Animasyon özelliğini 3D belgesine ekleyin

Aspose.3D for Java animasyonlu sahne oluşturmayı destekler. Bu makale, bir nesneyi taşımak için ön şartları açıklar.

Move Cube’s Position

The Mesh class object is being used in the code. We can create a Mesh class object as narrated there and it’s must animate the local translation property of the node too: Adding the Transformation to the Node.

In Aspose.3D for Java API, animation instance is actually key-frame animation that animates on properties. In order animate properties, you need a CurveMapping instance which maps components of a property to different curves, for example, a Vector3 property can have 3 components X/Y/Z, which will set up three channels in CurveMapping, every channel can have a set of Curve.

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-Java
// Initialize scene object
Scene scene = new Scene();

// Call Common class create mesh using polygon builder method to set mesh instance
Mesh mesh = Common.createMeshUsingPolygonBuilder();

// Each cube node has their own translation
Node cube1 = scene.getRootNode().createChildNode("cube1", mesh);

// Find translation property on node's transform object
Property translation = cube1.getTransform().findProperty("Translation");

// Create a bind point based on translation property
BindPoint bindPoint = new BindPoint(scene, translation);

// Create the animation curve on X component of the scale
KeyframeSequence kfs = new KeyframeSequence();
// Move node's translation to (10, 0, 10) at 0 sec using bezier interpolation
kfs.add(0, 10.0f, Interpolation.BEZIER);
// Move node's translation to (20, 0, -10) at 3 sec
kfs.add(3, 20.0f, Interpolation.BEZIER);
// Move node's translation to (30, 0, 0) at 5 sec
kfs.add(5, 30.0f, Interpolation.LINEAR);
            
bindPoint.bindKeyframeSequence("X", kfs);

kfs = new  KeyframeSequence();
// Move node's translation to (10, 0, 10) at 0 sec using bezier interpolation
kfs.add(0, 10.0f, Interpolation.BEZIER);
// Move node's translation to (20, 0, -10) at 3 sec
kfs.add(3, -10.0f, Interpolation.BEZIER);
// Move node's translation to (30, 0, 0) at 5 sec
kfs.add(5, 0.0f, Interpolation.LINEAR);
            
bindPoint.bindKeyframeSequence("Z", kfs);

// The path to the documents directory.
String MyDir = RunExamples.getDataDir();
MyDir = MyDir + RunExamples.getOutputFilePath("PropertyToDocument.fbx");

// Save 3D scene in the supported file formats
scene.save(MyDir, FileFormat.FBX7500ASCII);

Hedef kamerayı 3D dosyasında kur

Aspose.3D for Java offers to setup the target camera in 3D file. In some file formats, light/camera supports target, which allows the light/camera always facing a specified node, this is useful in animation.

Scene, Camera, Node ve Transform sınıfları kodda kullanılıyor. Scene, Scene.save yöntemini kaydetmek için, tam yol ve FileFormat parametresi ile bir dosya adını kabul eder.

Aşağıdaki örnekte, hedef ve kamera 3D dosyasında kurulur:

// The path to the documents directory.
String MyDir = RunExamples.getDataDir();
// Initialize scene object
Scene scene = new Scene();
// Get a child node object
Node cameraNode = scene.getRootNode().createChildNode("camera", new Camera());
// Set camera node translation
cameraNode.getTransform().setTranslation(new Vector3(100, 20, 0));
((Camera)cameraNode.getEntity()).setTarget(scene.getRootNode().createChildNode("target"));
MyDir = MyDir + "camera-test.3ds";
scene.save(MyDir, FileFormat.DISCREET3DS);
