Camera.cameraToWorldMatrix

説明

カメラ空間からワールド空間に変換する行列（読み取り専用）。

特定のカメラ空間のポイントがワールド内のどこにあるのかを計算するのに使用します。

Note that camera space matches OpenGL convention: camera's forward is the negative Z axis. This is different from Unity's convention, where forward is the positive Z axis.

// Draw a yellow sphere in scene view at distance/
// units along camera's viewing direction.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    public float distance = -1.0F;
    void OnDrawGizmosSelected()
    {
        Matrix4x4 m = Camera.main.cameraToWorldMatrix;
        Vector3 p = m.MultiplyPoint(new Vector3(0, 0, distance));
        Gizmos.color = Color.yellow;
        Gizmos.DrawSphere(p, 0.2F);
    }
}
