INTRODUCTION
Three dimensional shape searching refers to the process of shape based retrieval of 3D models from a large database by determining the similarities among 3D shapes.
3D model databases used around the web is growing at a fast speed which makes the pro-blem of 3D searching significant
3D models have become integral component in fields like medicine, architecture,chemistry and entertainment.
How people will search for 3D models?
The simplest approach is to search for keywords in filenames, captions, or context
This approach can fail:
1-when objects are not annotated
2-when objects are annotated with unspecific or derivative keywords
3-when all related keywords are so common
4-when relevant keywords are unknown
In these cases, shape-based queries will be helpful for finding 3D objects.
