Point Clouds

I am trying to find a good way to render a point cloud with Panda3d.

I need to be able to render millions of single pixel sized points, each having a 3d position.

Any ideas?

Maybe you can tap into the particle system? I believe the “point” type’s size is set in pixels. Millions though, you might need something special.

If you want to animate milions of pixels, you can do it by gpu with shaders. But it looks like a relatively complex task. Search for gpu particles system.
