3d convex hull associated to a shape
Convex Hull 3d measure is the direct extension of the [Concept] Convex Hull 2d measure.
Like in 2d case, if the shape contains holes, they are deleted and the convex hull does not contain the holes.
Here is an example of the convex hulls calculated on the shapes extracted from the 3d test image MorphoBin3d6.tif :
