Firstly and easiest imo, would be the modification of JC's virtual camera he used for shooting in The Volume.
Those of you familiar with this piece of kit may not have considered the fact that that although Avatar was made to be 3D the display output of the virtual camera is in 2D.
Surely it would be quite easy to make the real time output from the virtual camera 3D, this would make the camera man and the director's jobs easier in regard to reducing camera shots which cause headache's for people sensitive to 3D movies.

Secondly and much more difficultly, it would be useful if the 3d editing and compositing software could automatically remove digital assets and discrepancies which could cause the 3D effects to look odd. More specifically in redard to procedurally animated effects which get too close to the virtual camera adn loom in the foreground.
Such problems occurred in production during the simulation of insects. Many of the people who worked on the film (I’ve spoken with some of them over on a well known CGI community forum) described instances when entire shots were sabotaged when an insect or particle came so close to the camera that it became the only thing you could make out.
Also in the finished film there were instances when wood sprites were in the foreground and it looked odd in 3D.
Personally I preferred it in 2D, but that’s just me.
