Adaptive grids: an image-based approach to generate navigation meshes

Akaydın, A.; Güdükbay, U. (S P I E - International Society for Optical Engineering, 2013-02-01)

We propose adaptive grids, an image-based approach for constructing navigation meshes, which are used for path planning. A cellular navigation mesh, called an adaptive grid, is constructed from a top-view range image of a ...
Conservative occlusion culling for urban visualization using a slice-wise data structure

Yılmaz, T.; Güdükbay, Uğur (Academic Press, 2007)

In this paper, we propose a framework for urban visualization using a conservative from-region visibility algorithm based on occluder shrinking. The visible geometry in a typical urban walkthrough mainly consists of partially ...
