Directly obtain the point cloud processed by VertexShader，Does babylonjs have this function？just like OpenGL TransformFeedback
Pinging @sebavan for this
Yup we do support them at the engine level and it is actually in use for our gpu particle system 
Are there any TransformFeedback examples?
You could look into our code how we use it in our particle code Babylon.js/webgl2ParticleSystem.ts at 383f2b61e544293eb712362eda66477e30243251 · BabylonJS/Babylon.js · GitHub
