GlobalTransform

GlobalTransform – Aspose.3D FOSS for Java

Notes

GlobalTransform es un solo lectura instantánea de un Node’s transformación en el espacio mundial. Se obtiene mediante node.getGlobalTransform() y refleja la composición del propio nodo Transform con la transformación de cada ancestro hasta la raíz de la escena.

Todas las propiedades son de solo lectura. Para cambiar la posición de un nodo, modifica la local del nodo Transform en su lugar.

import com.aspose.threed.GlobalTransform;

GlobalTransform no se instancia normalmente de forma directa; lo recibes de 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 se calcula en el momento node.getGlobalTransform() se accede; es no actualizado dinámicamente si el nodo padre Transform cambios posteriores.
El getter es getScale() en GlobalTransform (no getScaling()). El local Transform utiliza getScaling() para la writable scale property.
