ORBITAL TRAJECTORY SIMULATION ON TWIN STARS SYSTEM IN IFS FRACTAL MODEL BASED ON HYBRID ANIMATION METHOD
Abstract: IFS (Iterated
Function Systems) is a method to model fractal object based on affine
transformation functions. The star-like object rotation effect in the IFS
fractal model could be exhibited by using metamorphical method, as a
replacement to the affine rotation method on a non metamorphic animation. The
advantage of a metamorphic animation method over the metamorphic animation
method is that the object's relative position to the fixed point as an absolute
centroid is absolute. Therefore, the rotational effect can be exhibited at any
positions. In addition, it can also be combined with rotational effect of the
local centroid itself around the absolute centroid as a fixed point by the
primitive rotational operation to form an interesting behavior of orbital
trajectory Based on the hybrid of both animation methods, the animation
simulation could be done on orbital trajectory on a twin stars rotating to each
other as a system. Both objects are rotated in the same angular direction, but
started in the opposite position around two closely different fixed points. So,
the orbital trajectory yielded forms an elliptical path. The two similar
objects can be created efficiently by cloning-scaling technique. In general,
the animation method can be modeled as an animation framework.
