Is it possible to adjust height for any object by adjusting brightness, or even color for height?
Anything black would be flat.Anything white would be the tallest.
I create a grid of a checkerboard.All white squares would be the same height and i could adjust them up or down.
Every black square would remain just flat surface. Now if i added a few 50% gray areas to the grid, those would be half the height of the white or tallest squares, and by adjusting the white squares the gray would also adjust to keep it's 50% height.(unless i lock that shade of gray)
And i could keep adding different shades of gray and have different heights.By adjusting one the others would adjust (unless i lock that shade of gray).
Of course this would work on any shape as the effect is controlled by the shapes brightness.
So i could effectively create a sort of city scape or 3-D graph.
Example - Sorry the drawing example is so crude.
