It turns out that using point sprites is not an option for me as I now have a
requirement that the objects must rotate with the world. I could use
AutoTransform with setAutoScaleToScreen(true) and
setAutoRotateMode(NO_ROTATION), but it's still not quite fast enough for my
application. I am holding at around 19 fps, but I'd like to get it to at least
25 fps.
My scene graph contains several thousand MatrixTransforms arranged like this:
Root
| ...
MT ( x 2000)
/ \
MT MT
/ \ / \
MT MT MT MT
\ | | /
AutoTransform
|
Geode
At my default zoom level, only about 32 objects are visible at a time.
Is there anything else I try to improve performance while maintaining the
constant screen size and rotate-with-world properties?
...
Thank you!
Cheers,
Michael
