I am trying to develop an algorithm inwhich I need to demonstrate a 3D area by a logical matrix (1 inside a surface, 0 outside). I have a surface shown as a series of points which are floating point coordinates. How can I fill in a shape inside a logical 3D matrix annotated by this surface?

Multiple ways:
  1. Use inpolygon, get indices, fill the logicals.
  2. Use ineqalities and get logicals straight away.

can you elucidate your answer by a few lines of code?

I have a 3d array of floating positions. How can I fill by logical operations while positions are not inside a single layer?!
