Hi guys (and girls)

is there any way to query the screen or raster position of particles (or anything for that matter) at the time of rendering just like how renderman has screen space and NDC etc.

sorry if this has already been asked,

thanks

Phil

samplerInfo node has pixelCenterX pixelCenterY attrs.This can be usefull.
To normalise into [0-1] range divide it by rendering resolution. (ie: pixelCenterX / 720.0 pixelCenterY / 576.0)
