I've been blind since birth. When it comes to 2d things such as linear and quadratic graphs, shapes such as triangles, circles, squares, etc, I had no issues when the material was provided using braille graphics. I can't comprehend representing a 3d object in two dimensions. When I was in college I switched from Computer Science to Telecommunications the second time I failed calc ii. I just couldn't comprehend rotating a shape around the access of a graph to get a 3d shape. This may be something solvable by 3d printing, but that was not easily available when I was in college.

Do you find the concept of perspective to be totally obscure ?
