three a memory block managed on the GPU memory when rendering the model, the memory release after clearing the vertex buffer has a delay, how to use the gl.deleteBuffer (data.buffer) to quickly release memory, can provide a solution, this involves the underlying webgl related knowledge, Hope to get more help thank you.
The is not direct access to the deleteBuffer() WebGL command via three.js. You have to use the dispose() methods on your geometry object so WebGL buffers are deleted.
Since the pad configuration for development is low, there is always a delay in releasing memory, except for dispose, adding new methods to speed up the release of memory buffers, thank you
