5.2.8.5: Using pythreejs to generate and view three-dimensional models

It is possible to use output from pythreejs in Libretexts pages. The examples below are taken from the pythreejs documentation and are licensed under the BSD 3-Clause License.

Primitive 3D shapes can be constructed and viewed as follows. Click and drag to explore the shape.

from pythreejs import BoxGeometry
BoxGeometry(
    width=5,
    height=10,
    depth=15,
    widthSegments=5,
    heightSegments=10,
    depthSegments=15)

More complex shapes can be constructed and viewed as well:
