📖 Full Details
This virtual production system revolutionizes filmmaking by enabling real-time compositing of live-action footage with computer-generated environments. Using HTC Vive Tracker mounted directly on a physical camera, the system tracks the camera's position, orientation, and lens parameters in real-time, transmitting this data to Unreal Engine 5 at sub-centimeter accuracy.
The virtual environment renders the correct perspective based on camera movement, creating seamless integration between actors on a green screen stage and dynamic virtual backgrounds. This eliminates the need for post-production compositing and allows directors and cinematographers to see final-quality shots during filming.
Key technical achievements include custom Blueprint development for tracker-to-camera calibration, lens distortion matching algorithms, and a synchronized delay compensation system to ensure pixel-perfect alignment. The system supports multiple camera configurations and includes a real-time color grading pipeline that matches virtual lighting with practical on-set lighting.
This technology has been deployed at Gothenburg Film Studios for short films and commercial productions, demonstrating significant time and cost savings compared to traditional green screen workflows.
