Range detection technique for real time virtual heritage application

Abstract

Simulating real world demand real-time and realism of visual appearance . In most real-time computer graphics applications such as virtual walkthrough, flight simulator and games, maintaining the interactive frame rate and smoothness of movement is utmost important. This is essential to give a user an immersive experience in which it will move very smooth during the navigation in the virtual world. Realism as defined in Chiu et al. (1994), means how far the image can visualize in the users mental can be the same as real experience in the real world. According to Dzwig (1988), to generate the realistic 3D world, the geometric complexity level of 3D model has to be increased and this has been agreed by Ramasubramanian ( 1999). The need for beautiful textures will simultaneously increase the memory usage (Airey 1990)
