| Popis: | Present multi-view display techniques are often based on the use of multi-pass algorithms, one per view usually besides an additional step for image compositing. Generally linearly dependent on the number of views, these approaches introduce a bias by incorrectly considering that depth information is located at the pixel level, while the sub-pixel level would be more suitable to improve the intrinsic quality of the resulting images. In this paper, we introduce a new method for rendering multi-stereo views at interactive frame rates which is innovative on two main aspects: first it is based on an OptiX™ ray-tracing engine, second it uses a single premixed rendering pass operating at sub-pixel level. This approach has been tested on a specific volume rendering algorithm, natively supporting 3D displays. After a detailed description of our method, we present performance results for different use cases on an 8-view autostereoscopic 3D display. Quantitative aspects of the latency as well as resulting perceived image quality are measured for the proposed method and compared with a conventional multi-pass GPU approach. |
