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.

Hello,

I want to use NinevehGL in an Augmented Reality App I'm going to write with vuforia. I think NinevehGL is really awesome in connection with vuforia because of the easy loading and rendering of 3d models in particular.
Another thing I want to do in my app is playing Videos on 3d planes just like in the vuforia VideoPlayback sample and I want to know whether this is possible in connection with NinevehGL.

Basically this part of the FAQs got me thinking:
Can I use third party libs with NinevehGL? Like an Augmented Reality lib?

A: Yes, but it depends on what kind of information your third party lib needs. For example, if the lib needs only matrices or spacial location it's OK, you can pass those informations by calling a method on your NGLMesh instance. However, if your third party lib needs something deep in OpenGL pipeline, like framebuffers, then you can't use this lib with NinevehGL, because all the OpenGL structure is under the surface in NinevehGL.


From looking at the vuforia samples my basic understanding is, that I need to convert the video frame-by-frame to an OpenGL Texture and upload it on a 3D plane. Can this be done in connection with NinevehGL ? I'm wondering since there is no renderFrameQCAR method like in vuforia...

Regards

In response to: @alexhaberschlac

Hi,

Yes, you can. There is one AR example inside the NinevehGL that includes Vuforia SDK.

About the video stuff, I'm not sure if it'll achieve the performance you want. To achieve such thing, there are a lot of pre-rendered routines that you should do to optimize the video conversion into OpenGL textures and NinevehGL pretends to take care of the texture process for you, however it is not prepared yet to do such thing.

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.
