    buffered-interpolation-babylon

    This is a port of Mozilla's buffered-interpolation to BabylonJS

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

    Usage

    import {
      InterpolationBuffer,
      BufferState,
      BufferMode
    } from "buffered-interpolation-babylon";
    
    const buffer = new InterpolationBuffer(BufferMode.MODE_LERP, 0.1);
    

    on receipt of networked data:

    buffer.appendBuffer(position, velocity, orientation, scale)
    

    in an onBeforeRender observable:

    buffer.update(scene.deltaTime)
    if (buffer.state === BufferState.PLAYING) {
      mesh.setEnabled(true);
      mesh.position.copyFrom(buffer.position);
      mesh.rotationQuaternion.copyFrom(buffer.quaternion);
      mesh.scaling.copyFrom(buffer.scale);
    }
    

    Install

    npm i buffered-interpolation-babylon
