A Parallax Mapping based Approach for Building Facade Modelling
The complex structure of modern urban building surfaces makes it very difficult to model building surfaces in the refined way,and how to quickly reconstruct building surfaces has become a research focus in the field of building modeling.We propose a parallax mapping-based building surface modeling method,which provides a set of 2D primitive library of building surface components that can express the appearance of the building surface,simulates the details of the building surface by extracting the primitives in the primitive library,and extracts the required texture data according to the combinations of the primitives,and adds the details of the building surface based on the parallax mapping,and u-ses the loose cone order map to accelerate the RayMatching process of the parallax mapping in the parallax mapping.The RayMatching process of parallax mapping is accelerated by using a loose cone step map during the parallax mapping process.The final result is controllable and editable.The experimental results show that the method can efficiently gen-erate building models with sufficient surface details,quickly modify the modeling results,and the modeling process is friendly to non-expert users.
