options :

Name	Type	Default	Description
color	Color	Color.YELLOW	optional 颜色
totalFrame	Number	45	optional 总的帧数，表示整个 OD 线循环一次需要消耗的帧数，该参数 越大 OD 线持续时间越长,可以简单按照 60Fps/s 帧数与时间进行换算.
alphaStep	Number	0.1	optional 透明度间隔步长
lengthRatio	Number	0.03	optional 动态效果线长度与自身长度的比率，取值范围 [0.0, 1.0].

Parameters

Name	Type
options?	ODLineMaterialPropertyOptions

Returns

ODLineMaterialProperty
