[JAVA3D] Capturing the Canvas3D Image

[Kasparian, Raffi J.]

I am not having great success with the tried and true image capture
routines. Sometimes images are captured correctly and other times only
partial images are generated. When capturing every frame drawn, performance
is severely degraded and many times the Canvas3D itself only shows partial
or blank images. I tried putting the IO routines in a separate thread to
which I simply pass the postSwap-captured images but performance remains bad
and the captured images are no better. I changed HelloUniverse to capture
every frame to disk and am attaching my two source files. Two buttons "Start
Capturing" and "Stop Capturing"  control the capture process. (Images are
saved to the folder "C:/CaptureHelloUniverse". Please, someone, let me know
if I am doing something wrong or try the program out on your computers to
see if it works better on your systems. The boolean variable useIOThread in
CaptureCanvas3D can be changed and the program recompiled to change from
handling the IO in the same thread as postSwap or in a different thread.

Thanks,


Raffi
