Re: How Would You Visualize DOF in GL?

[Eric Lampi <ericlampi(at)yahoo.com>]

I think it's pretty funny that in a $50 game you can get real-time DOF with on a $300 video card, but in XSI you have to jump through hoops and deal with long processing times using a $1500 professional video card.

Something is wrong with that concept.

Is this similar to how X-dof used to operate from within XSI prior to v6?

Ok, I have no idea if this is uesful info or not.

I remember a button in lightwave that made a previz of dof in the viewport by slightly offsetting the camera randomly, say 20 times but still pointing at a target (focus point) and then blending the images.

Interesting subject

heya,

So this keeps coming up during pre-vis.   How can a Pre-vis artist pre-vis
DOF in the viewport/GL Capture??

I am curious if this has really been discussed on the XSI side?

I've seen using the depth fog to attempt to do it.. but I feel it's just not
the right solution.

My thought would be ideally to have a way to have GL DOF..   sure it might
looks rough.. but it's for Pre-Vis purposes.  I mean Flash can do it. Games
can do it.. seems like those approaches might have a way to applying to our
GL viewports?

Just curious if this has been done very well?  Or if there are any thoughts
on this...

thanks,
