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.

Copying and scaling meshes

I have a scene that is composed of a set of spheres of different sizes.

Can I render this scene by importing a single sphere from a file and copying, translating and scaling it in the final scene?

Sure, use the copy or copyInstance methods of your NGLMesh. You don't need to wait until the mesh loading is completed, you can copy it right after initialize the loading.

Hey there! Great engine!

In respect with copyinstance, I am using it to draw during 'drawView' and it seems to slowdown the performance of the app (Visually a small lag when copyinstace is called)

Briefly what I am doing is, I moving camera on -z axis at a particular speed, and adding mesh(by using copyinstance) about 100 distance away, and removing the mesh (using camera removeMesh) thats behind the camera.

Can you let me know, if there is a way to fix the lag? the mesh has about 1000 vertices. Thanks

I can say without a deep investigation. There are hundreds of other things that can led you into that.

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.
