I must be really bad at keyword searching because I've been searching with no luck ... also I have nothing significant to give back to the community code-wise so feel a bit guilty about asking more questions ... I'll donate $$ to the cause eventually or any other way to give back let me know.
I have a sphere with a bitmapfile material applied to it. I want to "project"/"draw"/"overlay" a smaller bitmap file onto the sphere bitmap. i.e. create the earth with bitmap file and sphere primitive ... now show a small airplane bitmap "flying" along the surface of the earth with position updated each frame render. I've looked at the Away3dTextureProjection demo and it's uber cool but I take a huge perf hit (I'm working with alot of objects). Using shaders to do "overlays" and I get a huge perf hit (working with alot of different objects). It seems like I should be able to "grab" the bitmap image on the sphere, place the smaller airplane on some point on the sphere bitmap and put them together back on sphere each enter frame ... ???? If this is possible how do I get access to the bitmap and plop the airplane onto it? Cheers in advance. Joseph
