A Real-Time Interactive Previsualization Platform for Motion Control System In Virtual Film Making

摘要

Motion control system is an irreplaceable technology for bringing creative ideas into reality in visual effects production. It could implement complex camera movements as well as repeat the same movement several times, but there still exists limitations for its expensiveness and complexity to operate. In on-set shooting, it often takes times of motion planning and shooting test to get desired footage, which is time consuming, low efficiency and high costs. If the shot could be previsualized at virtual environment in advance, it would save shooting time, raise efficiency and reduce the costs. By using this approach, all kinds of design and test work is pre-finished during the Previz stage. The motion data of the camera is able to be converted into formats supported by motion control system thus could be used on-set directly. To meet this requirement, this paper designs a real-time interactive Previz simulation platform which could be applied on motion control system. This system previsualizes footages and perform device testing in virtual environment, and the Previz data could be used directly on real motion control system in on-set shooting.
