The Research And Application Of Virtual Fish-farming System Based On Virtual Reality

The background of the paper is Virtual fish-farming based on Virtual RealitySystem. In the paper, Author discusses mainly how to research, develop andimplement Virtual Reality system. Firstly, introduces The development of VirtualReality and The Basic graphic knowledge of 3D animation and the 3D animationprogramming kit –Direct 3D.Next describes various key technology about Virtualfish-farming: A kind of Algorithm about swimming of a group of fish and particleSystem based on Direct3D and math-model of Virtual fish-farming, then Theimplementation details about fish-farming: Such as The creation and swimming offish, the visualization of aquatic grass etc. lastly, The framework of whole systemand the description of each module of the system are given, In order to present thechanges during fish-farming process scientifically, an algorithm for acquiring timebased on CPU frequency and some functions are used。The system is developed based on Visual C++ combined with DirectX.
