How to calculate the thickness of a mesh
I have models of some helmets that were laser scanned inside and out to create a full representation. I would like to create a texture for the mesh of each that represents the thickness of the helmet, somewhat like a 'heatmap' for thickness. I realize the calculation of thickness is not straightforward, but what I'm looking to calculate is the thickness of the metal of the helmet.
Can anyone please recommend a software/workflow which can be used to achieve this? Open source preferred, currently using Blender, Meshlab, and Slice 3D, but will use whatever is necessary.
MeshLab has the Shape Diameter Function that computes what is a good generic definition of the thickness of a mesh. For an example of its usage, follow this example inside MeshLab (each line one filter):
- create a sphere (subdiv lev 2)
- apply random displacement to vertexes (displacement 2%)
- apply loop subdivision (3 iter) to get a smooth wavy sphere)
- create another smaller smooth sphere (radius 0.9, subdiv 5)
- invert this sphere
- flatten the two layers into a single mesh (at this point you have a single mesh composed by two concentric spheres, one inside, perfectly round and one outside wavy)
- apply Shape Diameter function (256 sample, 60 degree cone radius)
- apply Colorize by vertex quality
The result is encoded in quality and here you see it mapped into color; you can see how thicker regions correctly correspond to larger quality values.
