How can I calculate the volume enclosed by an isosurface, in this case my isosufaces are generally irregular cylinders.
I've attached an image to give you and idea of the tubes (although its not a great one!)
Convex hull method over estimates due to its curvature, but could possibly work for small segments and summation over the whole tube. However, there must be a simpler way!?
Many thanks, Will

Cleaned up image and counted the data points which represent voxels (of known value)..... easy

Hey William,
I am just doing the same thing, was that as much as you did? I want an area/volume ratio for my isosurfaces, doesn't seem to be any nice algorithm for calculating volume. I will try your method and just multiply that by the voxel size I guess, see how that works out.
thanks,
William

Hej William,
May I ask you got success previously in getting volume of the isosurfaces? Thanks
