【摘要】 为了直观准确地记录和计算空间骨架结构的状态,提出一种仿生关节链球坐标系.对于待求活动关节,在已知与其相连的前两节节棍位置状态的前提下,利用当前节棍的长度值和链球坐标系下的2个角度值来精确计算关节新位置的三维笛卡儿坐标值.最后结合高维仿生信息学理论的应用,证明了采用该坐标系对骨架结构进行的刻画可以逼真地反映状态上细微的、连续的变化,无冗余信息,比传统方法参数少、速度快、应用范围广,可生成丰富的姿态,有利于艺术创作.更多还原

【Abstract】 This paper proposes a biomimetic articulated chain-sphericity coordinate to record and calculate states of spatial skeleton intuitively.For the unknown joint,once states of two forward conjoint sticks are got,we can obtain the new 3D Cartesian coordinate values accurately by using length of stick connected directly and two angles in the new coordinate.The applications based on high-dimensional biomimetic informatics show that this coordinate can reflect subtle and continuous variation of spatial skeleton.Comparing with traditional ways this method has advantages of faster speed and wider application range with few parameters.It is instructive and non-redundancy.更多还原
