GlobalTransform

Methods

GlobalTransform ir tikai lasāms momentuzņēmums no Node’s pasaules telpas transformācija. Tā tiek iegūta caur 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.

import com.aspose.threed.GlobalTransform;

GlobalTransform parasti netiek tieši izveidots; jūs to saņemat no node.getGlobalTransform().

Methods

NameTypeAccessDescription
translationVector3ReadGets the translation.
scaleVector3ReadGets the scale.
eulerAnglesVector3ReadGets the rotation represented in Euler angles, measured in degree.
rotationQuaternionReadGets the rotation represented in quaternion.
transformMatrixMatrix4ReadGets the transform matrix.
SignatureDescription
GlobalTransform()Initializes a new instance of the GlobalTransform class.
GlobalTransform(matrix: Matrix4)Initializes a new instance of the GlobalTransform class with the specified matrix.
getTranslation() → Vector3Gets the translation.
getScale() → Vector3Gets the scale.
getEulerAngles() → Vector3Gets the rotation represented in Euler angles, measured in degree.
getRotation() → QuaternionGets the rotation represented in quaternion.
getTransformMatrix() → Matrix4Gets the transform matrix.

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 tiek aprēķināts tajā brīdī node.getGlobalTransform() tiek piekļūts; tas ir nav atjaunināts dinamiskā veidā, ja vecāka mezgla Transform vēlākas izmaiņas.
  • Getter ir getScale() uz GlobalTransform (ne getScaling()) Transform Vietējais getScaling() rakstāmai mēroga īpašībai.
