GlobalTransform

GlobalTransform

Methods

GlobalTransform yra tik skaitymui momentinis vaizdas Nodepasaulio erdvės transformacija. Ji gaunama per node.getGlobalTransform() ir atspindi mazgo savo Transform su visų tėvų transformacijomis iki scenos šaknies.

Visos savybės yra tik skaitymui. Norėdami pakeisti mazgo padėtį, modifikuokite mazgo vietinį Transform vietoj to.

GlobalTransform paprastai nėra sukuriamas tiesiogiai; gaunate jį iš node.getGlobalTransform().

Methods

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 apskaičiuojama tuo metu node.getGlobalTransform() yra pasiekiama; tai yra ne atnaujinama dinamiškai, jei tėvo mazgo Transform vėlesnių pakeitimų.
  • Getteris yra getScale() ant GlobalTransform (ne getScaling()). Vietinis Transform naudoja getScaling() rašomam mastelio savybei.
