The Code
const { manifold } = bitbybit.manifold;
const { occt } = bitbybit;
const s = async () => {
createEnvironment();
const sphereManifold = await bitbybit.manifold.manifold.shapes.sphere({
radius: 1,
circularSegments: 32,
});
const span = bitbybit.vector.span({
step: 0.1,
min: -1,
max: 1,
});
const slicedManifolds = await manifold.booleans.splitByPlaneOnOffsets({
manifold: sphereManifold,
normal: [1, 1, 0.3],
originOffsets: span
});

step: 0.2,
min: 0,
max: 4.2,
});
const translatedManifoldPromises = [];
