Constructor

.new Parametric(paramsopt)

Parametric generates a geometry representing a Parametric surface

It is usually used to develop different kinds of highfields or visualize a math function.

Source:
Parameters:
Name Type Attributes Description
params Object <optional>

The params.
Example

Example creating an heightfield-like geometry. `u` and `v` are like `x` and `y` in shape, but their values are always from `0` to `1`. We use them in `THREE.Vector3` like `x` and `z` and `Math.random() * 5` for `y`.

const createParametric = (u, v) => {
  return new THREE.Vector3(u * 30, Math.random() * 5, v * 30);
}

new Parametric({
  geometry: {
    func: createParametric
  },

  material: new THREE.MeshLambertMaterial({
    color: 0xffffff,
    side: THREE.DoubleSide
  }),

  position: [0, 100, -100]
}).addTo(app);
