Over the last decade, more and more 3D product models
have been used in e-commerce. With the proliferation of
these 3D product models, the traditional text-based search
techniques are not always effective for 3D data. As a result,
the need for the ability to retrieve 3D models from large
product model databases has gained prominence in ecommerce.
Now researchers have present kinds of
approaches to match the similarity among 3D models. These
approaches can be broadly classified into three categories by
the features using in the paper: outline-based 3D model
retrieval [9-12], topology-based 3D model retrieval [13, 14],
and visual-based 3D model retrieval
