Inverse of model(s)UnderLoc?

[veganMalcontent]

I'd really like a function that returns the point in the image plane to which a
point on a 3D object will be projected. For instance, given a point on a
sphere in a 3D scene, what would be the _mouse.locH and _mouse.locV when then
mouse is directly over that point? For the inverse problem, we have
model(s)UnderLoc. But there doesn't appear to be a function for my problem.
Since 3D objects exist in a space for which there appears to be no linear
transform into the space of the image plane, I'm having trouble computing for
this point.

Any help would be greatly appreciated.

Check the worldSpaceToSpriteSpace() Lingo instruction.

Sweet, that does it. Thanks!
