Study and Design of 3D Virtual Scenes of Virtual Laboratory

摘要

The virtual laboratory is one of the virtual reality applications. This paper carries on research to the three-dimensional scenes of virtual laboratory. Model design of laboratory apparatus adopts the thought of geometry combining with image based on object oriented, and then we encapsulate the models. The design of background of virtual laboratory adopts panoramic technology of cylinder, and finished environment is as good as photo with good quality. And in this paper, the projective geometry principle is adopted to adjust virtual apparatus position and direction, and gradation zone of illumination is adopted to integrate background and virtual apparatus. Finally, the aggrandized virtual environment is formed. So itȁ9; s stronger that the whole experiment interface makes user immerse the experiment.
