R- xy scatter plot in 3d using density

Question

I want to visualize an x-y scatter in 3d, using the density/overlaps as z values. I guess this would be like using alpha as a z-axis - more overlap = higher z. Suggestions? Perhaps using cloud() in lattice library?

Answer 1

I use rgl for 3D visualization. You can rotate the image in rgl window using your mouse. Wheel zooms in/out.

example(plot3d)
rgl.bg(color = "black") # Space, the final Frontier.
