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:

1. 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.
2. 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?
3. 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?

I am looking forward to your reply.

Best regards,
Witold Kosowski
