a | 起点值。 |
b | 终点值。 |
t | 两个浮点数之间的插值。 |
float 作为线性插值结果的浮点值。
在 a
与 b
之间按 t
进行线性插值,t
没有限制。
参数 t
不受限制,支持基于 a
和 b
的值。如果 t
小于零或大于一,则 LerpUnclamped
生成 a
到 b
范围之外的返回值。
假设参数 a
= 0.33f,并且 b
= 1.5f。如果插值器 t
= -0.25f,则返回
值为 0.0375f。
**详细信息:**计算 (b
- a
) 为 1.17f。此值按 0.25f 进行缩放,获得
结果 0.2925f。将 a
减去此值(因为插值 t
为负)
得到 0.0375f。
