[Papervision3D] DOF help

[Daniel O' Brian]

Hi,

 

I'm new to Papervision so excuse any ignorance of what are seemingly
simple concepts to you all.

 

I'm trying to build a project with a similar depth of field effect to
the Absolut clouds in the submitted visions section at
http://www.absolut.com/iaaw

 

I've seen the impressive Mr d00b DOF demo, but this approach (of
creating a sequence of preblurred materials) will not work in ttis
instance as I understand it as each blurred object needs to contain
interactive material.

 

So, I went down the route of applying blur based on distanceTo(camera)
and have a function triggering on ENTER_FRAME which runs a for loop to
update the blur on each item in the scene.

 

Problem is that this seems to only be taking a value from the last item
accessed in the for loop and changing the materials for all items based
upon this.

 

If I blur one item will this also blur any other item with the same
material or is each instance treated as a separate entity? I have tried
creating one material bper object but this slows things down to a crawl
and the same problem as above still applies.

 

Any ideas? Anyone?

 

Cheers

 

Danny O'Brian
