Real-time Novel Rendering Architecture for 3d Display
نویسندگان
چکیده
This paper proposed the novel rendering architecture based on GPU massive multithreading for generating multi-view content to 3D display. With the input of 2D plus depth images, this system can support stereoscopic display as well as auto-stereoscopic one. In order to achieve real-time and high quality depth image based rendering (DIBR), anti-aliasing pixel rendering, unoccupied pixel inpainting and multi-view interlacing are proposed and optimized based on parallel architecture. Meanwhile, the GPU-based resizing is also developed by using GPU CUDA interpolation function. The antialiasing pixel rendering algorithm, considering occluding effect simultaneously, is to solve the depth aliasing and disparity quantization problem by using floating-point based mapping to check occupying proportion. Verification on NVIDIA GeForce GTX280 GPU has demonstrated the real-time high quality performance for the proposed novel rendering architecture. Keywords-component: 3D display, anti-aliasing, depth image based rendering, GPU, CUDA

With the rapid growth of smart device and Internet of things applications, the volume of communication and data in networks have increased. Due to the network lag and massive demands, centralized and traditional cloud computing architecture are not accountable to the high users' demands and not proper for execution of delay-sensitive and real time applications. To resolve these challenges, we p...
متن کاملVideo Flashlights: Real Time Rendering of Multiple Videosfor Immersive Model Visualization
Videos and 3D models have traditionally existed in separate worlds and as distinct representations. Although texture maps for 3D models have been traditionally derived from multiple still images, real-time mapping of live videos as textures on 3D models has not been attempted. This paper presents a system for rendering multiple live videos in real-time over a 3D model as a novel and demonstrati...
