Info

  • top row : albedo = 1.0, metallic = 1.0, roughness = 0.0->1.0
  • bottom row : albedo = 0.5, metallic = 0.0, roughness = 0.0-> 1.0
  • Tone Mapping : Linear clamp

Unity での数学計算のメモ

// 向きをローカル座標系からワールド座標系へ変換
Vector3 world_dir = Camera.main.transform.TransformDirection( local_direction );

// 特定の向きに少しずつ回転させる
Quaternion target_rot = Quaternion.LookRotation( world_dir );
transform.rotation    = Quaternion.RotateTowards( transform.rotation, target_rot, rotationSpeed * Time.deltaTime );

// 特定の向きを向かせる
Quternion quat;
quat.SetLookRotation( world_dir );

// ローカル座標系を設定
GameObject tmp       = (GameObject) Instantiate( prefab, Vector3.zero, Quaternion.Identity );
tmp.transform.parent = hoge.transform;
tmp.transform.localPosition = new Vector3( 0.0, 1.0, 0.0 );
tmp.transform.localRotation = Quaternion.Euler( 90.0f, 0.0f, 0.0f );

// 球面座標系
float horizon_angle = Mathf.Repeat( horizon_angle, 0.0f, 360.0f );
float vertical_angle = Mathf.Clamp( vertical_angle, -20.0f, 50.0f );
Quaternion look_quat = Quaternion.Euler( vertical_angle, horizon_angle, 0.0f );

// カメラの設定
Vector3 camera_offset_pos = look_quat * new Vector3( 0.0,f 0.0f, - look_dist );
Vector3 camera_pos        = look_at_pos + camera_offset_pos;
transform.LookAt( look_at_pos );

Notes of character controller in Unity

// v = v0     + a   * t;
// x = v0 * t + 0.5 * a * t^2;

// Δv = a * Δt
world_velocity.y -= gravity * delta_time;

// Δx = v * Δt
characterController.Move( world_velocity * delta_time );
