At the 3D & Virtual Reality Expo, NAC Image Technology demonstrated a real-time 3D virtual system. This combines a motion capture system, 3D photography system, and the Brainstorm virtual studio system.
"In this motion capture area, you can obtain the position coordinates of all moving objects. So there are markers on all the moving objects. There are markers on the caster, motion actor, stereo camera, virtual camera, and flip chart. So all their positions can be detected, enabling CG to be added to all the moving objects. This enables us to achieve a real-time CG virtual studio, which wasn't possible until now."
With this system, 3D absolute coordinates are obtained in motion capture, so CG and actual objects can be superimposed without contradictions.
In a space with CG alone, you can display the point of view from objects with markers. In other words, all the objects are virtual cameras.
"You could do this with anything; for example, a plastic bottle, or just a box. Attaching markers to objects turns them into virtual cameras. So you can see things from entirely new angles, and have motion as well. You can also use lighting, rather than just a camera. Using illuminated objects enables you to create the effect of roaming spotlights, for example."
