I can cover a ball object in particle spheres but this is very processor and memory intensive.
I was wondering if I can use the new voronoi textures in Blender 2.82 to make pseudo spheres around the surface? Obviously it won't achieve the depth effect shown balls image attached.
I'm not sure if I can fake a surface displacement with Dot-product to an emission shader or use displacement in Cycles? I would be keen to try an Eevee normal displacement if its good enough.
Currently I cannot get Voronoi texture to represent moving balls very well.
