ARTransform : Visualization of Three Dimensional Geometric Transformations in Augmented Reality Environment

Three dimensional (3D) geometric transformations are basic and important skills when working in computer graphics related areas. Traditional ways in learning the skills include forcing the 3D results to be demonstrated on 2D output media thus challenge the imaginations of the viewers. This paper presents ARTransform – an augmented reality (AR) application for 3D geometric transformations analysis. ARTransform animates 3D geometric transformations in real environment, which enables the viewers to move around the transforming objects and make closer observations. Graphical user interface control panels are developed to provide userspecified geometric transformations and animations. ARTransform adopts the concept of keeping the learning curve gentle to enable the viewers to spend more time in transformation analysis, thus, user interaction is achieved by conventional input devices via keyboard and mouse. ARTransform is still at its infancy and much work remains to be done. User-test on the application will be carried out when more features are added to the application.
