Approximate ambient occlusion for trees
Natural scenes contain large amounts of geometry, such as hundreds of thousands or even millions of tree leaves and grass blades. Subtle lighting effects present in such environme...

Edge-Based Markerless 3D Tracking of Rigid Objects
In this paper we present a real-time 3D object tracking algorithm based on edges and using a single pre-calibrated camera. During the tracking process, the algorithm is continuous...

On the complexity of graph cuboidal dual problems for 3-D floorplanning of integrated circuit design
This paper discusses the impact of migrating from 2-D to 3-D on floorplanning and placement. By looking at a basic formulation of graph cuboidal dual problem, we show that the 3-...

Using VRML to share large volumes of complex 3D geoscientific information via the Web
Scientists within Geoscience Australia (GA) create complex 3D models of geological structures, using specialised 3D modelling software. Very few people outside GA have access to t...
