Webtrimesh.ray.ray_triangle. A basic slow implementation of ray- triangle queries. An object to query a mesh for ray intersections. Precomputes an r-tree for each triangle on the mesh. Check if a mesh contains a list of points, using ray tests. If the point is on the surface of the mesh the behavior is undefined. WebUse the antenna.Triangle object to create a triangular shape in the X-Y plane with one vertex at the origin.
