// e.g. the root node has intensity range [1, 478]. One of the descendants increases range to
// [0, 2047]. We should not automatically change to the new range because that would result
// in sudden and drastic changes of brightness. We should adjust the min/max of the sidebar slider.

关于透明度：
由于点云和mesh是分开渲染的，且材质很不一样，所以透明和blend有冲突
1 如果点云的blend是AdditiveBlending，也就是普通的叠加模式。
则半透明点云的depthTest和depthWrite都为false
这时候mesh要后渲染，且depthWrite不能为false（除非depthTest也为false），否则将被点云遮住。
2 如果点云的blend是普通型
则半透明点云的depthTest和depthWrite都为true。（为何depthWrite不能像mesh一样为false, 否则点云自身透明会错乱，可能因为太多points了）
这时候若mesh全部先渲染，则 透过depthWrite为false的半透明mesh看不透明点云，mesh会完全被点云遮住。但是透明的物体就是depthWrite要为false，否则也会完全遮住点云
即使是后渲染半透明的mesh，若透过点云看mesh，mesh会完全被点云遮住（为什么之前遇到过 透过点云看mesh，点云会显示不出）
最终选择是先渲染不透明的mesh，然后点云，然后透明的mesh。虽然点云对mesh透明会失效。
