50000 rectangles
If you have not been following along, I described rectangle weight in 50000 Rectangles #2 and pixel weight in 50000 Rectangles #7.
Now we can view the image as a surface in 3D space. The pixel coordinate is x,y, and we use the pixel weight for z, height. We can shine light on the surface and create shadows and reflections.
One could do that. But that is not exactly what I am doing. To be continued…
