@ -17,54 +17,37 @@ I started from scratch... I don't know if I will have time to maintain this, but
I first made a simple *Proof of Concept*, take a look at [Test1.vue](/src/components/Test1.vue) :
```html
<Renderer>
<PerspectiveCamera :position="{ z: 100 }"></PerspectiveCamera>
<PhongMaterial id="material1" color="#ff0000"></PhongMaterial>
<LambertMaterial id="material2" color="#0000ff"></LambertMaterial>
<Renderer ref="renderer">
<Camera :position="{ z: 100 }"></Camera>
<LambertMaterial id="material"></LambertMaterial>
<Scene>
<PointLight :position="{ y: 50, z: 50 }"></PointLight>
<Box ref="box" :size="10" material="material1"></Box>
<Sphere ref="sphere" :radius="10" :position="{ x: 50 }" material="material2"></Sphere>
<PointLight :position="{ x: 0, y: 50, z: 50 }"></PointLight>
<Box ref="box" :size="10" :rotation="{ y: Math.PI / 4, z: Math.PI / 4 }" material="material"></Box>
</Scene>
</Renderer>
```
## InstancedMesh

### Template
```html
<Renderer ref="renderer" :orbit-ctrl="{ enableDamping: true, dampingFactor: 0.05 }">

<StandardMaterial id="material" :transparent="true" :opacity="0.9" :metalness="0.8" :roughness="0.5"></StandardMaterial>
<Scene id="scene1" background="#000000">
<AmbientLight color="#808080"></AmbientLight>
<PointLight ref="light" color="#ff6000"></PointLight>

### Script : init instanceMatrix
```js
const { randFloat: rnd, randFloatSpread: rndFS } = MathUtils;
const imesh = this.$refs.imesh.mesh;
const dummy = new Object3D();
for (let i = 0; i < 1000; i++) {
dummy.position.set(rndFS(100), rndFS(100), rndFS(100));
const scale = rnd(0.2, 1);
dummy.scale.set(scale, scale, scale);
dummy.updateMatrix();
imesh.setMatrixAt(i, dummy.matrix);
}
imesh.instanceMatrix.needsUpdate = true;
```
