Eliminate vertices outside of multiple convex hulls

Goal: Eliminate vertices outside of multiple 3D cubes.

Here's what I currently have in the prerequisites.

Prerequisites - Already Developed

Table of volumes as [volume_name, x,y,z] with each volume_name containing 8 coordinates of a cube.

Table of vertices to check as [x,y,z]

Functions - Need to determine ConvexHull/Voronoi or existing functions???

Need to compare the vertice table against the volumes

I'll check vertice in a while loop against volume 1, 2, n...

If not in any volume, record vertice row within the vertice table as a DeleteList

DeleteList compare against original List and reogranize vertice table

Other Notes:

Cubes are not oriented along XYZ

Not sure if Convex Hull can generate rectangles or if it "balloons" the rectangles.
