Houdini 16.5 Nodes VOP nodes

Tetrahedron Adjacent VOP node

Returns vertex indices of each face of a tetrahedron.

This operator allows you to determine which vertices of a tetrahedron form each of the four triangles of the tetrahedron.

Returns -1 if an invalid number is specified.

Returns 0 to 3 to refer to the four vertices of a generic tetrahedron.


Input Geometry

Disk file to read for the geometry. Can be op:/obj/object/soppath to read live SOP geometry.

Face Index

The face on the tetrahedron. Face 0 is the triangle that doesn’t have vertex 0.

Triangle Vertex

Which vertex on that face’s triangle to retrieve, 0..2.
