Transform

Example: com.aspose.threed (aspose-3d-foss)

Transform bir nesnenin konumunu, yönelimini ve ölçeğini kontrol eder Node 3D sahnesinde. Her düğüm tam olarak bir Transform, şu aracılığıyla erişilir node.getTransform().

public class Transform extends A3DObject

Kullanım Örnekleri

Bir Düğümü Konumlandırma

import com.aspose.threed.Scene;
import com.aspose.threed.*;

Scene scene = new Scene();
Node node = scene.getRootNode().createChildNode("box");

// Using fluent setters
node.getTransform().setTranslation(5.0, 0.0, -3.0);

// Or via property setter
node.getTransform().setTranslation(new Vector3(5.0, 0.0, -3.0));

Euler Açılarıyla Döndürme

Scene scene = new Scene(); Node node = scene.getRootNode().createChildNode(“rotated”);

// Rotate 45 degrees around Y axis node.getTransform().setEulerAngles(0.0, 45.0, 0.0);

// Chain multiple operations node.getTransform() .setTranslation(2.0, 0.0, 0.0) .setScale(2.0, 2.0, 2.0);


### Quaternion ile Döndürme

```java
import com.aspose.threed.Scene;
import com.aspose.threed.*;
import com.aspose.threed.*;

Scene scene = new Scene();
Node node = scene.getRootNode().createChildNode("q-rotated");

// 90 degrees rotation around the Y axis
double halfAngle = Math.toRadians(45);   // half the total rotation
Quaternion q = new Quaternion(Math.cos(halfAngle), 0.0, Math.sin(halfAngle), 0.0);
node.getTransform().setRotation(q);

System.out.println("Euler: " + node.getTransform().getEulerAngles());   // synced automatically

Ölçek ve Konumu Birlikte Ayarlama

Scene scene = new Scene(); Node node = scene.getRootNode().createChildNode(“big-offset”);

node.getTransform() .setTranslation(10.0, 0.0, 0.0) .setScale(3.0, 3.0, 3.0) .setEulerAngles(0.0, 90.0, 0.0);


### Geometrik Ofset (Pivot Ofseti)

Geometrik dönüşümler, çocuğu düğümleri etkilemeden geometrinin düğümün pivotuna göre konumunu değiştirir; bir mesh'i düğüm içinde ortalamak için faydalıdır:



Scene scene = new Scene();
Node node = scene.getRootNode().createChildNode("centered-mesh");

// Shift the mesh half a unit down so its base sits at y=0
node.getTransform().setGeometricTranslation(0.0, -0.5, 0.0);

Scene scene = new Scene(); Node node = scene.getRootNode().createChildNode(“m”); node.getTransform().setTranslation(1.0, 2.0, 3.0); node.getTransform().setEulerAngles(0.0, 45.0, 0.0);

Matrix4 m = node.getTransform().getTransformMatrix(); System.out.println(m.getClass().getName()); // com.aspose.threed.Matrix4
