This paper presents recent experiments on 3D morphing of buildings. A genealogical tree is created out of cross-morphing buildings showing their children and grandchildren. The resulting children-buildings share characteristics of the formal properties of their parents. There are two methods used here to morph buildings: face-to-face mapping and object-to-object mapping. All morphed buildings are shown as real-time animation. A series of experiments will be presented. Some experiments investigate the implementation of architecture or art theories. For example, how would it look like to morph a Hedjuk building into a Le Corbusier building? How would the resulting child look like in a cubist world? Or how would a building look like as it is extrapolated beyond its target and instead of lines and points it is represented as letters and colors? The computer system that was developed by the author for this paper is called "zhapes" and is a Java-based 3D-experimentation system. It resides at the address where it can be downloaded for explorations.
