Using blocks to construct 3D shapes and create transformation animations

摘要

The objective of this research is to develop methods by which we can use blocks toapproximate the shapes of 3D objects and to generate shape transformation animations.Two graphic tools are developed. One assists the animator in constructing 3D shapeswith bricks of different sizes and matching up the different shapes. The other tool helpsthe animator generate a transformation animation of those bricks. Using polygon shapedata, these tools can procedurally place the bricks and control their animation. Severaldifferent methods for animation are introduced. Those methods provide different ways togenerate animation paths of the blocks. The no path animation and the straight pathanimation are easy for the animator to create and the animation time is easily controlled.The flocking animation will provide more interesting effect.
