Hi All,
I’m quite new to Blender so I am struggling with the following problem - any help at all would be much appreciated!!
I have a .stl file captured using a 3D camera which I have imported into blender. I’m capturing various things, but basically it is always a curved convex or concave surface with an irregular object on top. For example, a lump of clay on the back of a hand. The 3D camera (as I’m sure you’re all already aware) creates a sort of surface “cast” of the scene.
Aim: I want to be able to measure the volume of that clay taking into account the curvature of the hand. The problem being that the surface the clay is on cannot be scanned beforehand and subtracted!
From what I gather I would need to somehow “intrude” the clay to actually create a volume to measure (perhaps measured using the 3D printer tools that come pre-packed with blender). But, I need to somehow do this so that the base of the clay is curved, as it is on the back of the hand, not a straight plane.
The eventual dream (and it is still very much a dream!), is to write a script in python that would take a user defined area (the edges of the clay) and use the surrounding cm or so of surface to predict the surface underlying the clay/extrude the “cast” of the clay down to that surface and measure the volume of the clay.
Thanks again for any help!
