本文整理了Java中com.jme3.scene.Mesh.updateBound()方法的一些代码示例，展示了Mesh.updateBound()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Mesh.updateBound()方法的具体详情如下：
包路径：com.jme3.scene.Mesh
类名称：Mesh
方法名：updateBound

Mesh.updateBound介绍

[英]Updates the bounding volume of this mesh. The method does nothing if the mesh has no Type#Position buffer. It is expected that the position buffer is a float buffer with 3 components.
[中]更新此网格的边界体积。如果网格没有类型#位置缓冲区，则该方法不会执行任何操作。预计位置缓冲器是一个由3个部件组成的浮动缓冲器。
