Optimization of Animation Curve Generation Based on Hermite Spline Interpolation

Abstract

Computer animation is the combination of computer graphics and art field. In computer animation design, the adjustment of route for the animation object movement is a time consuming work for the designers. It is not only related to the generation of motion path curve, but also related to the speed smoothness of key frames. Based on the methodology of Hermite spline interpolation, this paper proposes a method to adjust the curve tangent vector length by considering the parameter of key frame, and use this method to relieve the unevenness of animation speed. Experimental results demonstrate that this method can improve the movement effect of animation route design efficiently.
