GlobalTransform

GlobalTransform – Aspose.3D FOSS for Java

Notes

GlobalTransform ir tikai lasāms momentuzņēmums no Node’s pasaules telpas transformācija. To tiek iegūts, izmantojot node.getGlobalTransform() un atspoguļo mezgla paša Transform ar katra priekšgājēja transformāciju līdz ainas saknei.

Visas īpašības ir tikai lasāmas. Lai mainītu mezgla pozīciju, modificējiet mezgla lokālo Transform tā vietā.

GlobalTransform parasti netiek tieši instanceizēts; jūs to saņemat no 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 tiek aprēķināts brīdī node.getGlobalTransform() tiek piekļūts; tas ir ne atjaunināts dinamiskā veidā, ja vecāka mezgla Transform vēlākas izmaiņas.
Getter ir getScale() uz GlobalTransform (ne getScaling()). Vietējais Transform izmanto getScaling() rakstāmas mēroga īpašībai.
