Mesh deformation #265

Open SimonCald opened 1 year ago

SimonCald commented 1 year ago

We want to smoothly deform the mesh, either by pressing or pulling the surface of the model at certain points.

This will be done by computing a homothety function on nodes, the origin of the homothety is the plane Y=0. We also give a radius of smoothness for each deformation.

Branch issue-265-Mesh_deformation created!

SimonCald commented 1 year ago

The commit 3112bcdfb22616504eea574d6caf538bb4ba8153 give the first draft for the algorithm. By giving a mesh, a list of points and a radius the code the able to deform the mesh.

Next steps are:

1) the implementation of locked elements that will become the new local origin of the homothety function.
2) implementation of tangent morphing, for example applying a pressure on the model in Y axis will apply a pull in Z and -Z i.e. we try to simulate a volume conservation
