How to make particles explode outward from shape?

Beginners

Hello,

I’m working with a Kinect, and I have it set up to Trace the Kinect player index. I’d like to have particles consistently exploding outwards all around the traced silhouette, but instead the only options seemingly available to me involve the particles looping around the edge of the silhouette, which makes the particles inconsistent (see the attached gif)

Any thoughts on how I can best achieve an effect of having particles consistently exploding outwards all aroundsilhouette?

You could center the silhouette around 0,0,0.
You could then set the normals to be equals the point position, using the point SOP therefore they would all point outwards.
I recommend random point number sorting using the sort SOP, so it doesn’t look so regular too
