【Abstract】 The technology of spatial cam and virtual design are investigated, and a virtual design system of spatial cam based on Visual C++ and OpenGL is developed. The design process can be simulated, the three dimensional real time graphics can be displayed, and the cam parameters can be optimized for practical purposes and output in detail.The interaction with this system facilitates the users to simulate the cam animation and find out or correct the existing errors. The theoretical analysis and experimental results indicate that to adopt this system to design spatial cam enables to obtain the optimum parameters, shorten the design period and reduce the cost. 更多还原
