3D mesh object hit testing

adamh128 · 07-04-2005, 10:52 AM

I am writing a plugin that displays a (large) number of small 3D mesh objects, which I would like to be able to click on to highlight some information.

My 3D maths isn't that good, so I need some help...

I am using the PerformSelectionAction plug method to catch button presses, but how would I determine which (if any) of my mesh objects intersect that point and which is the highest one in the Z order?

Many thanks for any help.

Adam.

Hello,
What are you use to make your 3D mesh to insert it in world wind ?
