- (v4.0) add visible field to X3DBoundedObject, Mantis 1271<br>
<a href="https://www.web3d.org/member-only/mantis/view.php?id=1271" rel="noreferrer" target="_blank">https://www.web3d.org/member-only/mantis/view.php?id=1271</a> (no longer named 'hidden')<br>
<br>
Preceding mail threads, summarized in Mantis:<br>
<br>
* As node list kept getting longer, realized X3DVisibleObject same as X3DBoundedObject.<br>
<a href="http://web3d.org/pipermail/x3d-public_web3d.org/2020-January/011673.html" rel="noreferrer" target="_blank">http://web3d.org/pipermail/x3d-public_web3d.org/2020-January/011673.html</a><br>
<br>
* Confirmed by Andreas as implemented in InstantReality: refactor visible field as part of X3DBoundedObject, 37 nodes total.<br>
* <a href="http://web3d.org/pipermail/x3d-public_web3d.org/2020-January/011674.html" rel="noreferrer" target="_blank">http://web3d.org/pipermail/x3d-public_web3d.org/2020-January/011674.html</a><br>
<br>
Test scene available:<br>
* X3D Example Archives: X3D for Advanced Modeling, Animation, Visible Shapes Test<br>
"Test scene for visible field on X3DBoundedObject nodes, which is new to X3Dv4."<br>

<br>
New refinement:<br>
- (v3.2+) CollisionCollection implements X3DChildNode, not X3DNode<br>
- (v4.0) CollisionCollection contains nodes with X3DBoundedObject interfaces, so<br>
TODO CollisionCollection needs to be marked in specification as X3DBoundedObject as well.<br>
now recorded as issue 1275<br>
