pixomondo meets Active Crown, tens of thousands of people compete in the stadium

During the production process of the commercial, Pixomondo used the Vicon motion capture system to drive 3D real-person scanned characters to create character animations, and then operated the instance ratio static mesh crowd simulation system developed by Pixomondo in real-time in Unreal Engine to randomly assign motion capture images to individual crowds in the venue, thereby achieving efficient and realistic simulation of crowd assets. Finally, the virtual crowd assets in Unreal Engine were projected onto the LED screen in real time, and Active Crown was used to perform high-precision position tracking of the camera. Even under high-speed shooting of 200fps, the camera movement data of each frame is ensured to be accurate. In this way, the team can capture the motion of small-scale actors in a limited space, and then passThe algorithm scales to synthesize the natural dynamics of thousands of virtual viewers.

Program advantages

Frame-level precise matching: Active Crown's high-precision tracking allows the movement of the virtual camera to be completely synchronized with the real shooting, effectively avoiding errors during post-production synthesis.Screen misalignment problem.

Efficient production process: Since most of the shots are completed in the virtual environment, the workload of post-production adjustments and repairs is greatly reduced, thus significantly shortening the production cycle.

Controllable cost: no need to organize large-scale group performances, only a small number of actors are needed to coordinate the movementsBy simply capturing, you can generate a realistic stadium effect of 10,000 people.
