In 3D computer graphics, it has been an important issue to describe a virtual object realistically and show it in a physically correct manner. Unlike the virtual reality(VR), the augmented reality (AR) is an environment containing virtual and real objects simultaneously. However, the difference in motion between the virtual and real objects is obvious, which makes it hard for AR to be realistic and...
This paper presents an architecture to support fast prototyping of augmented reality systems, based on virtual reality. The architecture defines simulation services separated from other aspects of the system. These services support incremental evolution of simulated prototypes into nonsimulated systems. Focus is also placed on user interaction,through the definition of an interaction architecture...
A new real-time point-based rendering method of large outdoor scenes is presented. Based on our interactive subdivide method, polygonal trees and other vegetation were converted to point-based models, and then different level of details of trees and other vegetation were created using hierarchical clustering. Different level of details of terrain were created using diamond tree backbone of ROAM2.0...
