Recalculate bounding box

[danilokrulj]

Hi, has anyone had the need to recalculate objects bounding box at some point? I show/hide parts of the model which changes the models height, but the dimension hotspot guides stay the same. I would like to recalculate the bounding box and redraw the dimension lines when the changes happen.

I guess I could change the values of the hotspots manually for this case but I was wondering is there a better / faster way to do this?

First off, very nice use of MV's advanced features! Please feel free to share your site on our show & tell or on twitter and @modelviewer.

The bounding box gets recalcuated by updateFraming(), but I'm not sure you also want to reframe the camera.

Thank you elalish.

Would the bounding box recalculation work if I just set the meshes visibility to false (I feel like it would still be included in the bounding box since its just not visible but its still there)?

I made my case work manually by changing the values for the hotspots on button click but I'm asking for future reference :)

mesh visibility isn't part of our public API (yet), so I wouldn't bank on it. By that I mean, we can only hide something by making it transparent, which I'm not sure if that should really change the bounds...
