One particle per polygon

[ryansimrell]

I am attempting to generate geometry from Cinema 4D to be used as an emitter with a particle system In touchdesigner.

So far I have been cloning polygons with 3 vertices to the surface of my objects in cinema. Then importing an obj of those particles into touch to use as a “point cloud.”

Problem is when I do this I am getting 3 points per poly where I would rather just one in the middle of my polygon. Anyone have a better solution for something like this?

See this topic for a solution

Particle origin

Sorry for this hopefully dumb and basic question, but how do I get particles to emit from center of a primitive face rather than from the verticies?

That was exactly what I was looking for. Was able to just use the facet sop to consolidate the extra points thank you!

I also answered in the other thread, proposing to use add Sop to create discrete point and point Sop to create normal (particules are propulsed in normal direction and force)

You can also use subdivide Sop to create a point at the center of each face and delete using bouding sphere to only keep the center points You can also use add Sop to create individual points and point Sop to create normal for each point Here is a quick test with the two propositions centerPart.toe (6.5 KB)
