Greg,
Thank you for considering my request. Drawing B is more what I had in mind. That particular gradient would (on my CNC carving machine) create a maze wall that would be high in the center, and slope toward the maze floor on either side.
A would Be a straight vertical drop from the top, and a slope toward the bottom a bit like a saw tooth. Think of it in terms of laying the image you provided flat, tuning it to view from the right side, then A would go up at an angle toward the right,
B would go up, and then back down. The particular shading used defines how the slope would look. the faster the change in grey, the
Okay,
I think I am getting a better idea. It seems like you are not looking for a 3D project of the maze upon a 2D plane like the first image. I think what you might be asking for is a top-down view of the maze, and each "pixel" if you will is ultimately a mapped height at that point.
From your description above, you seem to want the walls to be softer. Rather than the 2 levels your CNC machine would map today given the White Floor and Black Wall, this would cause a sharp angle for the wall (ultimately 90 degrees) around the maze. Image B from above seems to indicate to me that you are looking for more of a channel (sloped walls, maybe more to match say a marble rather than a cube).
Below is a mock-up of what might work for your CNC machine. Although, the black and white might be inverted and the walls might be more gentle like "B" image above.
Is this closer to what you are looking for? So the color (degree of blackness if you will) maps to the depth of the cut into the block of wood or whatever material you are cutting?
