I wanted to try to write a lib similar to [react-three-fiber](https://github.com/react-spring/react-three-fiber) but for VueJS.
I started from scratch,
Demos : https://troisjs.github.io/trois/

## InstancedMesh
Take a look at [Test3.vue](/src/components/Test3.vue).
### Template
```html
<Renderer ref="renderer" :orbit-ctrl="{ enableDamping: true, dampingFactor: 0.05 }">
<Camera :position="{ z: 100 }"></Camera>
<PhongMaterial id="material" color="#ffffff"></PhongMaterial>
<Scene id="scene1">
<PointLight color="#ffffff" :intensity="0.5" :position="{ y: 50, z: 50 }"></PointLight>
<PointLight color="#ff0000" :intensity="0.5" :position="{ y: -50, z: 50 }"></PointLight>
<InstancedMesh ref="imesh" material="material" :count="1000">
<SphereGeometry :radius="2"></SphereGeometry>
</InstancedMesh>
</Scene>
</Renderer>
```
### 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;
```
## GTLF
Take a look at [TestGLTF.vue](/src/components/TestGLTF.vue).
```html
<GLTFViewer src="test.glb" :camera-position="{ z: 1 }">
<AmbientLight></AmbientLight>
</GLTFViewer>
```
