Hi all! Best thing to do would be bounding boxes. It's fast to calculate and relative accurate. You can calculate bounding box for each object one time and use every time! On Friday 02 June 2006 01:44, Mick - wrote: I'm trying to create a type of collision avoidance capability, and would

I'm trying to create a type of collision avoidance capability, and would need AGL data from in front of the aircraft. Could someone suggest where (in the code) I could get projected elevation information, for example, AGL data 10 meters in front. My understanding is that AGL is taken from the
