aab is an automatic composer of forms reminiscent of engineering aesthetics. aab generates solid-void arrangements following a fractal(self-similar) generation pattern. Any level of detail, from large, solid blocks, to fine, intricate yet abstract artefacts and arrangements can be observed.

The generation process is unassuming and straightforward. No stylistic choices are made a priori, all features have a probability of occurring through the repetition of countless slicing and subdivision operations. Controls that affect the probability of each operation can be used to 'steer' the generation process towards the desired features. The program simply assumes a solid rectangular volume which it recursively and randomly subdivides in parallel planes (like an L-System) or grids, removing random volumes in the process. Afterwards, it does a little bit of post-processing, creating holes and gaps between the volumes and presents the result as a 3D model. It is also possible to export compositions in .DXF format.

The new version of aab, released 04/2011 features an updated, easy to use interface.
