(TriMeshPtr objArr)
        constructor - creates a proxy that initially maps triangles
        from [0:0,1:1,2:2,....,i:i]
        Parameters:
        objArr - [in] the triangle mesh on which to create a proxy

      • IndexedTriArray

        public IndexedTriArray​(TriMeshPtr objArr,
                       SWIGTYPE_p_rw__core__PtrT_std__vectorT_unsigned_long_t_t idxArr)
        constructor - creates a proxy where the initial mapping
        is determined by idxArr.

        idxArr must be same length as the number of triangles.

        Parameters:
        objArr - [in] the triangle mesh on which to create a proxy
        idxArr - [in] the index mapping
