DYNAMIC STEREOSCOPIC PREVIZ

The pre-production stage in a film workflow is important to save time during production. To be useful in stereoscopic 3-D movie-making, storyboards and previz tools need to be adapted in at least two ways. First, it should be possible to specify the desired depth values with suitable and intu-itive user interfaces. Second, it should be possible to pre-view the stereoscopic movie with a suitable screen size. In this paper, we describe a novel technique for simulating a cinema projection room with arbitrary dimensions in a real-time game engine, while controling the camera interaxial and convergence parameters with a gamepad controller. Our tech-nique has been implemented in the Blender Game Engine and tested during the shooting of a short movie. Qualitative exper-imental results show that our technique overcomes the limita-tions of previous work in stereoscopic previz and can usefully complement traditional storyboards during pre-production of stereoscopic 3-D movies.
