[Golist] Go & Papervision3D integration

[Moses Gunesch]

Yes,

I am planning on PV integration in a few areas. What you're talking  
about is direct integration with the display system, I'd very much  
like your (and others') help on this since I haven't worked with PV  
enough to know where the problems are. But in general you are totally  
on the right track when you say,

There is a real possibility of some very tight integration here. Go  
tween classes could accept references to renderers and cameras, and  
could automatically update them with animations. It would also be very  
possible to use Go's extensible management architecture to build a  
manager to handle a more complex scene, so that after all animation  
updates are done for that scene, it gets re-rendered just once (vs.  
once per sub-animation which would slow things down).

-

The second area is with Collada or other exported animation – I've  
already made some great progress in that area, working with their team  
to help them design a system that exposes just what is needed for any  
external animation system to interface with and run timeline-style  
animations. They've been really busy but we hope to have something out  
on that within a week or two.

:-)
