I just wondering if any 3D picture property exists, that show a coordination axis somewhere on 3d picture scene (see the picture pls), or shall i import it as a file and add to 3D picture scene?

Cheers

The latter. Or draw it using primitives. The other issue is how to keep it in the corner while user is rotating the model - I would like to have special billboard mode for this. Now you have to constantly change position of th axes to follow changes of viewport, or to implement your own controller which rotates and translates certain sceneobject (parent of model itself) and only rotates axes.

Sorry for answering so late - I missed this post.

You can find an example here. Nodes descriptions are made in billboard mode.

I posted a VI snippet in one of your other topics answering to another member. It's not as pretty as the one on your image, but it gets the job done. It simply draws 3 lines, one for each axis (X=Red, Y=Green, Z=Blue) with a specified length (in units) and width (in pixels).

You can pin the axis display to the bottom right by using a viewport.

 

See HERE for a very simple example on using viewports to view duplicate copies of a single model.

 

Prohibiting the scales to be panned and scaled by the camera controller is still awkward but at least this way you can limit the draw region of the axis indicator to where you really want it.
