minAngle number <optional>
 0 分析最小坡度，角度值
maxAngle number <optional>
 90 分析最大坡度，角度值
colorRange object <optional>
 颜色范围值，键为角度，值为颜色,{50:{r:1,g:0,b:0},90:{r:0,g:1,b:0}}表示0-50度为红色，50-90度为蓝色
useSlopeAnalysis Boolean <optional>
 false 是否使用坡度分析，默认false

Parameters:
Name Type Description
options object {from, to, duration, easing, loop}
Properties
Name Type Description
from object 起始值{position:null,rotation:null,scale:null} 可不设置，不设置就是当前状态
to object 结束值{position:{x,y,z},rotation:{roll,pitch,yaw},scale:{x,y,z},animateOffset:{x,y,z}}
