[X3D-Public] Prototype

[John Richardson]

Hello,

Is this a loss of usability from the development perspective?

Hi Daniel,

there is the vague hint on http://www.x3dom.org/?page_id=158 to use DOM/HTML techniques, and there is a discussion on the x3dom developer mailing list suggesting to use the component system:

http://sourceforge.net/p/x3dom/mailman/message/30219569/

https://x3dom.readthedocs.org/en/latest/components/index.html#extending-x3dom

This talks about to how to define your own nodes, essentially in parallel to how x3dom.js defines nodes. Unfortunately, the example is a bit too basic and one would need to look at x3dom source to understand better how to do that. See for example https://github.com/x3dom/x3dom/blob/master/src/nodes/Geometry3D/Box.js .

Another basic idea is to create and manipulate nodes procedurally, not declaratively. The scene API helps with that:
http://doc.x3dom.org/author/index.html. So one could image a javascript function which inserts a series of nodes into the DOM based on provided parameters. This approach may be more accessible and there some basic examples on http://examples.x3dom.org/simpleExamples.html which provide pointers in that direction.

Hope this helps,

Andreas
