warp.mesh_get

warp.mesh_get(id: uint64) → Mesh

Kernel

Retrieve the warp.Mesh object identified by id.

Example

@wp.kernel
def first_face_vertex(mesh_id: wp.uint64, out: wp.array[wp.vec3]):
    m = wp.mesh_get(mesh_id)
    # the returned struct exposes the mesh arrays (points, indices, velocities)
    out[0] = m.points[m.indices[0]]  # position of the first face's first vertex

points = wp.array([[0,0,0],[1,0,0],[1,1,0],[0,1,0],[0,0,1],[1,0,1],[1,1,1],[0,1,1]], dtype=wp.vec3)
indices = wp.array([0,3,2, 0,2,1,  4,5,6, 4,6,7,  0,1,5, 0,5,4,
                    2,3,7, 2,7,6,  0,4,7, 0,7,3,  1,2,6, 1,6,5], dtype=wp.int32)
mesh = wp.Mesh(points=points, indices=indices)

out = wp.zeros(1, dtype=wp.vec3)
wp.launch(first_face_vertex, dim=1, inputs=[mesh.id], outputs=[out])
print(out.numpy()[0])
