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 was wondering if it is possible to get all the meshes from NGLGroup3D.. It has NGLArray _collection as a private variable, and does not provide any function to get a all the meshes..

It is possible to give a tag to every mesh and use that tag to get the meshes from the Group.. But I was wondering if there is any other workaround. Or more precisely, is there a specific reason for not providing access to all these meshes?

Hello buddy,

Easier than that... NGLGroup3D already is a collection!
Notice that it implements two protocol NGLIterator and NSFastEnumeration.
http://nineveh.gl/docs/Classes/NGLGroup3D.html
http://nineveh.gl/docs/Protocols/NGLIterator.html

Both protocols can be used to loop through all the objects.
Besides, the NGLGroup3D it self has all the methods similar to a collection:

  • add
  • has
  • remove
  • count


Besides you also has methods that can be used to retrieve a specific mesh very fast:

  • objectWithTag:
  • objectWithName:


So, I don't understand what you're looking for. Of course you'll not have direct access to the internal organization system, just as you also don't have access to the NSArray or NSDictionary internal system.
