FXtree DOF 2004-06-02 - By Luc-Eric Rousseau
Back
The depth of field effect in the fxtree is
the old 2D Output Shader of the same name.
It's a slow accumulation buffer method, although that
wasn't obvious when it's used an output shader, since
the rest of the render isn't instantaneous. It's still
the same in XSI 4.0, however since there
is an SDK to add plug-in in V4.0, one could
write a fast Z Blur - which isn't exactly the same
algorithm, but it's a good approximation of the
result - to replace it.

I too come from a DF background, and have the same problems with the FXTree.
In particular, the fact that you have to let go of a slider before getting
any feedback, as opposed to getting on-the-fly feedback as in DF.
