We present a novel compression scheme for high dynamic range textures, targeted for hardware implementation. Our method encodes images at a constant 8 bits per pixel, for a compression ratio of 6:1. We demonstrate that our method achieves good visual fidelity, surpassing DXTC texture compression of RGBE data which is the most practical method on existing(More)
This paper presents the design and prototype implementation of a location-based service aimed for hikers. Maps and navigation in urban areas are already well-researched topics but it can be argued that greater demands are placed on location-based services in non-urban areas -- a field which has not been researched in detail yet. Studying these demands more(More)
