sceneUpdated（）vs invalidate（）

Question

viewer.impl.sceneUpdated()和viewer.impl.invalidate()有什么区别？我已经看到它们一直在互换使用，但无法弄清原因。

在invalidate()的情况下，我已经看到它使用每个可能的组合接受1到3个布尔参数，并且每次看起来都给出相同的结果。

Answer 1

viewer.impl.invalidate基本上是：

invalidate(needsClear, needsRender, overlayDirty)
//needsClear - full render - not (currently) interruptible, runs until completion, "locks" application, needs to re-render the whole scene from start
//needRender - progressive render - show a bit more each tick, runs unless interrupted by a move, control, etc.
//overlayDirty - overlay (like rollover highlighting etc) needs to be re-rendered

[sceneUpdated(objectsMoved, skipRepaint)基本上是

this.invalidate(!skipRepaint, false, !skipRepaint);

加上场景边界将被标记为要更新，并且阴影将被重新渲染。
