JOGL question...

Hey guys, I've been trolling here for quite some time - I've gotten a lot of help here so I'd like to start off by saying thanks to all of you.  I'm developing a visualization tool for work and I've settled on using JOGL.  I've actually gotten most of it done but I've not been able to answer a question I've had since the beginning - is there a way to only redraw certain objects?

My project consists of about 90% static objects that, once rendered, really don't need to be redrawn ever again.  But, I also have a few objects that are animated.  I'd like to be able to draw the static objects once, then, as needed, animate the mobile objects.  Is this possible?

Thanks.

try FBO's maybe ..

U could draw the static objects once with Color+ZBuffer information to a FBO. To integrate the animated objects u could simply clone the Color+ZBuffer from the static objects to another FBO and draw ur animated Objects to that FBO. This would reduce the redraw of the static objects to a simple and fast copy/clone operation.

sounds good, i'll give this a try.

Thanks again.
