GlobalTransform – Aspose.3D FOSS for Java

Notes

GlobalTransform yra tik skaitymui momentinė nuotrauka Node’s pasaulio erdvės transformacija. Ji gaunama per node.getGlobalTransform() ir atspindi mazgo savo Transform su visų protėvių transformacija 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().

Notes

Class	Description
`GlobalTransform`	Read-only world-space transform snapshot. Exposes the composed translation, rotation, scale, and matrix of a node in world space.

Name	Type	Access	Description
`translation`	`Vector3`	Read	Returns the world-space translation (position) of the node.
`rotation`	`Vector3`	Read	Returns the world-space rotation (Euler angles) of the node.
`scale`	`Vector3`	Read	Returns the world-space scale of the node.
`transformMatrix`	`Matrix4`	Read	Returns the full 4x4 world-space transformation matrix.

Signature	Description
`getTranslation()` to `Vector3`	Returns the world-space translation of the node.
`getRotation()` to `Vector3`	Returns the world-space rotation of the node.
`getScale()` to `Vector3`	Returns the world-space scale of the node.
`getTransformMatrix()` to `Matrix4`	Returns the full 4x4 world-space transformation matrix.

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