Image-Based Walkthrough over Internet on Mobile Devices
Real-time rendering of complex 3D scene on mobile devices is a challenging task. The main reason is that mobile devices have limited computational capabilities and are lack of powerful 3D graphics hardware support. In this paper, we propose an Image-Based Rendering (IBR) system for mobile devices to visualize real-world or synthetic scenes in network environment. Our system uses server for computing the required image segments of pre-captured panoramic video, and transmitting them to client. After receiving data, mobile client carries out rendering using simple image warping. The rendering process needs less computational power and is insensitive to the scene’s complexity. A rate-control scheme is designed for efficient use of network bandwidth for handling network congestion. Pre-fetching and cache management are also considered on client and server sides for efficient memory use and reducing transmission request. With this client-server architecture and local rendering scheme, inte...
