Quote - I think it's a bit premature, but I'll add that to give you something to play with... my concern is that you'll fixate on doing the Capsule mapping or something - which gave decent results in your earlier test (especially with closely aligned meshes, where the ray doesn't travel far), but will fall flat (as it were) for things like the top of the nostrils - the ray needs to head in a generally downward direction to hit the top of the nostril, but it's Cylindrical path (in that zone) will cause it to head sideways, instead (for example).

Many thanks, for adding the function!  :woot:  I promise not to fixate on one approach.  What this does, though, is open up the possibility of optional settings, both for development testing and for the final script.

What's needed now is more refined "steering" of the normals, not any kind of blanket approach like spherical or capsule-shaped normals.  That would be less refined.  The little test I posted was just to illustrate that one needn't be reliant on the existing normals of the mesh, as well as to illustrate that the main complaint I've long had about the Classic TDMT method is actually that very reliance on the existing paths of the normals.  What we basically end up doing here is using the closest vertices results to screen candidate tripolys and refine the paths of the normals for the raycasting.  Which is fantastic.  I wish we'd thought of something like this three years ago.  :lol:

I'm really glad to have you contributing to this again!  :woot:  But, again, don't let it interfere with any obligations you might have, if you're busy.
