is there a way to change the point style of the points in a point cloud from a square to a sphere?

1. A concise explanation of the problem you’re experiencing.

this is not a problem per se…I am just trying to see if the style of the points in a point cloud can be changed from the existing square looking point to a sphere or a circle?

2. A minimal code example. If you’ve found a bug, this helps us reproduce and repair it.

I am looking at the sandcastle example at:

and

The points in the point cloud in both the sandcastle look square. Is there a way to render a point with my own point style (in this case as a sphere)?

3. Context. Why do you need to do this? We might know a better way to accomplish your goal.

Customer is requesting the points in the point cloud to be spherical instead of a square tile kind of point.

4. The Cesium version you’re using, your operating system and browser.

I believe point clouds are rendered as squares just because that’s how WebGL implements the “point” primitive. This is where it’s specified:

I don’t think there’s a straightforward way to change it without losing some performance. Although this article seems to suggest a potential method: https://charto.net/blog/drawing-points-properly-in-webgl/
