[Blindmath] Isometric graph paper

[Susan Jolly]

If by 3d graph paper you mean isometric graph paper the previous poster is exactly right.  Representing 3d objects in two dimensions or a plane relies on creating an optical illusion that makes sense to many sighted people.  I suppose a blind person could memorize the rules for doing this but I don't see the point.

If you actually want to graph a function of 2 variables in physical space you would need to build some sort of complex contraption.

There are toys which allow you to create a cube by connecting 12 sticks together.  If the connectors are soft enough you can flatten the cube so a blind person could feel what a 2d projection of a cube is like but I think it would be hard to recognize it as a cube.  

I'll be interested in feedback from TVIs.  I can't think why this is important.

Best wishes,
