buffered-interpolation

This package aims to provide a solution for interpolation of position, rotation, and scale for networked THREE.js objects.

It specifically aims to work well both in situations with continuous and sparse network updates.

For position and scale, uses either linear interpolation (default) or hermite function (which takes into account velocity).

For rotation (quaternions), uses spherical interpolation.

var InterpolationBuffer = require('buffered-interpolation');
let interpolationBuffer = new InterpolationBuffer();

on receipt of networked data:

interpolationBuffer.setPosition(new THREE.Vector3(data.x, data.y, data.z));

in some update/tick method:

object3d.position.copy(interpolationBuffer.getPosition());
