Login Action Required

The NinevehGL Forum uses a new concept of "socialized forum" or as we like to say "Tweet Forum".


Here is the deal:
  1. No new registration is required. Just sign in with your Twitter account and authorize the NinevehGL Forum.
  2. Once you’re in, you'll be able to "Follow a Thread", that means every time that thread receive a new post or update you'll receive a mention on your twitter.
  3. Besides, you can enable "Auto Share", then every new post and/or thread you make will be tweeted on your timeline. (By default, auto-share is enabled only for your threads)

Forum Rules:

1. We understand human comunication can become "hot" sometimes. So some insults and bad words ARE allowed. Just don't push too much being an asshole all the time.

2. SPAMMERS are not allowed. There are penalties for this kind of user and they can be banned forever.

3. You can report other users, if you judge necessary. An user reported many times by many people can also be banned forever. However you can also receive penalties for report deliberately for no apparent reason.

If there is a similar thread title, make sure the other one doesn't already have the answer you're looking for.

I tried to get the boundingbox of a mesh, and draw a ball that contains the mesh

center.x=(_mesh.boundingBox.aligned.max.x-_mesh.boundingBox.aligned.min.x)/2;
center.y=(_mesh.boundingBox.aligned.max.y-_mesh.boundingBox.aligned.min.y)/2;
center.z=(_mesh.boundingBox.aligned.max.z-_mesh.boundingBox.aligned.min.z)/2;
radius=sqrtf((_mesh.boundingBox.aligned.max.x-center.x)*(_mesh.boundingBox.aligned.max.x- center.x) (_mesh.boundingBox.aligned.max.y-center.y)*(_mesh.boundingBox.aligned.max.y-center.y) (_mesh.boundingBox.aligned.max.z-center.z)*(_mesh.boundingBox.aligned.max.z-center.z));

but the boundingbox seems always returns zero

It seems that _mesh.boundingBox doesn't get initialized at all

You must wait for the mesh be loaded.
Remember that by default, NinevehGL runs all asynchronously. So set the mesh delegate to know when the mesh is loaded. Once it's loaded, the bounding box will be available.

Thanks a lot.
This is really a great engine.
It would be better if the documentation is more detailed.
Anyway thank you!
