  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.

Enabling antialias makes camera(QCAR) videobackground black.

I wanna enable antialias for rendering models with QCAR.
But I found that when I turn on antialias, the camera video background becomes black.

I tried to enable antialias globally and locally, both cause the same result.
- Global API


- NGLView

nglView.antialias = NGLAntialias4X;

Any idea?

Hello buddy,

Actually any antialias will work with QCAR, because their OpenGL frame buffer is not allowed to that. The antialias consumes a lot of processing and using it with AR is not advisable at all. Could be much better if you just increase the contentScaleFactor (NGLView) to get better images.

But if you really need the antialias, the best you can do is to completely separate the AR camera from the NinevehGL. NinevehGL will take care of the antialias and the AR Engine will work on a separated EAGLContext without antialias.

This is not an easy task. I suggest you to take a look at the AR engine tutorials to see how you can use their templates and then just place a NGLView above it in a separated view.

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.
