Hi -- I'm sorry we didn't respond earlier, but NeXT mail is rather awkward for us to read. Anyway, the answer is very simple. Vertex indices from a "pick" message on an OFF primitive are exactly the same as the vertex indices you use in describing the faces in the OFF object: they're integers from 0 to <number of vertices in the OFF object> - 1. Likewise, faces are numbered in the order they appear in the OFF file, in the range from 0 to <number of faces in the OFF object> - 1. Stuart Levy
