GlobalTransform

Methods

GlobalTransform je iba na čítanie snímka Nodesvetový priestor transformácie. Získava sa pomocou node.getGlobalTransform() a odráža zloženie vlastného uzla Transform s transformáciou každého predka až po koreň scény.

Všetky vlastnosti sú iba na čítanie. Ak chcete zmeniť pozíciu uzla, upravte lokálny Transform namiesto toho.

import com.aspose.threed.GlobalTransform;

GlobalTransform zvyčajne sa neinstancuje priamo; získate ho z node.getGlobalTransform().

Methods

NameTypeAccessDescription
translationVector3ReadGets the translation.
scaleVector3ReadGets the scale.
eulerAnglesVector3ReadGets the rotation represented in Euler angles, measured in degree.
rotationQuaternionReadGets the rotation represented in quaternion.
transformMatrixMatrix4ReadGets the transform matrix.
SignatureDescription
GlobalTransform()Initializes a new instance of the GlobalTransform class.
GlobalTransform(matrix: Matrix4)Initializes a new instance of the GlobalTransform class with the specified matrix.
getTranslation() → Vector3Gets the translation.
getScale() → Vector3Gets the scale.
getEulerAngles() → Vector3Gets the rotation represented in Euler angles, measured in degree.
getRotation() → QuaternionGets the rotation represented in quaternion.
getTransformMatrix() → Matrix4Gets the transform matrix.

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


Scene scene = new Scene();

// Create a parent node at (10, 0, 0)
Node parent = scene.getRootNode().createChildNode("parent");
parent.getTransform().setTranslation(new Vector3(10.0, 0.0, 0.0));

// Create a child node at (5, 0, 0) relative to parent
Node child = parent.createChildNode("child");
child.getTransform().setTranslation(new Vector3(5.0, 0.0, 0.0));

// Read world-space position
GlobalTransform gt = child.getGlobalTransform();
System.out.println(gt.getTranslation());          // Vector3(15.0, 0.0, 0.0)
System.out.println(gt.getScale());                 // Vector3(1.0, 1.0, 1.0)

// Access the 4x4 matrix directly
Matrix4 mat = gt.getTransformMatrix();
System.out.println(mat.m03);   // 15.0 -- world-space X translation

// Euler angles in degrees
Vector3 angles = gt.getEulerAngles();
System.out.println(Math.toDegrees(angles.x));   // 0.0 (no rotation)

// Using evaluateGlobalTransform to include geometric offset
Matrix4 manualMat = child.evaluateGlobalTransform(true);

Methods

  • GlobalTransform sa vypočíta v čase node.getGlobalTransform() sa pristupuje; je nie aktualizované dynamicky, ak je rodičovského uzla Transform neskoršie zmeny.
  • Getter je getScale() zapnuté GlobalTransform (nie getScaling()). Lokálny Transform používa getScaling() pre zapisovateľnú vlastnosť mierky.
