EFFICIENT RENDERING OF HIGH-DETAILED OBJECTS USING A REDUCED MULTI-RESOLUTION HIERARCHY
Mathias Holst, Heidrun Schumann · 2006
In the field of view-dependant continuous level of detail of triangle-meshes it is often necessary to extract the current LOD triangle by triangle. Thus, triangle strips are only of very limited use, or only usable with a high effort. In this work a method is proposed that allows a stepwise reduction of a great, fine stepped LOD hierarchy by merging nodes. The result of this process is a reduced hierarchy, which allows the extraction of many neighboring static triangles in one step, so that triangle strips are applicable more efficiently. We show that this results in a significant decimation of processed vertices without loosing a smooth LOD transition.
