I wanna know role of projection

What is role of projection in wrapx?

please tell me more.

The common use-case is when you want to produce highly detailed morph-targets, but wrapping a high-poly model onto a scan might take too long.

In this case you

  1. Wrap a low-poly basemesh onto a set of scans,
  2. Subdivide the set of wrapped basemeshes several times so that they become high-poly,
  3. Project each basemesh onto corresponding scan.

As a result you have a set of morph-targets that shares the same vertex-order and reproduce fine details of the original scans.

Thank you for reply Andrew.

I fully understand.
