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.

In iOS 6.0.1 if antialiasing is turn on the drawToImage method doesn't grab a screenshot of the view. To reproduce the bug just try the OffScreen demo and add the following code on viewDidLoad:

NSDictionary *settings = [NSDictionary dictionaryWithObjectsAndKeys:
kNGLMeshOriginalYes, kNGLMeshKeyOriginal,
kNGLMeshCentralizeYes, kNGLMeshKeyCentralize,
@"0.5", kNGLMeshKeyNormalize, nil];
nglGlobalAntialias(NGLAntialias4X);
nglGlobalFlush();
_mesh = [[NGLMesh alloc] initWithFile:@"barrel.obj" settings:settings delegate:nil];


Any idea on how to fix this?

Thanks

Yeah, the next NinevehGL version is taking too long to be released. All the bugs related to iOS 6 will be solved soon.

I know that you are working on the new version but is there any quick fix for this problem by setting some properties on the EAGLView?

Cheers

Nope. I fixed a problem related to the MVP that was wrongly computed and I need it to transform the 3D coordinate on 2D coordinate of the viewport. Waited a little longer for a fix for this drawToImage issue but my client couldn't wait any more. So I disabled the antialiasing to submit the new version of Magicspace to the App Store.

Hi;

I have the same issue. I also disabled antialiasing but still I cannot grab a snapshot of the mesh. How did you solve 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.
