包路径：com.jme3.scene.Spatial
类名称：Spatial
方法名：updateGeometricState

Spatial.updateGeometricState介绍

[英]updateGeometricState updates the lightlist, computes the world transforms, and computes the world bounds for this Spatial. Calling this when the Spatial is attached to a node will cause undefined results. User code should only call this method on Spatials having no parent.
[中]updateGeometricState更新光照列表，计算世界变换，并计算此空间的世界边界。当空间连接到节点时调用此函数将导致未定义的结果。用户代码应该只在没有父对象的空间上调用此方法。

private void fixRefreshFlags(){
  // force transforms to update below this node
  spatial.updateGeometricState();
  
  // force world bound to update
  Spatial rootNode = spatial;
  while (rootNode.getParent() != null){
    rootNode = rootNode.getParent();
  }
  rootNode.getWorldBound();
