Ah yes, that's prompted me about something I would really like to do: Some texture capability that allows the use of VolatileImage or something similar to that for efficient video texture handling. My understanding of the system at the moment is that even if you have hardware MPEG support, the way J3D is structured is that the frame must come off the video card and then then get written back to it again (texture byRef stuff). That's really inefficient and I would love to have some way of just pointing j3D at a chunk of video card memory space and say "here's a texture, just render it every frame, whatever the contents are". In doing this, it would remove the need for control over individual video frames from needing to come back into Javaland unless the programmer really wanted it. That way, programmers could do other funky stuff with pixelshaders doing stuff outside the J3D space but still have it rendering as needed. > IMHO scenegrpah rendering is perfect for 'little' web-applications, > because it shortens the developing time.

If you design your code properly, that is a non-issue. Have a look at how the particle code and ROAM stuff is working. If I could, I would show you how Xj3D will work, but that's a month or two away yet (code hasn't been written but the design is floating around on a pile of scrap paper here :). These are a heck of a lot more complex than a simple game engine and still we don't need to go to immediate mode. I think that the immediate mode requeusts are just trying to justify the lack of vision on the part of game programmers to change development mindsets.
