In the computer animation processing process, campaign object action of smooth and store of space is pair contradictions body, for address the contradictions, used has will campaign object of local part from overall in the separation out, and by actual features requirements respectively for programming processing, articles in the by discussion of technology and method in helicopter flight experimental in the are has application, completed has object of built die, and displayed and in keyboard or mouse control for corresponding of operation. Experiment first a helicopter using 3DMAX picture for pretreatment, the helicopter into the propeller blades and tail blades and fuselage on three parts, in the form of graphic blocks are stored separately in the 3DS file. Then use Visual c together with open source graphics API OpenGL(Application Programming Interface Open Graphics Library short in writing as OpenGL below), such as pan, zoom, and rotate functions programming helicopters taking off and landing, helicopter blades(propeller) rotate and texture, using OpenGL support double buffering technique to achieve the smooth operation of the animation. Experiments have shown that technical feasibility, methods, processing can be run in many objects, such as running in the car, body and wheels split and separately to similar treatment.
