This paper presents a method for fast-approximate collision detection between 3D models <i>S</i> undergoing rigid body motion. To enclose a 3D model in as tight as possible, we propose an approach known as oriented convex polyhedra <i>R</i>(<i>S</i>). By surrounding the 3D models tightly, the veracity of detected collision can be improved. It is known that(More)
Problem statement: Many approaches have been proposed in previous such as the classic sequential connected components labeling algorithm which is relies on two subsequent raster-scans of a binary image. This method produced good performance in terms of accuracy, but because of the implementation of the image processing systems now requires faster process of(More)
An unorganized point is a discrete point that represents a data for a 3d object. This unorganized data need to handle on the way to represent a piecewise of 3d object which is able to produce a smooth surface at the crease and boundary. Various methods have been purpose for subdivision scheme, but none of this method capable to produce a good sharp feature(More)
During panic situation, it is not necessarily the crowd will act as a &#x02018;crowd&#x02019; but rather as a group of individual. As part of the crowd in panic situation, there will be a group of individuals who will act accordingly like following leader, relatives or friends. The existing crowd behaviour theories in panic situation comprise of not only(More)
Interactivity and immersiveness are important keys on exploration virtual reality game. Numerous researchers concentrate to augment visual acuity in order to get sensible visualization and animation. In addition, acoustic has also became other aspects to enhance immersiveness of virtual reality game. Recently, there is an issue involving haptic as part of(More)
Performing and detecting object interference or collision detection in urban environment simulation is always challenging problem for researchers to come out with fast and efficient collision detection algorithm. Most of previous method seems trying to tackle the problems of involving specific geometric models colliding pairs with restricted rules and(More)
Performing fast and accurate collision detection between geometric models is still most open problems in modeling, robotics, manufacturing and computer-simulated environments. Most of previous method seems to have their own specification and restricted to a specific geometric models. For example, convex polytopes tend to solve accuracy problems but left(More)
The most challenging task in developing surface modelling is to make the look of 3D object surface realistic such as a real object. To achieve this objective, three main issues that must be considered are the number of polygon, quality of the surface and time. A smooth surface is a key factor to make realistic look of 3D object in the virtual environment.(More)
Crowd systems are widely being exploited in a number of virtual environment applications such as games, virtual world and entertainment. These kinds of applications can provide the immersive feeling into the static scenes and therefore enhancing the reality of the systems. The problems involved in crowd modelling when we only focus on the crowds. For(More)
