Method and apparatus for transforming two-dimensional building data to three-dimensional building data in real time and method and apparatus for three-dimensionally visualizing two-dimensional building data in real time
Keechang Lee,Do-kyoon Kim,Jeonghwan Ahn,Shin-Jun Lee,Hee-sae Lee +4 more
- 21 Jul 2005
TL;DR: In this paper, a method for transforming two-dimensional building data to 3D building data in real-time is presented, based on determining a relative distance between a building and a reference point, and selecting a visualization scheme for the building according to the determined relative distance.
