Bling: A new sketch based 3D model search engine

As the number of 3D models available is increasing rapidly, searching out models from such databases is becoming an eager demand in many fields. In this paper, we present a new search engine called Bling to retrieve 3D models by sketch. Aiming at developing a kind of user interface with which even novice users can draw to search, we employed freehand sketches to create voxel models as query. A novel matching algorithm called volume D2 (VD2) is also adopted to compare generated models with database models. Experiments show that Bling provides a feasible solution for easy-to-use 3D model retrieval.
