In this paper we introduce a new algorithm for simplification of polygonal meshes. It generates a variable resolution structure called hierarchical 4-K mesh. This structure is a powerful representation for non-uniform level of detail that, among other things, allows simple and efficient extraction of conforming meshes.

A new algorithm to identify the neighbours of polygons on 4-connected raster images of 2D polygonal networks is presented in this paper. It is mainly based on mathematical morphology operators and can be indistinctively applied to networks of tri and tetravalent nature (with three and four edges at each vertex, respectively). The algorithm is tested on a varied set of polygonal terrains occurri...

We consider the problem of planning smooth paths for a vehicle in a region bounded by polygonal chains. The paths are represented as B-spline functions. A path is found by solving an optimization problem using a cost function designed to care for both the smoothness of the path and the safety of the vehicle. Smoothness is defined as small magnitude of the derivative of curvature and safety is d...
