Intent-driven model synthesis

This paper presents an intent-driven model synthesis method. The method introduces an interactive straight prismatic construction space to realize the structure and shape variation of the example model simultaneously. The construction space defines the global size and the local shape feature of the desired model. Users can draw a closed curve and some skeleton lines by a sketch-based interface to design the construction space. Our algorithm first uses a quadrangulation algorithm to create a subdivision plane with the same contour as the closed curve. And the drawn skeleton lines control the local orientation of split units in the plane. Then it creates the construction space by sweeping the subdivision plane. Finally, it fills the construction space with the deformed model pieces while maintaining the generalized adjacent constraints, which are defined according to the example model. We demonstrate the effectiveness of the approach on large-scale complex models such as architecture, mountains.
