<p>Real-time global illumination that scales from low to high-end hardware is important for interactive applications so they can reach wider audiences. To do this, the real-time lighting algorithm used needs to have varying performance characteristics.  Sparse Radiance Probes (SRP) is a recent real-time global illumination algorithm that runs in under 5 ms per frame on a high-end Nvidia Titan X GPU. Its low per-frame timings suggest it could scale to low-end devices, but no prior work provides complete implementation details and evaluates its performance across devices with varying performance characteristics to prove this. Therefore, this thesis aims to fill this gap and determine if SRP is scalable across low to high-end devices. SRP is implemented with adjustable scaling parameters, and its performance is compared across three test devices. A low-end iPhone 7, a mid-range AMD Radeon 560 graphics card, and a high-end AMD RX Vega 56 graphics card. The implementation in this thesis ran above 60 FPS for simple scenes on the iPhone 7, and with a reasonable reduction in quality, it ran just above 30 FPS on more complex scenes like Crytek Sponza. These results show that SRP can scale to low-end devices. While the implementation in this thesis runs in real time, there are implementation optimisations that would make SRP run even faster across all the test devices without reducing quality.</p>

With the rapid development of smart-phone applications, how to make the ordering process via smart-phones more convenient and intelligent has become a hotspot. This paper puts forward a method of restaurant dish recommendation relying on position information and association rules. In addition, this paper has designed and developed a restaurant recommendation system based on mobile phone. The system would fetch the real-time location information via smart-phones, and provide customers personalized restaurant and dish recommendation service. According to the related applications, this system can successfully recommend the related restaurants and food information to customers.

Wide Range

With the rapid development of the society, the transportation system has become more complicated and vulnerable. For simulating the real-time traffic condition of the whole city, a wide range of OD matrix data are needed which are hard to collect in whole based on the present conventional methods. The paper raises a feasible design of the traffic simulation platform based on the real-time mobile phone data. The popularity and development of mobile phones make the vast amounts of real-time traffic data can be collected and usable. With the help of the GIS module, dynamic OD traffic generation module and other related modules, the real-time mobile phone data will be converted to the valuable traffic data and applied to the traffic simulation platform.
