[X3D-Public] Draggers in X3D?

[Limper, Max]

Yes, this could be a possible interface -although I would prefer to have the dragger potentially separated from the stuff that should be dragged, and just connected via ROUTEs or DOM Events.

Since there are (and will be) no Protos in X3DOM, it could make sense to implement some draggers...

Do you mean something like this:
<Dragger>
... the stuff you want to drag
</Dragger>

If X3Dom defines Sensor nodes, you might be able to hack a non-standard Dragger node in javascript, by combining the Sensor and Transform nodes into a Dragger node.

In general, there may be a hunger for higher-level nodes in X3Dom which are currently left up to Proto developers in desktop web3d.  Perhaps there could be a PROFILE for desktop web3d that's compatible with popular x3dom composite nodes.

Thanks for the examples!
Actually, I meant something more simple, in an ideal case something that does not require any additional JavaScript code, except for catching some event, maybe. For example, I could imagine that you rotate some gizmo, which is represented as a special node, and that node throws an event (or has an output field) which contains the current transform, so you can connect (/ route) that transform to the object you want to rotate.

Regards,
Max

Do you mean something like the Sensor nodes:

PlaneSensor:
