Attribute blur

[Zetha]

I was using "Attribute blur" to soften a geometry. It has 90 degree angles, and it is working fine, soften them.

But... anyone knows how it works? Now I am making random solutions.

 

The information of side FX says:

This node blurs any floating-point attributes, including position, color and texture coordinates.

Blurring point positions effectively smooths the geometry if points lie on a surface.

For each point, it creates an average of the position (or any other attribute) values of the surrounding points, using their proximity as weight in the result, and blends it with its initial value. It repeats the process a certain amount of times equal to the number of iterations.

You can replicate it using point cloud, same process to Anto's explaination. Get close points and output averge position wiht pcfilter, higher max points higher smoothness.
