示例1: getTruncateTransform

function getTruncateTransform(polyhedron: Polyhedron, result = ''): Transform {
  if (polyhedron.isRegular()) {
    return vector => vector;
  }

  // If we're doing a bevel, we need to do some fidgeting to make sure the created
  // faces are all regular
  const truncateLength = getTruncateLength(polyhedron);
  const oldSideLength = polyhedron.edgeLength();

  const multiplier = getRectifiedMultiplier(result);
  const newSideLength = oldSideLength * multiplier;
  const faceResizeScale = newSideLength / truncateLength;

  const reference = Polyhedron.get(result);
  const normalizedResizeAmount =
    reference.faceWithNumSides(6).distanceToCenter() / reference.edgeLength() -
    polyhedron.smallestFace().distanceToCenter() / newSideLength;

  return (vector, vertex) => {
    const smallFace = find(vertex.adjacentFaces(), {
      numSides: 6,
    });
    const normal = smallFace.withPolyhedron(polyhedron).normal();
    const transform = withOrigin(smallFace.centroid(), v =>
      v
        .scale(faceResizeScale)
        .add(normal.scale(normalizedResizeAmount * newSideLength)),
