I have been using the DepthAI API and learning how to build complex pipelines with it. After looking at some examples using the SDK, I am interested to look into the SDK since it seems to make life a lot easier. However, the SDK documentation does not provide enough details on how to use the PipelineManager, NNetManager, etc. In searching around in this forum, I came across a few links such as https://docs.luxonis.com/projects/sdk/en/latest/managers/preview_manager/. But these links all seem to be broken. Can someone please provide a pointer for the detailed documentation for the DepthAI SDK basic classes like FPSHandler, Previews, etc. and the SDK managers such as the PipelineManager, NNetManager, BlobManager, etc.? Thanks!
