Three-dimensional human computer interaction based on 3D widgets for medical data visualization

Three-dimensional human computer interaction plays an important role in 3-dimensional visualization. It is important for clinicians to accurately use and easily handle the result of medical data visualization in order to assist diagnosis and surgery simulation. A 3D human computer interaction software platform based on 3D widgets has been designed in traditional object-oriented fashion with some common design patterns and implemented by using ANSI C++, including all function modules and some practical widgets. A group of application examples are exhibited as well. The ultimate objective is to provide a flexible, reliable and extensible 3-D interaction platform for medical image processing and analyzing.
