Is there such a thing as a Math plugin for Blender or another 3D program
Do you know of a software or plugin to solve this problem? I have a 3D sculpt of a figure made out of digital clay. It doesn't have a texture map (so I can't unwrap it and get flat "gift wrap", although this is exactly what I need.) I'm trying to find the length of lines on the actual figure, so for example the circumference of the head. It's just calculus, right, so theoretically it would be easy to find? Has someone made such a "math" plugin for these types of sculpting programs, where I just trace a line and it gives me the length? Or is there an easier way to solve this problem?

@lewis2e YES! Ok, this is totally what I want.
There's no way to wrap the entire figure with a texture map and then unwrap it so it's flat, is there? Like, in the picture below, all the lines are technically straight, but only when it's a sphere.
You're a lifesaver. Now to learn terminal. :)

bbymightywaterways Good to hear.
Erm... I'm not sure that I completely understand what you are asking re: the UV unwrap. I might need some more detail there.
You can unwrap your model in a number of ways, it's just about where you put the seams. Placing the seams correctly so that you unwrap your 3D model to a nice, consistent 2D shape is the aim of the game for UV unwrapping... and is kind of a skill in itself.

sstatus451_cg Sorry, I know just enough Blender to know that I will never ever learn all that it can do. :) Ok, I will try to tackle it from the python/math angle. You guys have been a great help.
