Fragment shaders can be used for such an effect. Also, the 'soften' effect can be done by rendering the geometry several times and offsetting the coordinates slightly. If you have lots of geometry to render another option involves using pix_snap2tex after everything is drawn then applying that texture to several offset rectangles.

hello.

i havent used gem much before, sorry for asking this but i cant find any answers in documentation. i've got some geos being rendered to the screen, and i want to apply a convolution to the entire result.. can i use pix_convolve for this in some way, or can it only be used for image files and textures etc?

and is there a better or cheaper way to do this than use convolution? i just want to blur everything (a soften effect not a motion blur).

thanks. pete.
