    Interface OBJ_Prism

    Prism shape options object that extends OBJ_Generic3All and OBJ_FigurePrimitive

    A prism base is defined in the XY plane, and it's length extends into +z. Use transform to orient it in any other way.

    Triangles will be created for the ends if the base is convex. If the base is not convex, use baseTriangles to define the triangles.

    To test examples, append them to the boilerplate

    // Create a rectangular prism
    figure.add(
      {
        make: 'prism',
        base: [[0, 0], [0.5, 0], [0.5, 0.2], [0, 0.2]],
        color: [1, 0, 0, 1],
      },
    );

    // Create a hexagonal prism along the x axis with lines
    figure.add(
      {
        make: 'prism',
        base: Fig.polygon({ radius: 0.1, sides: 6 }),
        color: [1, 0, 0, 1],
        transform: ['r', Math.PI / 2, 0, 1, 0],
        lines: true,
      },
    );

    // Create a bow tie prism defining the base triangles
    figure.add(
      {
        make: 'prism',
        base: [[0, 0], [0.25, 0.1], [0.5, 0], [0.5, 0.3], [0.25, 0.2], [0, 0.3]],
        baseTriangles: [
          [0, 0], [0.25, 0.1], [0.25, 0.2],
          [0, 0], [0.25, 0.2], [0, 0.3],
          [0.25, 0.1], [0.5, 0], [0.5, 0.3],
          [0.25, 0.1], [0.5, 0.3], [0.25, 0.2],
        ],
        color: [1, 0, 0, 1],
        transform: ['r', Math.PI / 2, 0, 1, 0],
      },
    );
