Can I create various faces using reference 3d model?

General

Hi,
I have a 3d scanned head model.
Wrap3 could convert it to the good retopology model(A) using reference head model(B).

Now, there are many face patterns with reference head model(B1, B2, B3..Bn).
I’d like to make various face(A1, A2, A3…An) using them.

Writing in the formula,

If there are face functions,

B1 = function1(B)
B2 = function2(B)
:

I want to use this functions with other faces.

A1 = function1(A)
A2 = function2(A)
:

Do you know how to actualize that idea?

Thanks.

Hey, not sure if I get it correctly. Is B a lowpoly mesh or a scan? If B is a lowpoly base mesh and A is the same mesh wrapped onto some scan, then yes, having that mapping you can automatically map another base mesh B2 to the same scan. If both B and B2 have the same geometrical shape (and different topology), you can use a **Lattice node **(http://www.russian3dscanner.com/docs/Wrap3/Nodes/Lattice/Lattice.html) to deform B2 into A2 the same way as B was deformed to A.

Please let me know if that answers your question!

Thank you for reply.

Is B a lowpoly mesh or a scan? If B is a lowpoly base mesh and A is the same mesh wrapped onto some scan?

Let me explain exactly.
Yes it is. And B groups have many face patterns, like sad, happy, left eye closing, right eye closing,… etc.

So, I’d like to make A’s face patterns automatically.
This “automatically” is important for me. Because it’s too hard to make them by hand.

Should I try to use Lattice node for it?

Oh, I see. So you have a set of facial expressions for the basemesh B and want to transfer those expressions to a neutral mesh A. If A and B are in the same topology, you can use a Blendhsape node to do that. The process is shown in this video starting from 4:00

If A and B are in different topology, you can wrap A onto B’s neutral expression, then use a Lattice node to get the rest of the expressions in A topology. Then use the previous step.

Please let me know if it helps.

Wow! Super helpful!
I could make it great thanks to you!

Hey, looks very nice! Glad it works!
