sourcefn lerp(self, rhs: Self, s: Self) -> Self
fn lerp(self, rhs: Self, s: Self) -> Self
Performs a linear interpolation between self and rhs based on the value t.
When t is 0, the result will be self. When t is 1, the result
will be rhs. When t is outside of the range [0, 1], the result is linearly
extrapolated.
sourcefn inverse_lerp(a: Self, b: Self, v: Self) -> Self
fn inverse_lerp(a: Self, b: Self, v: Self) -> Self
Returns v normalized to the range [a, b].
When v is equal to a the result will be 0. When v is equal to b will be 1.
When v is outside of the range [a, b], the result is linearly extrapolated.
a and b must not be equal, otherwise the result will be either infinite or NAN.
sourcefn remap(
self,
in_start: Self,
in_end: Self,
out_start: Self,
out_end: Self,
) -> Self
fn remap( self, in_start: Self, in_end: Self, out_start: Self, out_end: Self, ) -> Self
Remap self from the input range to the output range.
When self is equal to in_start this returns out_start.
When self is equal to in_end this returns out_end.
When self is outside of the range [in_start, in_end], the result is linearly extrapolated.
in_start and in_end must not be equal, otherwise the result will be either infinite or NAN.
