But it really isn't practical in script/macro form. It would be too
slow, especially because you rarely have meshes with the same number of
vertices and faces. I think POV script is just too clumsy and slow to do
testellation (even non-adaptive) in an effective manner. It may cope OK
with a few thousand vertices, but an average mesh is ten times that.

There's something I've still have to try which is morphing between two Poser
meshes, for instance two meshes of the same character but with different poses.
The number of triangles would be slightly different but I guess they would be
more or less at the same "place" (foot, head etc.). Even if it wouldn't be a real
smooth morph, the effect of having little triangles flying around and taking
shape could be cool.

I was just thinking that an unusual type of morphing would be just moving
the csg primitives to their new location so as to turn one object into
another. Say your computer into a refrigerator...
Disk drive button turns into the handle, small cylinders that rounded the
corners a little grow into larger ones. Scale changes, texture changes,
mousepad turns into a tile floor...
In some changes it might be more TransFormer(tm) than Morph, but that might
be cool.
Not that I have the time or patience to do that...

Ooohh, I've been looking for a way to do this. Could you please write the
entire formula for doing this? TIA

My solution:
y*(x^2+z^2-1)+(1-y)*(max(abs(x), abs(z))-1) threshold 0
Gilles':
(abs(x)+abs(z))*(1-y)+(x^2+z^2)*y threshold 1
(From the french ng where this question appeared a few weeks ago)
