[JAVA3D] Updating text on overlay

[David]

I feel like I am very close.   I have my overlay geometry rendering nicely.  Text is crisp, background of chat box is partially transparent.  Ok so a few questions:   1) If I just generate a whole new texture, say twice a second, what happens?  Garbage collection aside, will this end up causing my video card to start swapping textures madly?  Is it smart enough to realize that once the texture is removed from my shape that it is to be "deleted" from the video card?   2) I really don't want to use the byreference flag since it was posted this is not standard, nor dependable that a copy will not be made.    3) If I do the yUp and by reference thing then my texture comes out upside down!  I am using a buffered image and drawing onto it.   4) If I do byreference, but not yUp, will it solve the texture swapping problem, but still allow me to set the ImageComponant over and over, paying the price for the copy, but handling the video card correctly?   Thanks in advance!   Dave Yazel
