This question is related to my previous thread at: https://forums.developer.apple.com/thread/62727
I was looking for ways update SCNGeometry's source and elements fast, but it seems there is no easy way to this.
To get around this, I am looking into using Metal API for rendering tracing path.
With SCNSceneRendererDelegate method, I was able to access most of the things needed for rendering, except CAMetalDrawable.
Every resources I could find required CAMetalDrawable to render which is nowhere to find.
Could anyone direct me where to look regarding this?
A sample project that renders with Metal API in SceneKit context would vastly help.
Thanks.
