Adding Transformation to the Node

TSR (Translation/Scaling/Rotation) are most commonly used in 3D scenario, we provided a class Transform to access these in Aspose.3D Affine transformations include:

  • Translation
  • Scaling
  • Rotation
  • Shear mapping
  • Squeeze mapping

Rotate by Quaternion

// Initialize scene object
Scene scene = new Scene();
// Initialize Node class object
Node cubeNode = new Node("cube");
// Call Common class create mesh using polygon builder method to set mesh instance
Mesh mesh = Common.createMeshUsingPolygonBuilder();
// Point node to the Mesh geometry
cubeNode.setEntity(mesh);
// Set rotation
cubeNode.getTransform().setRotation(Quaternion.fromRotation(new Vector3(0, 1, 0), new Vector3(0.3, 0.5, 0.1)));
// Set translation
cubeNode.getTransform().setTranslation(new Vector3(0, 0, 20));
// Add cube to the scene
scene.getRootNode().getChildNodes().add(cubeNode);
// The path to the documents directory.
String MyDir = RunExamples.getDataDir();
MyDir = MyDir + RunExamples.getOutputFilePath("TransformationToNode.fbx");
// Save 3D scene in the supported file formats
scene.save(MyDir, FileFormat.FBX7500ASCII);

Rotate by Euler Angles

// Initialize scene object
Scene scene = new Scene();
// Initialize Node class object
Node cubeNode = new Node("cube");
// Call Common class create mesh using polygon builder method to set mesh instance
Mesh mesh = Common.createMeshUsingPolygonBuilder();
// Point node to the Mesh geometry
cubeNode.setEntity(mesh);
// Euler angles
cubeNode.getTransform().setEulerAngles(new Vector3(0.3, 0.1, -0.5));
// Set translation
cubeNode.getTransform().setTranslation(new Vector3(0, 0, 20));
// Add cube to the scene
scene.getRootNode().getChildNodes().add(cubeNode);
// The path to the documents directory.
String MyDir = RunExamples.getDataDir();
MyDir = MyDir + RunExamples.getOutputFilePath("TransformationToNode.fbx");
// Save 3D scene in the supported file formats
scene.save(MyDir, FileFormat.FBX7500ASCII);

Custom Transformation Matrix

We can also use Matrix directly:

// Initialize scene object
Scene scene = new Scene();
// Initialize Node class object
Node cubeNode = new Node("cube");
// Call Common class create mesh using polygon builder method to set mesh instance
Mesh mesh = Common.createMeshUsingPolygonBuilder();
// Point node to the Mesh geometry
cubeNode.setEntity(mesh);
// Set custom translation matrix
cubeNode.getTransform().setTransformMatrix(new Matrix4(
1, -0.3, 0, 0,
0.4, 1, 0.3, 0,
0, 0, 1, 0,
0, 20, 0, 1
));
// Add cube to the scene
scene.getRootNode().addChildNode(cubeNode);
// The path to the documents directory.
String MyDir = RunExamples.getDataDir();
MyDir = MyDir + RunExamples.getOutputFilePath("TransformationToNode.fbx");
// Save 3D scene in the supported file formats
scene.save(MyDir, FileFormat.FBX7500ASCII);
