> Hi, 
>

> I would like to implement a 3D viewer in our FABulous project and I have decided on the 3D-UI-XML3D GE. There are couple of questions I would need anserwed in order to implement the GE with the possibly best results fot the project:  
>
>   * Is it possible to get a detailed specification of the xml3d-json format? Since I couldn't find any converter capable of creating the xml3d-json directly from an stl file, I'm going to have to create it myself based on the data read from the stl. I'm getting a mesh object with lists of vertices, normals, texture coords and more, but I need to know the exact specification so that I am certain that the created json will be correct. 
>   * I have downloaded a sample json (teapot.json) from the github page and used it to visualize the object and it is fine, however, after including camera.js the zoom in / zoom out is handeled with RMB+drag combination. Is it possible to change it to a mouse wheel scroll? I think it would be much more intuitive this way. Can the camera.js be initialized in a way to achieve the mouse wheel scroll zooming? 
>   * Lastly, I have created a simple cube json and it is correctly visualized, however when I try to rotate the object it doesn't seem to rotate in a right way - it looks like the object is both rotating and at the same time orbiting and then it sometimes hides out of the canvas bounds. Is the rotation being made always around a certain point, for example (0,0,0)? And I am having trouble in centering the viewed object on the canvas. Setting the view position in the xml does the trick, but I need to set the position automatically so that each uploaded model would appear in the center of the canvas. How can this be done?
