CloudCompare forum

I want to convert a colored point cloud surface to a grayscale point cloud then convert this grayscale image to another point cloud that represents this grayscale image eg dithering.

Want to do this for 3D Crystal Laser engraving purposes - the laser only has on/off and creates little bubbles. Is there any sort of algorithm or function in cloudcompare that does this?

The first part should be easy (converting RGB to gray scale). You can for instance use https://www.cloudcompare.org/doc/wiki/i ... alar_Field and extract the 'composite' field and display it with a gray color scale.

But I'm not sure to understand the second part...
