In Shader.js:

import basicFragCode from './basic.frag';
import basicVertCode from './basic.vert';
import geometryFragCode from './geometry.frag';
import pbrFragCode from './pbr.frag';

These dependent shaders should be placed in mateiral.

库现在的大包结果是全局处理方式。或者兼容全局模式方式

Spent couple hours trying to get correct normals.
All was about data management:

//Works like that
 points[0].position.copy(data.vertices.get(0));
 points[1].position.copy(data.vertices.get(1));
 points[2].position.copy(data.vertices.get(2));
//Doesn't work like that
const p0 = data.vertices.get(0);
const p1 = data.vertices.get(1);
const p2 = data.vertices.get(2);
//p0 === p1 === p2
points[0].position.copy(p0);
points[1].position.copy(p1);
points[2].position.copy(p2);

All because get returns reference to same vector object. Please, add warning about that in docs, and, optionally, additional method getCopy which should return vector copy

是否可以支持淘宝小程序？

Hi.

I experienced few problems when tried to use cannon by example and think it (example) should be extended:

1. Cannon and Hilo worlds works in different axes: Cannon uses Z as vertical, Hilo Y. It isn't issue itself since you can just set gravity in any direction, but for some bodies like planes it is problem. All ground bodies has to be rotated:

world.gravity.set(0, GRAVITY, 0); //Hilo's gravity direction
const groundBody = new cannon.Body({
		mass: 0, // mass == 0 makes the body static
		quaternion: new cannon.Quaternion(0, 0, 0).setFromEuler(-Math.PI / 2, 0, 0) //hilo's ground rotation
	});

Also i think it would be better to let cannon work in Z direction as it was, but then we need to swap axes like hilomesh.setPosition(this.body.position.x, this.body.position.z, this.body.position.y); and rotation too.
2. Line geometry = new Hilo3d.BoxGeometry( 2, 2, 2 ); incorrect because BoxGeometry works with object argument, const geometry = new Hilo3d.BoxGeometry({ width: 2, height: 2, depth: 2 });
3. It doesn't clear from example that Hilo's bodies (Boxes) has to be twice bigger than cannon's

const geometry = new Hilo3d.BoxGeometry({ width: 2, height: 2, depth: 2 }); 
const shape = new cannon.Box(new cannon.Vec3(1, 1, 1)); //does it because cannon sets distance *from center*?

I don't sure is it problem exist only for boxes or whole cannon-hilo bind.

Thanks for your time!

Because WebGL resources cannot be shared in different contexts, some global classes need to be modified.

I tried Khronos' new test model TextureEncodingTest.gltf with Hilo3d.
However, it seems to be different from the expected result.
