See KhronosGroup/glTF#1691 for implementation spec.

比方说这样的材质代码，基本上都是雷同的处理操作给shader传值或者拿到值。那么我想到的一种代码优化是类似这样：

class XXXMaterial extends Material {
   @bindToShader('u_emissive_texture', Texture2D) // 对应shader代码里面是哪个变量
   public emissiveTexture: Texture2D;

   @bindToShader('u_time', Float32) 
   public time: number;
}

"Getting started" and "Learning the Basics" are outdated and contain wrong information. We don't have any boilerplate yet. Would be good to update those sections with valid information. Open to ideas :)

Hi, great component.

Unfortunately trying the demo I get WEBGL_UNSUPPORTED whereas https://webglreport.com/?v=1 or v=2 gives me

Linux x86_64 Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:89.0) Gecko/20100101 Firefox/89.0
WebGL GLSL ES 3.00
GeForce RTX 2080 Ti/PCIe/SSE2

and https://get.webgl.org gives me a rotating cube.

Context

This engine is intended to be used as a drop-in replacement to Three.js’s WebGLRenderer.

Problem

It tends not to work as a drop-in replacement out-of-the-box, because the renderer crashes when:

• Meshes contain a THREE.Geometry instead of a THREE.BufferGeometry.
• It uses materials for which the texture images are not loaded yet.

This might cause people who try to repl

Mouse just doesn't seem to do anything.
No clicks, no scrolling. Built from master at c85671e on M1Max, built with latest brew install neovim --HEAD.
Is there some special config I should be adding/removing, or some hints on what I should look at?

Currently the measurement plane is a rectangle defined by the 2 smaller principal axes. Add options to show a disc/circle. This can use code from the membrane orientation visual.

The print style sheet should hide the IDE and enforce the light theme to save pinter ink, then ensure that the layout looks ok in print preview.

This should be a relatively small amount of work.

It would be really useful if there was an option to draw a background grid with the same lines as the tickmarks in the X/Y axis. The grid should ideally be a bit more dampened than the grid lines, eg by using thinner and/or dashed lines.
