I am novice lacking professional terminology.

I want to create from 3D object (let's say from polygon mesh) a slice through to PNG file in order to create something like reverse medical MRI scan from which volumetric renders are created.

How it's called? It will enable me to find methods of achieving it. Bonus points for pointing to a library doing that.

  • $\begingroup$ MRI produces slices from volumetric data, your surface to slice conversion will just produce a flat slice with nothing remarkable inside the boundary. Granted, you can do that - just find the intersection of a slicing plane with all of your triangles, then assemble the resulting polygon. $\endgroup$ – lightxbulb Apr 22 at 10:20

Some terminology: Intersection of a polyhedron with a plane.

I just answered the question: How to build a 3d model from 2d pictures

and the answer is applicable here. In short, to build wiremesh from the 2d slice, you can take a look marching cube method. In this case you need to assume (or provide) the thickness of each pixel (hence a voxel) so that the MC algorithm can work. ITK/VTK should have some implementation for that.

The term could be called: 3d mesh reconstruction from volumetric data
