Title: "A Survey of Sketch-based Modeling Systems"

by

Mr. Lei LI


Abstract:

3D modeling is a foundation stone of computer graphics, however it requires 
substantial time and effort even for professional modelers. Sketch-based 
modeling approaches aim at offering easy-to-use interfaces to the user for 
creating 3D models by drawing only a small number of strokes. Sketches, 
commonly drawn by artists with pen and paper in early conceptual design stages, 
are an accessible medium for conveying ideas and guiding subsequent modeling 
process with traditional modeling software, such as 3DS MAX or SketchUp. Taking 
a sketch as input, sketch-based modeling systems attempt to infer plausible 3D 
geometries by interpreting the user's intentions in the sketch. Unfortunately, 
algorithmic interpretation of a sketch is a challenging task due to ambiguities 
in the sketch. Thus, additional constraints are necessary to aid the 
sketch-to-model conversion process. In this survey, we broadly classify the 
existing sketch-based modeling systems into two categories: modeling with 
low-level geometric constraints and modeling with high-level geometric 
constraints, and review the related modeling techniques in each category. We 
conclude by discussing two interesting research directions for future work.
