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),
);
}
示例2: getAugmentAlignment
function getAugmentAlignment(polyhedron: Polyhedron, face: Face) {
const boundary = getSingle(Cap.getAll(polyhedron)).boundary();
return isInverse(boundary.normal(), face.normal()) ? 'para' : 'meta';
