Dynamic shading based on fly through altitude

Good morning everyone.  Disclaimer here, I am new to GM scripting and development, though fairly comfortable with other platforms.  That said, I may be asking something that is ridiculously simple or beyond the unreasonable/impossible. 

As part of flight path reconstruction and fly through, I would like to identify terrain clearance in relation to the current altitude on the flight path,  Stuff that is below by a certain amount, green or unshaded, stuff nearer to the flight path a different color, and terrain above the flight path in something like red.

The problem is that the terrain shading will change point by point in a climb or descent.  I realize this has the potential for huge computational loads.  The question though is, can it be done at all?

    Hello John,

    Can I get a little more info on your workflow?  Are you looking to do this in the application or are you planning on making your own application to do this?

    Hi Aaron.  Thanks for your reply.  My preference is to do this within GM.  I don't (yet) have a developer licence, so at this point scripting is it.

    In essence, I have a 3D flight path (lat, long, abs altitude) and I would like to use that absolute altitude as a determinant for a shader.  Not sure if that helps, just let me know.
