[osg-users] "LOS" materail query

[Mike Greene]

Hi,

I am wanting to do a dust cloud when an entity (helicopter) lands on a terrain. Ideally, would like the color of the dust cloud to be similar to the material/texture that the entity is on. Is there a way to do a "material/texture color" query based on an entity position, kind of like an LOS intersector test?
Thank you!

Cheers,
Mike
