Detailed Description

Laplacian to smoothly deform a region preserving mesh fine details. How to use:

1. Initialize Laplacian for the region being deformed, here region properties are remembered.
2. Change positions of some vertices within the region and call fixVertex for them.
3. Optionally call updateSolver()
4. Call apply() to change the remaining vertices within the region Then steps 1-4 or 2-4 can be repeated.
   Generated from class MR::Laplacian.

Generated from class MR::Laplacian. Heap-allocated instances are held in Owned<Laplacian>.
