Thanks Lionel and Robert for the quick reply.

I tried what Lionel suggested but in fact the geometry generation is much more slow now.
Anyway, since I suspected that "dirtyDisplayList()" is the cause of the delay, I tried to remove that line but without it I cannot see the new color.
Now, is "dirtyDisplayList()" really required for what I need or is there a different call should I use just to see the triangle with the updated color?
