threejs 坐標體系

threejs的坐標體系

// 平面不旋轉的效果

plane.rotation.x = 0;

plane.position.x = 0;

plane.position.y = 0;

plane.position.z = 0;

 

// 逆時針旋轉90°

plane.rotation.x = -0.5*Math.PI;

plane.position.x = 0;

plane.position.y = 0;

plane.position.z = 0;

 

plane.rotation.x = -Math.PI/4;

plane.position.x = 0;

plane.position.y = 0;

plane.position.z = 0;

 

• y軸和z軸的位置要互換（上圖）

  

   

• 上圖中紅綠藍所在的方向是坐標軸的正方向
