  We describe a guided proceduralization framework that optimizes geometry
processing on architectural input models to extract target grammars. We aim to
provide efficient artistic workflows by creating procedural representations
from existing 3D models, where the procedural expressiveness is controlled by
the user. Architectural reconstruction and modeling tasks have been handled as
either time consuming manual processes or procedural generation with difficult
control and artistic influence. We bridge the gap between creation and
generation by converting existing manually modeled architecture to procedurally
editable parametrized models, and carrying the guidance to procedural domain by
letting the user define the target procedural representation. Additionally, we
propose various applications of such procedural representations, including
guided completion of point cloud models, controllable 3D city modeling, and
other benefits of procedural modeling.
