Processing

TrackOSC receiver examples for Processing

Two sketches for Processing 4, both needing only the free oscP5 library.

Sketch	What it does
TrackOSCReceiver	Parses all fifteen TrackOSC messages and draws them in 2D: body skeletons (2D, and the pixel projections of 3D), hand skeletons, face landmarks, boxes and jawline contours, text/animal boxes, animal skeletons, human boxes, barcode quads – with the same coordinate guides as the native macOS receiver. The reference for every other example in this folder.
TrackOSCReceiver3D	Draws /poses3d/arr in real 3D (P3D): skeletons in metres over a floor grid, with the camera marked at the origin. Drag to orbit, scroll to zoom, R to reset.

Setup

1. Install oscP5: Sketch → Import Library… → Manage Libraries…, search "oscP5" (by Andreas Schlegel), Install.
2. Open either sketch and run it. Both listen on UDP port 9527 (the VisionOSC default). Only one program can listen on a port at a time, so quit the native TrackOSC Receiver first.
3. Point a TrackOSC sender at this machine's IP, port 9527 – or test without any camera from the repository root:

cd PoseioscShared && swift run poseiosc-testsend 127.0.0.1 9527

(No Xcode? Examples/Python/trackosc_testsend.py sends the same synthetic scene from Python.)

Adapting the sketches

• Wire coordinates are pixels in the sent frame, origin top-left, never mirrored; the frame size (720×1280 portrait, 1280×720 landscape) is in every message header. Both sketches aspect-fit that frame into the window.
• Joint orders, edge lists and colours are in Examples/SKELETONS.md; the sketches carry a copy.
• A keypoint with confidence 0 is missing – skip it (the sketches already do).
• The full wire format is documented in the root README.
