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.

Touch on specific mesh

Hi , I am trying to tap on specific mesh with UITouch , but the problem is NGLmesh is not inherited from UIView so the compiler gives me this warning :

Comparison of distinct pointer types ('UIView *' and 'NGLMesh *')

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

UITouch *touch = [[event allTouches]anyObject];

if ([touch view] == _mesh)



what is your suggestion ?

Hello there,

maybe these threads can help


The method you are using for touching do are just for recognition. I think it is necessary use some sort of collision testing to find out whether a mesh has been touches or not.
So starting from the finger tip, create an own mesh that moves down the z axis and tests whether it collides with another mesh or not.

There is no Touch API in NinevehGL yet, the next version (0.9.4) will bring it.

NinevehGL is a 3D engine built right on top of OpenGL ES and it uses all the programmable pipeline power, making it easy for you to create great application with shaders.
