Hybrid rotational and revolving simulation of propeller in aircraft with two propellers by fractal animation model: Based on shifting centroid method in double mode from a fixed point

An interesting of hybrid rotational and revolving simulation of aircraft propellers around a fixed point can be accomplished by the modified version of the shifting centroid method in IFS fractal animation model called the shifting centroid method in double mode. To animate a complex object such as an aircraft with two propellers in fractal model, a simple multi-object of fractal can be used instead of a complicated object which is difficult to be build. The multi-object of fractal can be build by the modified version of random iteration algorithm called partitioned-random iteration algorithm. To rotate many objects as components of a multi-object, the primitive rotation method of affine transformation can be used to a certain object independently.
