Especially for visualization purposes, these models are needed at several levels of detail (LOD) in fine granular steps that also allow for a smooth transformation from one level to the next to avoid pop-up artifacts. Several methods have been proposed for the automatic generalization of 3D building models that simplify the geometry of given boundary-based models at discrete LODs. In this paper, we present an approach to generate a transformation sequence between two discrete LODs with the purpose to later build a continuous LOD sequence. The method is based on mesh simplification techniques that are extended to a restricted use of edge collapse and vertex move operations applied on triangle meshes augmented by additional breaking lines. The validity of the approach is demonstrated on a case study that is close to reality.
