I'm trying to get the same result with the "surface" colors in these two pictures:
The cube isn't shiny and nice like the picture with the "balls" at each corner.
The scenes lights everything is exactly the same.
The surfaces are very different the cube with the "balls" are all round, and the other one is square.
Is it simply because the surfaces?
It's some of the impossible illusions, I also got the impossible triangle done in SolidWorks.
