示例1: doAugment

// Augment the following
function doAugment(
  polyhedron: Polyhedron,
  base: Face,
  augmentType: string,
  gyrate?: string,
) {
  const numSides = base.numSides;
  const augmentee = getAugmentee(augmentType, numSides);
  const underside = augmentee.faceWithNumSides(base.numSides);

  // Determine the orientations of the underside and the base
  const undersideRadius = underside.vertices[0].vec
    .sub(underside.centroid())
    .getNormalized();

  const baseIsAligned = isAligned(
    polyhedron,
    base,
    underside,
    isFastigium(augmentType, numSides) ? 'gyro' : gyrate,
    augmentType,
  );
  const offset = baseIsAligned ? 0 : 1;
  const baseRadius = base.vertices[offset].vec
    .sub(base.centroid())
    .getNormalized();

  // https://math.stackexchange.com/questions/624348/finding-rotation-axis-and-angle-to-align-two-oriented-vectors
  // Determine the transformation that rotates the underside orientation to the base orientation
  // TODO we probably want this as some sort of generic method
  const transformMatrix = getOrthonormalTransform(
    undersideRadius,
    underside.normal().getInverted(),
    baseRadius,
    base.normal(),
  );
  const transform = withOrigin(base.centroid(), u =>
    transformMatrix.applyTo(u),
  );

  // Scale and position the augmentee so that it lines up with the base
  const alignedVertices = augmentee.vertices.map(v => {
    return v.vec
      .sub(underside.centroid())
      .scale(base.sideLength() / augmentee.edgeLength())
      .add(base.centroid());
  });

  // Rotate the vertices so that they align with the base
  const rotatedVertices = alignedVertices.map(v => transform(v));

  const newAugmentee = augmentee.withChanges(solid =>
    solid.withVertices(rotatedVertices).withoutFaces([underside]),
  );
  return polyhedron.withChanges(solid =>
    solid.withoutFaces([base]).addPolyhedron(newAugmentee),
  );
}
