__init__( quad_vertex_indices, positions, build_bvh=False, temporary_store=None, )[source]#

Constructs a D-dimensional quadrilateral mesh.

Parameters:

quad_vertex_indices (array) – warp array of shape (num_tris, 4) containing vertex indices for each quad, in counter-clockwise order
positions (array) – warp array of shape (num_vertices, D) containing the position of each vertex
temporary_store (TemporaryStore | None) – shared pool from which to allocate temporary arrays
build_bvh (bool)
