These show the surface from different viewpoints. Note that Boy's Surface has a three-fold axis of symmetry.
None of the self-intersection is visible.
Rotating the previous picture by 180 degrees makes the triple point and part of the double point curve visible.
Rotating the previous picture by 90 degrees shows another part of the double point curve.
A small portion of the double point curve is visible.
These show the surface colored according to z-coordinate. In the second and fourth pictures the surface has been sliced open.
This view is identical to that shown in the first picture.
The triple point and parts of the double point curve are visible after a "window" has been cut out of the surface.
This view is identical to that shown in the second picture.
Three windows have been removed to show some of the interior structure.
