Sprinkle with Cd / N attribute?

General TouchDesigner Discussion

I have a textured model that I want to convert to a „colored“ point-cloud.

I can use TOP.sample() to get the texture into the Cd attribute, but after the sprinkle SOP (in surface mode) all color and uv data is lost.

Also wondering how to get approximate normals onto the sprinkled points

Any ideas ?

Still haven’t figured this one out. Is there maybe a way (for each point) to transfer attributes from the closest point in another SOP.

Builds 2022.30390 and later will now have a ‘Surface Attributes’ option.
This will handle normals, texture,Cd etc when sprinkling on surfaces.
It is not currently supported on the volume operations.

Is your setup volumetric? Not immediately clear how to interpolate interior points in that case, especially for bounding boxes.
For surface points, its based on the polygon’s vertices.

Sounds great Rob! Looking forward to test this feature

I’m not using a volumetric setup right now.
