Documentation for setup

[adwaitsharma]

Sorry if I missed it, but can someone help me to find the documentation for setting up the 3D hand-tracking? More specifically, I am interested in joint coordinates.

You can build the 3D hand tracking Android demo by

bazel build -c opt --config=android_arm64 --define 3D=true mediapipe/examples/android/src/java/com/google/mediapipe/apps/handtrackinggpu

The hand landmark graph provides a "hand_landmarks" stream, which contains the coordinates. However, since we don't have desktop demos yet, you probably only can get them on Android and iOS.
