cgalv2m gets stuck

[artturuohola]

I'm trying to use function [node,elem,face]=cgalv2m(vol,opt,maxvol,method) to mesh a uint8 volume that I have attached.

nested_sphere.zip

I'm using the following input

[node,elem,face]=cgalv2m(nested_sphere,[],100,'cgalmesh')

The code gets stuck and this is printed in console:

Mesh sizes are (label=size) (1=1.64834e+009)

you used (label=size) incorrectly. The size is not the maximum number of nodes, but the maximum volume in cubic voxels. Usually, you use something like 50, 100 etc.

okay

If my volumetric image has three grayscale values and I want all of the meshes to have maximum element volume of 100, what do I put in the "opt"?

[node,elem,face]=cgalv2m(nested_sphere,opt,'label1=100:label2=100:label3=100' ,'cgalmesh')

Is that correct?

have you looked this example in the sample folder? https://github.com/fangq/iso2mesh/blob/master/sample/demo_label_sizing.m#L33
