缩放 3D 场景的几何图形

缩放单个 3D 节点或 3D 场景的所有节点的几何图形

开发人员只能缩放 3D 节点或 3D 场景的所有节点的几何图形。为了实现这一点，开发人员可以调用 PolygonModifier 类实例的多个Scale成员。这是缩放所有节点或单个节点的代码示例:

C#

 // scale the model in huge-scene.obj by 0.01 and save it to another file:

Scene scene = new Scene("huge-scene.obj");

// create a Box instance

var box = scene.RootNode.CreateChildNode("box", new Box());

// scale geometries of a single node

PolygonModifier.Scale(box, new Vector3(0.01));

// scale geometries of all nodes

PolygonModifier.Scale(scene, new Vector3(0.01));

scene.Save("scaled-scene.obj", FileFormat.WavefrontOBJ);
