As explained in their website and Wikipedia, the Protocol Buffers (or Protobuf) is "used to serialize structured data". The definition of the data structure is done in a .proto file that can be compiled by protoc and turned into code (.cc/.h, .py, .java...) that can be imported to several languages to manipulate and serialize the data.
My understanding is that the .pb files contain that data in binary and the .pbtxt are an equivalent that contain it in ascii. Is that correct?
If so, why are .pbtxt so readable? I've found some with commentaries (https://github.com/google/mediapipe/blob/master/mediapipe/graphs/hand_tracking/subgraphs/hand_renderer_cpu.pbtxt).
Also, are .pb/.pbtxt enough to interpret the data? Or do you need their .proto?
