All my images are PNG format.  I've gotten to the point where I can draw these images using gl.glDrawPixels().  I generate all the byte[] buffers upon load of the game, however this itself isn't adequate if I want images rotated during the game.  What is the best way to implement this?

1) Use Java2D to apply AffineTransform rotation to image and then produce byte[] for each frame.  Seems like this add a lot of overhead, especially with 60+ fps.

2) Use Textures?  I'm wondering if I convert an image to texture if JOGL can do the rotation for me.

3) Any other ideas?

excellent, thanks!
