[JNI] Need fast way to access native array

[bill@xxxxxxxxxxxxx (Bill Tschumy)]

I am working on some Java code that needs to gain quick access to a 
native C array.  The native code is generating the array which 
represents an animated image.  The Java code needs to access this 
code to display it on screen.

I have tried using the JNI call SetIntArrayArrayRegion(...) to copy 
the bits to a Java int array, but this is painfully slow.  The image 
is a full screen display and the copying it takes around 1 to 2 
seconds.  I ideally need to display around 5-10 fps.

I know I've seen various Java based 3-D animation packages that use 
native code for their rendering.   They seem to be getting much 
better throughput.  Is there some other API call I should be using?

Thanks for any help you can give.

Bill
