public static function Slerp(a: Vector3, b: Vector3, t: float): Vector3;
public static Vector3 Slerp(Vector3 a, Vector3 b, float t);

Parameters

Description

球状に 2 つのベクトル間を補間します

tab の間を補間します。この関数と、直線で補間する (別名 "leap")の違いは、ベクトルは方向としてではなく、空間の位置として扱われることです。 返されたベクトルの方向は角度によって補間され magnitudefromto の大きさの間で補間されます。

値は [0...1] の範囲に制限されます。

	// Animates the position in an arc between sunrise and sunset.
	
	var sunrise : Transform;
	var sunset : Transform;
	
	// Time to move from sunrise to sunset position, in seconds.
	var journeyTime = 1.0;
	
	// The time at which the animation started.
	private var startTime: float;
	
	
	function Start() {
		// Note the time at the start of the animation.
		startTime = Time.time;
	}
	
	
	function Update () {
	    // The center of the arc
	    var center = (sunrise.position + sunset.position) * 0.5;
	    // move the center a bit downwards to make the arc vertical
	    center -= Vector3(0,1,0);
	
	    // Interpolate over the arc relative to center
	    var riseRelCenter = sunrise.position - center;
	    var setRelCenter = sunset.position - center;
	    
	    // The fraction of the animation that has happened so far is
	    // equal to the elapsed time divided by the desired time for
	    // the total journey.
	    var fracComplete = (Time.time - startTime) / journeyTime;
	    transform.position = Vector3.Slerp(riseRelCenter, setRelCenter, fracComplete);
	    transform.position += center;
