Linearly interpolates between two vectors.
Interpolates between the vectors a
and b
by the interpolant t
. The parameter t
is clamped to the range [0, 1]. This is most commonly used to find a point some fraction of the way along a line between two endpoints (e.g. to move an object gradually between those points).
When t
= 0 returns a
.
When t
= 1 returns b
.
When t
= 0.5 returns the point midway between a
and b
.
