class warp.fem.Quadmesh3D(
quad_vertex_indices,
positions,
build_bvh=False,
temporary_store=None,
)[source]#

Three-dimensional quadrilateral mesh.

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

Construct 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)
