[homuler]

To build Google.Protobuf.dll, dotnet command is required (cf. https://github.com/homuler/MediapipeUnityPlugin#protocol-buffer).
Please install .NET Core SDK(3.x) and .NET Core runtime 2.1.

[ashishkrshrivastava]

@homuler I have already installed using

sudo snap install dotnet-sdk --classic
sudo snap install dotnet-runtime-31

[homuler]

Please make sure that you can run dotnet --version.

Mediapipe examples are already working on my system

[homuler]

Please copy and paste the log when you run make.

[ashrvstv]

Thankyou so much @homuler . it worked
on make install
command

~/MediapipeUnityPlugin$ make install

output on terminal

@homuler Readme doesnot contain instructions to use this plugin inside unity. My objective is to use pose landmarks and render a 3D model over a landmark. Can you please guide me how can i get pose landmarks using this plugin inside unity?

[homuler]

As to pose tracking, I'm developing now (and not finished yet), but the HandTracking example may be used as a reference.

1. Define output_stream you use in the graph config file
2. Initialize the graph
3. Prepare an OutputStreamPoller and the corresponding Packet.
4. Push an image to the graph.
5. Wait and fetch the result.

Overall, I think that the sample code is very similar to the official one.

[homuler]

In 269a081, I added sample code to use pose landmarks.
