Nowadays, 3D point cloud of real buildings, or even a real town, can be
obtained by using LiDAR or such other devices. These 3D point clouds
can be used to construct virtual buildings, or even a whole virtual
town in a cyber space. However, it is hard to visualize such point
clouds effectively because of their large data size. In this paper, we
propose an interactive visualization using octree structure. Users can
switch resolutions and focusing areas interactively. Also, we propose
a high speed path detection algorithm, which can help to compose an
effective camera work for wandering through a virtual town. |
