Here are some source code about marching cubes on Github.(Have tested in Unity2018 and Unity2019)
It includes two version(CPU and GPU) ,which is the foundation of my Test417(https://twitter.com/i/status/1220778085798137856) and Test440(https://twitter.com/i/status/1169084756908105729). Any ideas to optimize the GPU version is really appreciate.
