This page is about a feature that is supported only in GeoGebra 5.0. |
- Octahedron[ <Point A>, <Point B>, <Direction> ]
- Creates an octahedron having segment AB as an edge.
- The other vertices are univocally determined by the given direction, that needs to be:
- a vector, a segment, a line, a ray orthogonal to AB, or
- a polygon, a plane parallel to AB.
- The created octahedron will have:
- a face with edge AB in a plane orthogonal to the given vector/segment/line/ray, or
- a face with edge AB in a plane parallel to the polygon/plane.
- Octahedron[ <Point A>, <Point B>]
- Creates an octahedron having segment AB as an edge, and first face contained in xOy plane.
Note: See also Cube, Tetrahedron, Icosahedron, Dodecahedron commands.
