Closea | The start value. |
b | The end value. |
t | The interpolation between the two floats. |
float The float value as a result from the linear interpolation.
Linearly interpolates between a
and b
by t
with no limit to t
.
The parameter t
is not clamped and a value based on a
and b
is supported. If t
is less than zero, or greater than one, then LerpUnclamped
will result in a return value outside the range a
to b
.
Suppose parameter a
= 0.33f, and b
= 1.5f. If interpolator t
= -0.25f then the return
value is 0.0375f.
Details: The calculation (b
- a
) is 1.17f. This is scaled by 0.25f and a result of
0.2925f is obtained. Subtracting this from a
(because the interpolant t
is negative)
results in 0.0375f.
