The demand for high quality and speed in graphical representations of 3D scenes is continuously increasing. An important aspect of visual realism is real-time processing of transparent objects. In order to provide a realistic solution to be considered for future graphics cards, proposed extensions to the hardware need to be small. In this paper, we propose two new hardware oriented proposals fo...

The creation and rendering of realistic water scenes is one of the challenging tasks in Computer Graphics. To reproduce the illumination and colour inside water bodies an algorithm capable of dealing with media with anisotropic and multiple scattering has to be used. We have developed a simulation system based in the discrete ordinates method to solve the problem of light transport in general p...

In this paper we propose a platform at which any person can perform haka (War Dance) without any previous training. In the intended final system performance is done in front of a simple camera and a sensor system set up. The user will then be able to see his instant virtual haka metamorphosis in a giant screen in front of him. The proposal is to capture the participant’s hand gestures, foot sta...

Projection-based appearances are used in a variety of computer graphics applications to impart different appearances onto physical surfaces using digitally controlled projector light. To achieve a compliant appearance, all points on the physical surface must be altered to the colours of the desired target appearance; otherwise, an incompliant appearance results in a misleading visualization. Pr...
