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.

Inspired by: godot-snapshot-interpolation-demo

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());
