Hi,

Great work on the Flash 10 branch guys.

I noticed you guys use the root perspective projection to compute the
camera projection. So changing zoom/focus will change the field of
view of the root as well. So if I have display objects outside Away3D
the field of view will affect those as well.

I've been investigating how the matrix used by
flash.geom.Utils3D.projectVectors() works, and it's pretty different
from your usual OpenGL/DirectX projection matrix. I was able to figure
how it works, and how to create projection matrices without relying on
PerspectiveProjection, including off center projections. If you are
interested I posted some code here:

Maybe you already know all of this, but if it can be useful feel free
to use it!

Thanks again,

Stephan Florquin
