x_ite just follows standard SAI, internal or external:<br>
<br>
//get Browser<br>
browser=X3D.getBrowser(); //X3D is global defined by x_ite.js<br>
//get current scene<br>
scene=browser.currentScene;<br>
//make shape node<br>
shape=scene.createNode('Shape');<br>
//make box node<br>
box=scene.createNode('Box');<br>
//set geometry field<br>
shape.geometry=box;<br>
//add as root node (for example)<br>
scene.addRootNode(shape);<br>
<br>
For me the easiest way to experiment with scripting like this, is to<br>
use the Chrome dev tools console with a simple scene like:<br>
<a href="https://www.web3d.org/x3d/content/examples/Basic/UniversalMediaPanoramas/desert3X_ITE.html" rel="noreferrer" target="_blank">https://www.web3d.org/x3d/content/examples/Basic/UniversalMediaPanoramas/desert3X_ITE.html</a><br>
Following the steps will give you a white box visible in the active scene.<br>
<br>
x3dom uses the DOM as an interface to the scene. So you create DOM<br>
elements using HTML5 methods and add those to the Scene DOM element.<br>
There may be a way to avoid using the DOM and use internal, SAI like<br>
functions. For example, the javascript domNode._x3dom property gives<br>
you access to fields and methods for a node. But usually it is easiest<br>
and most interoperable on a HTML5 page to use the DOM.<br>
<br>
The field names are the same across browser but the internal<br>
representation of field values (as a javascript object) is very<br>
different. So one cannot use the results of SAI x_ite calls directly<br>
with x3dom, or vice versa. It is necesssary to go through encodings.<br>
<br>
I do not think X3DJSAIL deals a lot with Browser or ExecutionContext<br>
SAI functions since they are tied to the specific browser but I may be<br>
wrong.<br>
