intersection_ray_mesh

compas.geometry.intersection_ray_mesh(ray, mesh)

Compute the intersection(s) between a ray and a mesh.

Parameters:

raytuple of point and vector

A ray represented by a point and a direction vector.

meshtuple of vertices and faces

A mesh represented by a list of vertices and a list of faces.

Returns:

list of tuple

Per intersection of the ray with the mesh:

0. the index of the intersected face

1. the u coordinate of the intersection in the barycentric coordinates of the face

2. the u coordinate of the intersection in the barycentric coordinates of the face

3. the distance between the ray origin and the hit
