BabylonJS - 比例

縮放基本上意味著以統一的比例增加或減少物件的大小。我們現在考慮一個例子，在這個例子中，我們將在 x 或 y 或 z 軸上增加/減少物件的大小。

            var light = new BABYLON.PointLight("Omni", new BABYLON.Vector3(0, 100, 100), scene);

            var boxa = BABYLON.Mesh.CreateBox("BoxA", 1.0, scene);
            boxa.position = new BABYLON.Vector3(0,0.5,0);

            var boxb = BABYLON.Mesh.CreateBox("BoxB", 1.0, scene);
            boxb.position = new BABYLON.Vector3(3,0.5,0);		
            boxb.scaling = new BABYLON.Vector3(2,1,2);

            var boxc = BABYLON.Mesh.CreateBox("BoxC", 1.0, scene);
            boxc.position = new BABYLON.Vector3(-3,0.5,0);
            boxc.scaling = new BABYLON.Vector3(2,1,2);

            var boxd = BABYLON.Mesh.CreateBox("BoxD", 1.0, scene);
            boxd.position = new BABYLON.Vector3(0,0.5,3);
            boxd.scaling = new BABYLON.Vector3(2,1,2);

            var boxe = BABYLON.Mesh.CreateBox("BoxE", 1.0, scene);
            boxe.position = new BABYLON.Vector3(0,0.5,-3);
            boxe.scaling = new BABYLON.Vector3(2,1,2);

            var ground = BABYLON.Mesh.CreateGround("ground1", 10, 6, 2, scene);
            ground.position = new BABYLON.Vector3(0,0,0);
            return scene;
         };
         var scene = createScene();
         engine.runRenderLoop(function() {
            scene.render();
         });
      </script>
   </body>

演示

說明

我們以 2、1、2 的值按 x、y 和 z 方向進行了縮放，並使用 new BABYLON.Vector3(2,1,2) 進行縮放。
