Application of Positioning Systems in XR / Virtual Production / Knowledge sharing
At the beginning of the 21st century, with the rapid advancement of real-time computer rendering technology, on-site real-time interactive previsualisation techniques in front of green screens emerged. During actual shooting, live-action elements captured in front of the green screen are composited with virtual elements in real time on set. However, limited by rendering quality and keying performance, the real-time output on site generally serves only as a shooting reference rather than final footage. High-quality final images still rely on post-production compositing.
