I found out the hard way about the decal groups :) So now I have my
"decals" floating above the surface slightly and alpha blending in. Works
fine except when you are about level with the decal, then zbuffering freaks
out. Can't wait to have decal groups really working.
I am not sure about the GeometryByReference. Every polygon, with one
exception, is built with a TriangleStripArray. The one exception are shapes
being loaded with the OBJ loader. Any chance the OBJ loader is building
GeometryByReference non-interleaved array?
Sending you an "example" will be a huge undertaking, as the problem seems to
not rear its ugly head with small pieces of my world. My application is
somewhat complex, currently existing in a 20,000 x 20,000 space. Pieces of
the world are built and destroyed as you move through it, objects are built
and moved as needed.
Would updating of the scene graph from multiple threads cause any
instabilities? I suspect it is causing unneeded blocking in the java3d
kernal, I was thinking about changing my threads to send the switch and
transformation changes to a queue sitting in a behavior, so that the live
scenegraph is only touched from within the behavior. Is there any advantage
(blocking) or stability which I might realize as a result of doing this?
