GlobalTransform

GlobalTransform — Aspose.3D FOSS for Java

Notes

GlobalTransform je samo za čitanje snimka Node’s world-space transformation. Dobiva se putem node.getGlobalTransform() i odražava sastav vlastitog čvora Transform s transformacijom svakog pretka do korijena scene.

Sva svojstva su samo za čitanje. Za promjenu položaja čvora, izmijenite lokalni Transform umjesto.

import com.aspose.threed.GlobalTransform;

GlobalTransform obično se ne instancira izravno; dobivate ga iz node.getGlobalTransform().

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);

Notes

GlobalTransform se izračunava u trenutku node.getGlobalTransform() se pristupa; to je ne dinamički ažurirano ako je roditeljski čvor Transform kasnije promjene.
Getter je getScale() na GlobalTransform (ne getScaling()). Lokalni Transform koristi getScaling() za writable scale property.
