I want to calculate shortest distance from an triangular array (with say 400 points) to a point above in the sky. For example, if I am at a point (100, 100, 1000), and the point in the triangular array directly below is (100, 100, 152), what is the best way to calculate the change in elevation (1000-152)? Intersect from sky point to a point in a triangular shape, but how is the coordinate of point in the sky determined and how to determine the intersection directly below the point? Thanks for your help in advance.
