updateWorldMatrix method

void updateWorldMatrix(bool updateParents, bool updateChildren)

updateParents - recursively updates global transform of ancestors.

updateChildren - recursively updates global transform of descendants.

Updates the global transform of the object.

Implementation

void updateWorldMatrix(bool updateParents, bool updateChildren) {
  final parent = this.parent;

  if (updateParents == true && parent != null) {
    parent.updateWorldMatrix(true, false);
  }

  if (matrixAutoUpdate) updateMatrix();

  if (this.parent == null) {
    matrixWorld.setFrom(matrix);
  } else {
    matrixWorld.multiply2(this.parent!.matrixWorld, matrix);
  }

  // update children

  if (updateChildren == true) {
    final children = this.children;

    for (int i = 0, l = children.length; i < l; i++) {
      children[i].updateWorldMatrix(false, true);
    }
  }
}
