Hello Dan,
The main problem with calling setColorArray to update the vertex colors is
that it visibly slows the framerate. Is there any way around completely
resetting the color array on the geometry every frame (update)?
Calling setColorArray() calls dirtyDisplayList(), which is what is
actually needed in order for the display lists to be recompiled and
ready to use with your changes.
If you are updating the color array (or indeed any array in the
Geometry) often, then you should just disable display lists by calling
setUseDisplayLists(false). Also you can experiment with
setUseVertexBufferObjects(true), for some uses vertex buffer objects are
faster than plain vertex buffers but in some cases they are slower.
Display lists are for static geometry. If your geometry is changed
often, the overhead of compiling the display list will severely affect
frame rate as you have seen.
Hope this helps,
J-S
