In this paper, a light weight architecture modeling approach based on feature wires is proposed, which is called Fe-Wires. The approach is a procedural modeling method based on shape grammar. In the method, 3D models are reconstructed based on inputting and manipulating feature wires of architecture objects to overcome the interaction weakness of original rule-based approaches. To interactively tuning complex architecture models, we present a global deformation model which uses axis-aligned spring constraints. Different from previous nonlinear optimization methods, our approach only need to solve a convex quadratic problem which can be efficiently solved in real time. The presented experiments show that our method can be applied on the real applications for interactive modeling inner and outer part of buildings.
