There are many approaches and algorithms that can be used to recognize and synthesize the hands gesture. Each approach has its own advantages and characteristics. This paper describes the usage of Hidden Markov Models (HMM) and Principal Component Analysis (PCA) in recognizing hands gesture by two different researches. The limitations of each techniques and(More)
Virtual Human Character movement is very essential on virtual reality game in order to perform natural or emotional movement. Basically, numerous researchers focusing on movements from input such as: joystick, mouse, and keyboard. The other movement’s concepts come from artificial intelligence as a part of improving interactivity. This paper intends to(More)
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)
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)
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)
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)
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)
This paper brings to iterative selection criteria to improve simple adaptive subdivision surfaces method in handling cracks for triangular meshes. Adaptive subdivision is a method that subdivides only at certain areas of the control mesh. Although subdivision occurs in the selected areas, the quality of produced surfaces can be preserved similar to the(More)
