X3DOM in TW6

[zemoxian]

I've been experimenting with X3DOM. I'm able to display 3D graphics in a Tiddler using the X3D tag. However, when a new X3D is inserted into the DOM, x3dom.reload() has to be called for it to display 3D content.

I've created a widget to call it with a button click. I'm wondering if there is a better way to do it?

This sounds neat, so you have a demo somewhere? And for many javascript libraries that you have to reload you can put the function in the code that adds something new so it happens automatically.

I found this link:

http://www.x3dom.org/

One approach is to write a <$x3d> widget that calls x3dom on its child elements after it has executed/refreshed them:

<$x3d width='500px' height='400px'>

    <scene>

        <shape>

            <appearance>

                <material diffuseColor='1 0 0'></material>

            </appearance>

            <box></box>

        </shape>

    </scene>

</$x3d>

That way you can reuse all of TW’s abilities to eg transclude attribute values and the list widget to generate repetitive structures.

Best wishes

Jeremy.

Could you click on a side of a cube and navigate to a tiddler?

I imagine a widget like the $button widget could provide that. I tried <$button tag=shape ...> but it didn't work (only tried it on my iPhone). I think a variation of the button widget could work though. Just need to work out what isn't working.

This works fine. An $x3d widget may be useful but I haven't needed it yet. i need the <<x3dreload>> button to make it visible. The widget could make it unnecessary.

<x3d width="300px" height="300px" >
<scene>
<viewpoint position="3 2 10"></viewpoint>
<$list filter="[tag[Shapes]]"><$transclude /></$list>
</scene>
</x3d>
<<x3dreload>>
