How can I convert STL file into stacks of 2D images?

I have a 3D STL file that I'm wishing to convert into a stack of 2D images for further image processing. Is there a matlab function capable of doing that?

Laziest and slowest way of doing this, but probably the most surefire way, is to use a scattered interpolant. Depending on the type of your STL file, you may have to generate data points with 0 values on locations that are empty.

First find the interpolant: scatteredInterpolant. Then query it at equispaced grid points you generate by using meshgrid.
