Hi Dean, 

I'm working on a 3d graph based on a data feed from another site. 
The data used for the graph is changing several times per second so I have to redraw it very often. 
The problem is that when I redraw, the camera is reset to the original position. 

Is there any way to redraw the graph while keeping the camera in the position it was? 

Thanks.

pre3d should not be doing anything that resets the camera, are you
explicitly calling .reset(), or setting a new transform? Or perhaps
you are calling autoCamera again (which will reset everything?).

You could take a look at some of the examples, I think they more or
less do what you'd want.

Dean, thanks for the quick response. 
I got it working by removing the autoCamera() and setting the camera as the one from the previous render. 

However, every time I rotate with the mouse, the graph is reset to the whatever the first value was until I stop rotating. 
Any clues?

Got it working! Problem was setting the previous camera to the new render. I just cleared that line and it was fixed! 
Thanks for the help.
