After two years breaks, we invited National College students for summer interns. This year we had two guest students from Toyama National College of Maritime Technology and Ishikawa National College of Technology. It lasted only for a week, but they were very efficient to implement fundamental methods for 3D shape retrieval with Java programming language. This is why I had to add an extra material of Web application GUI interface with Tomcat (version 6.0.18). I wish this experience will brighten their spirits.
