help on particle emission on polygon surface colission

[creativation]

pls help i cant find any answers on any forum about my problem...

is there an alternate way i could use shading networks to emit particles from polygons i have seen the tutorial but it uses nurbs and a specific node, "closestPointOnSurface", but is there anotherway for this to work. our scene is about a character coming out from a monitor and the character is modeled from polygons and the intersection of that will emit particle effects and we are using Maya 7.

Pls help if there is another way for this or atleast another technique on how to emit particles from the collision of two polygons. Any help or tutorial would be greatly appreciated Thanks.

create a peice or nurbs geometry that looks like the part of the character the collides with the surface. Create the particle collision based on the nurbs surface, and parent the nurbs surface to the part on the character that collides. Then disable rendering on the nurbs surface, cache the particles and delete the nurbs surface, or make the nurbs surface transparent with no reflections and disable all light links; which ever works best.

Another technique is to use toon intersection outlines

One of the sample pictures shows a lesson that explains how to do it. As the character walks, contact with the ground creates intersection lines that you can emit particles from.
