abstract

In product design, designers often create a multitude of concept sketches as part of the ideation process. Transforming such sketches to 3D digital models usually require special expertise and effort due to a lack of suitable Computer Aided Design (CAD) tools. Although recent advances in sketch-based user interfaces and immersive environments (such as augmented/virtual reality) have introduced novel curve design tools, rapid surfacing of such data remains an open challenge. To this end, we propose a new method that enables a quick construction of approximate surfaces from a cloud of 3D curves that need not be connected to one another. Our method first calculates a vector field by discretizing the space in which the curve cloud appears into a voxel image. This vector field drives a deformable surface onto the 3D curve cloud thus producing a closed surface. The surface smoothness is achieved through a set of surface smoothing and subdivision operations. Our studies show that the proposed technique can be particularly useful for early visualization and assessment of design ideas.
