This page is about a feature that is supported only in GeoGebra 5.0. |
- Octahedron[ <Point>, <Point>, <Direction> ]
- Creates an octahedron having the segment between the two points 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 the segment, or
- a polygon, a plane parallel to the segment.
- The created octahedron will have:
- a face with the segment as an edge in a plane orthogonal to the given vector/segment/line/ray, or
- a face with the segment as an edge in a plane parallel to the polygon/plane.
- Octahedron[ <Point>, <Point>]
- Creates an octahedron having the segment between the two points as an edge, and a face contained in a plane parallel to xOy plane.
- Note: This syntax is a shortcut for Octahedron[ <Point>, <Point>, xOyPlane], which requires that the segment between the two points is parallel to xOy plane.
Note: See also Cube, Tetrahedron, Icosahedron, Dodecahedron commands.
