GlobalTransform

GlobalTransform – Aspose.3D FOSS for Java

Notes

GlobalTransform er en kun lesbar øyeblikksbilde av en Node’s verdensromtransformasjon. Den oppnås via node.getGlobalTransform() og reflekterer sammensetningen av nodens egen Transform med hver forelderens transformasjon opp til scenens rot.

Alle egenskaper er kun lesbare. For å endre en nodes posisjon, endre nodeens lokale Transform i stedet.

GlobalTransform instansieres vanligvis ikke direkte; du mottar den fra 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 beregnes på tidspunktet node.getGlobalTransform() er aksessert; den er ikke oppdatert dynamisk hvis en overordnet nodes Transform senere endringer.
Getteren er getScale() på GlobalTransform (ikke getScaling()) Transform bruker getScaling() for den skrivbare skalaegenskapen.
