Virtual Physics for Virtual Reality
Found in: Theory and Practice of Computer Graphics
By Philip Willis
Issue Date:June 2004
pp. 42-49
We consider the problem of giving virtual reality objects physical behaviour. We wish to do this in a way which allows users to construct new objects from simpler ones and have the correct composite behaviour emerge. Our approach uses a graph structure to ...
 
Demosaicing of Colour Images Using Pixel Level Data-Dependent Triangulation
Found in: Theory and Practice of Computer Graphics
By Dan Su, Philip Willis
Issue Date:June 2003
pp. 16
Single-chip digital cameras use an array of broad-spectrum Charge-Coupled Devices (CCD) overlayed with a colour filter array. The filter layer consists of transparent patches of red, green and blue, such that each CCD pixel captures one of these primary co...
 
Generalised compositing
Found in: Proceedings of the 5th international conference on Computer graphics and interactive techniques in Australia and Southeast Asia (GRAPHITE '07)
By Philip Willis
Issue Date:December 2007
pp. 129-134
We revisit the assumptions behind traditional image compositing techniques. By analysing the process we separate the colour operations from those for coverage and show that this usefully leads to a more general compositing equation than previously used. We...
     
Texture for volume character animation
Found in: Proceedings of the 3rd international conference on Computer graphics and interactive techniques in Australasia and South East Asia (GRAPHITE '05)
By Peiyi Shen, Philip Willis
Issue Date:November 2005
pp. 255-264
We present an approach to texture mapping volume datasets based on multiple semantic constraints. The approach is based on continuous space mappings to ensure good image quality. It requires only one intervention by the user, to determine key points where ...
