[Papervision3D] camera.orbit() camera.rotationY and displayList

[John Brookes]

Trying to work out why certain things are happening.

I take it scene.displayList() doesn't show any particular order.
Is there a way to get displayList in its Zsorted index or display order?


Why does camera.rotaionY not equal camera.orbit();
Camera.rotationY seems to go 0->90->0

Example here www.shrewballooba.co.uk/pv/example03.html

// Uses Latest AS3 branch (todays)
// * NOTE the order of the colours should spell PARTS or STRAP just made it
easier ;)
