Hi all,

I am new to the forums and new to Surface Evolver. I have an application in mind that I am sure is fairly trivial. I have two mesh models of shapes, call them "source" and "target". My hope was that I could register them in R^3 using some other algorithm and then look for the patches where the source shape differs from the target shape. In most cases this will be by some concave or convex patch on the source shape.

I would like to set up some sort of flow that takes the source shape and evolves it to the target shape (mean curvature flow?) and gives me a measure of the energy required to deform the source to the target.

Has anyone used S.E. for an application like this? Assuming that I can translate the meshes to .fe files, does anyone have any recommendations about how to perform the minimization?

Thank you in advance for any feedback!

I suppose I am basically asking if anyone has used a target shape to impose constraints on the final state of the evolution of another source shape that is a deformed version of the source and that flows from source to target?

Thanks!

Possibly with level set constraints?

Hello kjc,
Were you able to succeed in using SurfaceEvolver?
Could you translate meshes to .fe files?
I am also trying to learn surface evolver?
Can you share your experience in translating meshes to .fe files.


Thanks & Regards,

vidyadhar

Hi, did you find the way to translate the meshes into .fe files?
