Polyhedron

class photonforge.Polyhedron(medium, vertices, triangles)

Triangulated volumetric object.

Parameters:

• medium – Tidy3D medium used in this structure.

• vertices – Vertices of the polyhedron. Each element must be a sequence of 3 coordinates.

• triangles – 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.

Methods

copy()	Create a copy of this 3D structure.
to_tidy3d()	Create a Tidy3D structure from this polyhedron.
write_ply(filename)	Output this plyhedron's mesh to a PLY file.

Attributes

medium	Polyhedron medium.
triangles	Indices of vertices for each triangle in the polyhedron surface.
vertices	Vertices of the polyhedron.
