### 背景
由于需要在web端做元件渲染，目前的解决方案是基于Threejs的，需要基于glTF文件做解析。
@zhangleio 已经开发了转码工具，需先集成到Paracraft中。
使用流程：用户点击上传，选择源文件，web端调用本地API，Paracraft生成gl文件并返回文件地址。web端提交源文件、gl文件以及其他描述信息到服务器端

Chrome/FF are starting to roll out WebGL2 behind a flag. See some of the changes to GLSL [here](https://github.com/stackgl/glsl-tokenizer/issues/4).
We'll need to figure out a way to handle different…

Let's try to optimize the scene, currently it's a little too janky on devices without a dedicated graphics card
Lets try to:
* Switch all the Geometry to BufferGeometry
* Switch the BoxGeometry…

A lot of 3D engines have 'chunking' systems that forms a single uber shader with lights, normal mapping, etc. Most of them just lead to huge shader source with a crap ton of `#ifdefs` (see ThreeJS).

As for my PC, current WebGLRenderer usages result in quite a visible aliasing, so an explicit FXAA shader should be considered.
There are also other options like SMAA, SSAA, TAA.

Would be nice to have a way for compressed 3D Textures and TextureArray for custom shaders.
Request is done after:

Hi,
I did some surface and line plots recently and found the amount of aliasing rather distracting. Then I discovered SMAA and SSAA postprocessing in three.js and tried to add them to the plots. Af…
