Technology of virtual reality system Realistic real-time rendering technology were reviewed

  1. The introduction
     
     
    Virtual reality system techniques include (1) stereo display technology, (2) environment modeling .including geometric modeling, Physical modeling, behavior modeling , (3) realistic real-time rendering technology .including realistic rendering technology, Based on the geometry of the real-time rendering technology, the real-time rendering technology based on image (4) 3d   virtual sound
    Implementation technology  include the role of  3d virtual sound, the characteristics of  3d virtual sound, speech recognition and language Sound synthesis technology  (5) natural interaction and sensing technology real-time collision detection technology, 6,) draw the line Art.

Realistic real-time rendering is under current graphics algorithm and hardware constraints is put forward after a certain time Into realistic rendering technology. The meaning of "authenticity" including geometric sense of reality, realism and light behavior really Feeling.Geometric realistic refers to describe the objects in the real world really have very similar geometry appearance behavior Sensing refers to establish the object to the observer, in some sense is completely true .realistic light refers to die Type objects interact with light source brightness and light and shade is consistent with the real world in the image.The "real time" Meaning includes the motion object position and posture of the real-time calculation and dynamic rendering  picture updates to the human eye Observation is less than the degree of scintillation and the system to respond to user input can immediately and produce corresponding to scene .And event synchronization.Because of the complexity of the to describe the real world and the software and hardware condition such as constraints , only through the loss of a certain performance to achieve the purpose of rendering realistic image in real time.
