Abstract
This thesis investigates the integration of spatial motion tracking and pixel mapping for synchronized lighting control between real and virtual spaces, with a focus on applications in virtual production environments. Through a series of experiments conducted in a green screen studio, the research evaluates the workflow, efficiency, and creative outcomes of using tracked versus non-tracked lighting setups. The methodology centers on employing Aputure MC Pro lights, wireless DMX (CRMX) transmission, a Vicon tracking system, and Unreal Engine's pixel mapping and DMX control capabilities. Two principal shot scenarios are examined: one simulating the movement of sunlight using a single tracked light to drive digital updates within Unreal, and another comparing how environment-centered (tracked) and fixed (untracked) lighting approaches affect setup time, and adaptability. The tracked lighting method allows real-world light positions and rotations to directly inform digital lighting, resulting in more authentic shadow movement and interactivity than is possible with static or manually programmed fixtures. In contrast, the non-tracked approach, while requiring less technological infrastructure, proves to be less efficient, more labor-intensive, and less capable of achieving certain dynamic lighting effects. The results highlight the benefits of tracked lighting, including improved workflow speed for complex setups, greater artistic flexibility, and more accurate reproduction of single-source dynamic lighting such as a moving sun. However, the study acknowledges the barriers to broader adoption, notably the requirements for motion capture infrastructure and technical expertise. It also identifies challenges such as calibration, potential data jitter, and the need for seamless linking between physical and virtual systems. The thesis concludes by pointing to future research directions: the exploration of alternative tracking and lighting technologies, development of purpose-built tracked fixtures, the adoption of zone-based lighting control for improved scalability, and integration in educational settings. These findings underscore the promise and practical considerations of spatially synchronized lighting in advancing both the art and efficiency of virtual production.
