【Abstract】 It is introduced the conception of visual simulation, and discussed the key technologies of visual simulation, including the method and theory of the displaying of the 3D scene, polygonal mesh model, collision checking, the particle system and so on. This study takes 3D modeling of multi flow evaluarer and the moving house of well field in the downhole operation visual simulation as examples, and explains the proceed of the 3D modeling of oil well ground facilities and the design of 3D engine for downhole operation visual simulation system.更多还原
