## Introduction

rayTracer is a lightweight ray tracer render engine base on canvas 2d api.

## Feature

Include `light` `object3d` `camera` `scene` `renderer` `reflect` and so on.

rayTracer`s api is very like threejs, you can ease to code your stage by following:

```javascript

const renderer = new JC.Renderer({

  canvas: document.querySelector('#canvas_screen'),

});

const scene = new JC.Scene();

const camera = new JC.Camera(new JC.Vector3(0, 5, 15), 90, new JC.Vector3(0, 0, -1), new JC.Vector3(0, 1, 0));

const plane = new JC.Plane(new JC.Vector3(0, 1, 0), 0);

plane.material = new JC.CheckerMaterial(0.1, 0.5);

scene.adds(plane);

renderer.render(scene, camera);

```
