Dear All,

I always encounted with the problem of Bbox, whatever the scenes I loaded.

Here’s the error :
[WARNING] [RealGUI] Global Bounding Box seems very small; Your viewer settings (based on the bbox) are likely invalid, switching to default value of [-1,-1,-1,1,1,1].This is caused by using component which does not implement properly the updateBBox function.You can remove this warning by manually forcing a value in the parameter bbox="minX minY minZ maxX maxY maxZ" in your root node

I followed the tips on this post. However, the problem is still existing.

My questions are :
– how to choose the values of minX minY minZ maxX maxY maxZ ?? could they can be calculated automatically ?
– how to enable the bounding functions in XML files ??

——————-
Everything seems so complex in SOFA without a clear tutorial (different versions will also give different results….)!

Anybody can help me ? Thanks a lot!

Best regards,
Fei

Hi Fei

You should read carefully the error messages.
It explains that you can set the bbox="-1 -1 -1 1 1 1" in the root node to specify the bounding box. Bounding box is usually computed by visual model (OglModel), in this case the bbox is automatically computed. I guess you do not have an OglModel in your scene. That’s why you have this warning.

Let me know if this fixes your issue.
Best

Hi Hugo,

Actually, I didn’t set any bounding box. I just followed the tutorial in :

https://www.sofa-framework.org/wp-content/uploads/2016/08/2-Tutorial.pdf

These tutorials are not working at all. Nothing is shown in the Software.

It’s the same errors no matter which tutorial I launched in this link :

Thanks!

Best regards,

Hi all,

I rebuilt the newest master branch (date : Oct. 8, 2018) with the source code in this link :
https://github.com/SofaDefrost/sofa

The errors are disappeared. Thus the stable version of v18.06 may still have some unexpected errors (in particular regarding different PCs).

I am really confused about these.

Best regards,
Fei

Don’t be confused.
I close the topic then.

If you face the issue again, please just follow my instructions above, by specifying a bbox value to your root node.

I’m having the same problem with many of the examples. Where do I specify the root bounding box in the properties of the root dialog
