Duality of Regular Solids
Continue to the duality exampleTwo polyhedra are dual if:
- The faces of one correspond to the vertices of the other, and vice versa.
- Each edge separating adjacent faces in one corresponds to the edge joining the corresponding vertices in the other.
- Tetrahedron is dual to tetrahedron.
- Cube is dual to octahedron.
- Dodecahedron is dual to icosahedron.
- To rotate a dual pair, drag the mouse over it while holding the LEFT button down.
- To bring a dual pair closer to or farther from the camera, hold the mouse WHEEL (MIDDLE button) down and move the mouse up or down. (Due to a fit of sloth, I haven't implemented this for turning the mouse wheel.)
-
To bring the camera closer to or farther from a dual pair,
hold the SHIFT key down and either
- rotate the mouse WHEEL or else
- hold it down and move the mouse up or down.
- To move a dual pair around, drag the mouse over it while holding the RIGHT mouse button down.
-
To roll a dual pair around, drag the mouse over it while
either:
- holding the LEFT button and the SHIFT key down; or
- holding bother LEFT and RIGHT mouse buttons down.
- To zoom the camera, drag the mouse (anywhere) while holding down the LEFT and MIDDLE (WHEEL) mouse buttons.
- To move the camera in a plane relative to an object, drag the mouse on that object while holding down the MIDDLE (WHEEL) and RIGHT mouse buttons.
