🧊 Hand-Controlled 3D Interface

Mediapipe works on Python 3.11 or before, not 3.12!!

This project uses Python, OpenCV, and MediaPipe to read hand gestures from a webcam and control a 3D cube rendered with PyOpenGL. Inspired by the Tony Stark meme, the user can rotate, zoom, and orbit the camera around a 3D object using just hand movement.

🖐️ Hand Gestures (via MediaPipe)

You can map gestures like:

• Pinch (thumb + index) right hand: for zoom
• Point (index and thumn) left hand: for rotation

Currently, OpenCV and MediaPipe identify hands using .multi_handedness, which you can parse to differentiate gestures from left/right hand.
