Polyhedron

Polyhedron(medium, vertices, triangles)

Triangulated volumetric object.

Args

• medium (MediumType): Tidy3D medium used in this structure.
• vertices (Sequence[Sequence[float]]): Vertices of the polyhedron. Each element must be a sequence of 3 coordinates.
• triangles (Sequence[Sequence[int]]): Sequence of triangles that make up the boundary mesh of the polyhedron. Each element is a sequence of 3 indices into the vertices sequence.

Note

The order of the indices in each triangle determine the outwards normal of the polyhedron at that triangle in the counter-clockwise direction. All normals must be set correctly.
