一种可共享三维动画的新方法

针对项目中对三维引擎的要求对骨骼动画进行了研究。提出了一种实现动画共享的方法。方法是给人物的各个关节指定一个位置，所存储各关节的位移量都针对此起始位置，需要共享的动画数据单独存储。由于采用的是相对位移，且是相对角色的，不同角色使用同样动画时，系统会根据角色的伸缩将动画绑定到不同位置，从而实现动画共享。并通过顶点索引法存贮数据，大大降低了运算量。最后实现了三维骨骼动画，并给出了相应的测试数据。

A New Method of Shared 3D Animation

A through research for 3D animation technique with an implementation of 3D engine is done. A new method for sharing 3D skeleton animations is achieved. In this method, every joint of the role is set a position, the displacement amount is only determined by the positioa The animation which needs to be shared is stored independently. The relative displacement just operates against roles, so the animation can be shared. Because when different roles use the same animation, the system can set the animation in different positions based on the motion of the roles. By the storage method of vertex indexing, the complexity of calculation is cut down. At last, the 3D cartoon technique is applied in the 3D engine and some test data is Riven also.
