Abstract

We propose a VR content platform for multi-projection displays. Our platform has in common features with frame synchronization methods without any special hardware and real-time image adjustment mechanism with graphics processing units.We realized the image adjustment mechanisms as image effects. The image effects used multipass rendering, multitexturing, and programmable shaders. Therefore we can easily extend adjustment algorithms, and use multiple effects, and implemented several image filters.In above features, we can reduce workflow to create content for multi-projection display. Because we can efficiently operate post-productions for content for multi-projection display. We used our system to create high-resolution movie contents for seamless multi-projection display.
