Octahedron challenge
Can you create something like this using Point3D
and Polygon3D
elements? Don’t worry about including the colors; they’re just to emphasize how the polygons fit together.

Sphere contour challenge
Can you create something like this using Sphere3D
, Plane3D
, and IntersectionCircle3D

A hands-on tour of some new 3D elements
These materials are from a short workshop at the 2024 International JSXGraph Conference. You can watch a video of the workshop to learn more about how they were used. They’re available here, in a public Git repository, and (for the templates) on JSFiddle.
