內插(interpolation)

動作A ------> 動作B

a=0 .................a=1

你的動作(angle[...])

angle[0] = angleOld[0]*(1-a) + angleNew[0]*a;   //內插公式

口訣: 交叉相乘

ex.

a=0, angle[0] 是 angleOld[0]

a=0.1, angleOld[0]*0.9 + angleNew[0]*0.1

a=0.5,  angleOld[0]*0.5 + angleNew[0]*0.5

a=0.9,

a=1, anlge[0] 是 angleNew[0]
