m-LOMA - a mobile 3D city map
Antti Nurminen · 2006
m-LOMA, mobile LOcation-Aware Messaging Application, is designed to be a mobile portal to location-based information in cities. The user can perform textual searches to location-based content, navigate using 2D maps assisted by a GPS, and leave messages to the environment, or recognize the environment from a 3D map. The 3D map view is the key feature of the m-LOMA system. The m-LOMA client is capable of rendering photorealistic 3D city models with augmented location-based information in a smart phone without hardware rendering support at interactive frame rates. This paper presents the key challenges and solutions in creating this 3D map engine and a lightweight but photorealistic 3D city model.
