    Methodologies for Connected Structured Idealized Ice Crystal Growth Models
    (The Eurographics Association, 2011) El-Alem, Yousef; Roberts, Jonathan C.; R. Laramee and I. S. Lim
    Ice crystals are beautiful and intricate shapes. Our goal is to create ice crystal and other models with similar structure and render them in three-dimensions. Many of the current algorithms apply complex physics-based simulation algorithms to simulate the crystal growth, most are two-dimensional forms, and importantly they are made up of many disconnected parts (pixels); consequently they cannot be easily stored as a single model. However, our approach is to generate visually appealing 3d structures, rather than accurately model reality, that are geometrically connected together to form one connected model. These idealized structures can be easily stored, manipulated and included with other 3d-models and into virtual environments. This work is part of a larger project, thus in this poster presentation we merely describe several alternative methodologies to achieve this effect.

    Using a Kinect Interface to Develop an Interactive 3D Tabletop Display
    (The Eurographics Association, 2011) Cenydd, Llyr ap; Hughes, Chris J.; Walker, Rick; Roberts, Jonathan C.; R. Laramee and I. S. Lim
    While display technology has advanced significantly in recent years, interaction techniques are still tied to the mouse and keyboard paradigm. While for many tasks this may still be appropriate, allowing systems to recognise and respond to user gestures and motions has enormous potential for natural methods of interaction with virtual media. Traditional methods for pose recognition involve using cameras to track the position of the user. This can be very challenging to complete accurately in a variety of environments where objects may be occluded and the lighting conditions can change. Further, to accurately determine the depth of objects in a scene requires a much more complicated and carefully calibrated system. In this research we prototyped a 3D tabletop display and explored the Kinect game controller as a possible solution to tracking the pose and gesture of a user interacting with our display.
