3D structure of proteins deeply takes part in the expression of the protein. Molecular surfaces of the protein generally have very complex and bumpy shapes. It is well-known that functions of proteins strongly appear in the bumpy parts of the molecular surfaces. We propose a visual interface to effectively visualize the partial reliefs of molecular surfaces of proteins. This technique assumes that molecule surfaces are approximated as triangular meshes. It first extracts groups of triangles

The presented technique then visualizes the clustering results applying a hierarchical data visualization technique "HeiankyoView", as a visual interface to explore the clustered partial reliefs.
