Cyber Heart: The Employment of an Iterative Design Process to Develop a Left Ventricular Heart Graphical Display
Found in: Cyberworlds, International Conference on
By C. Reginald Jegathese, Goo Lay Guan, L. Antony Rajiv, Eddie Y. K. Ng, Dhanjoo Ghista, Edmond C. Prakash
Issue Date:December 2003
pp. 237
This paper presents a model-based representation of the heart shape, and dynamics. The left ventricle (LV) of the heart is constructed as a mathematical model, close to the shape of actual LV. The model is made suitable for simulating the deformation of th...
 
A New Physical Model with Multilayer Architecture for Facial Expression Animation Using Dynamic Adaptive Mesh
Found in: IEEE Transactions on Visualization and Computer Graphics
By Yu Zhang, Edmond C. Prakash, Eric Sung
Issue Date:May 2004
pp. 339-352
<p><b>Abstract</b>—This paper presents a new physically-based 3D facial model based on anatomical knowledge which provides high fidelity for facial expression animation while optimizing the computation. Our facial model has a multilayer b...
 
Hierarchical Face Modeling and Fast 3D Facial Expression Synthesis
Found in: Graphics, Patterns and Images, SIBGRAPI Conference on
By Yu Zhang, Edmond C. Prakash, Eric Sung
Issue Date:October 2002
pp. 357
This paper presents a new hierarchical facial model that conforms to the human anatomy for realistic and fast 3D facial expression synthesis. The facial model has a skin/muscle/skull structure. The deformable skin model uses a kind of nonlinear springs to ...
 
Real-Time Physically-Based Facial Expression Animation Using Mass-Spring System
Found in: Computer Graphics International Conference
By Yu Zhang, Edmond C. Prakash, Eric Sung
Issue Date:July 2001
pp. 0347
Abstract: In this study, we propose a physically-based approach based on anatomical knowledge for real-time facial expression animation. The facial model incorporates a physically-based approximation to facial skin and a set of anatomically-motivated facia...
 
Designing a Multi-user 3D Environment System
Found in: Information Visualisation, International Conference on
By Pham Minh Tri, Edmond C. Prakash
Issue Date:July 2001
pp. 0697
Abstract: This study developed a multi-user 3D virtual environment system. The system must achieve two goals:Portability: it can be embedded to any kind of platform. Coherence with other system: it can reuse shared objects like worlds and avatars from othe...
 
SinusCone - A ThetaPhi Algorithm for Human Arm Animation
Found in: Information Visualisation, International Conference on
By Huang Jing, Edmond C. Prakash
Issue Date:July 2000
pp. 318
Arm animation algorithms are often categorized by their constraint expansion strategy. One option is the geometric bounding polygon-cone strategy, a simple containment search strategy that traverses the search space in the order in which successor-bounding...
 
Novel moving target search algorithms for computer gaming
Found in: Computers in Entertainment (CIE)
By Edmond C. Prakash, Peter K. K. Loh
Issue Date:June 2009
pp. 1-8
In a computer game, equipping a bot with a suitable algorithm to locate a human player is difficult. Besides the unpredictable moves made by the player, an unexplored map region poses additional constraints such as new obstacles and pathways that the bot n...
