BCNoids//blur

Hi everybody.

is there any way of filtering geometry in any renderer?
we would like to Blur some circles, and then, use a posterizeor a gradient map filter, like in photoshop, to have nice interpolated fake metaballs.
Here is a beautiful example made with Flex.

is it possible to do it without using a shader?
or is there any way of modify slightly a shader already done with this purpose?

Thanks a lot.

We are visualizing the data set we gathered from Bicing, (bike shared system in barcelona) through kml.

We have some few experience of v from node08, and this is the first project we want to develop with v.
we’ll post our already early results as soon as possible.

Don’t think that this is possible, but since most (all?) objects you use have transformation information, you can use that Transform, and create some new objects, scale them, use a a shader, whatever, and than put it BEHIND the original.

For example, U7Angel made his cool Crepuscular Rays patch based on this approach.
