Yes.

"Then you said there is a “grid of pixels.” Is it a 2-D grid? Or is it a 3-D grid (that is, a 2-D grid with layers)?"
It is a 2-D grid, not with layers but several types of data. For each pixel there is a color, and also a depth of the closest point that landed in that pixel. The depth corresponds to z position. (There can also be a region for each pixel, which allows holons to have different lighting effects, but that's a more advanced topic.)
