public static Vector3 Lerp (Vector3 a, Vector3 b, float t);

説明

直線上にある 2 つのベクトル間を補間します

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.
