Shrink wrap mesh?

[oqilipo]

Hello

My question is if something similar could be done with this toolbox?

There is a function in Materialise Magics to Shrink Wrap a mesh: You can define:

• Sample Interval [mm]
• Gap Fill [mm]
• Organic Shape [True/False]
• Add extra thickness [mm]

Here is an example: Original: Shrink Wrap with 2mm Sample Interval, 20mm Gap Fill and Organic Shape True:

Thanks in advance oqilipo

I'm not sure exactly what Materialise Magics is doing. If I had to guess, it would be that they're using the closing operation. You can get an approximate closing very easily using the signed_distance_isosurface function in Matlab.

% parameter controlling gap size to merge
sigma = 0.5;
% Dilate original
 [V1,F1] = signed_distance_isosurface(V,F,'Level',sigma);
% Erode dilation
 [V2,F2] = signed_distance_isosurface(V1,F1,'Level',-sigma);

You'll have to play around with the parameters of signed_distance_isosurface.

Here's an animation I made using this type of closing for various sigmas.

Looks promising. I will play around with the parameters.

Thanks a lot!
