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.

Hi,

I'm having a lot of trouble with lights.

I'm trying to draw an human body. When I draw the skeleton everything is ok, like in the image below.

But when I try to draw the muscle, its looks like strange.

Without nglGlobalLightEffects(NGLLightEffectsON); i get this: https://www.dropbox.com/s/ef2g1lazhcunhxm/IMG_0467.PNG , but its too ugly...

Can anyone help me?

Thanks!

In response to: @fa_palma

Lights in NinevehGL is just experimental. There is only one light (the global light) that you can access via "defaultLight".
http://nineveh.gl/docs/Classes/NGLLight.html#//api/name/defaultLight

If you can't achieve the desired results with the global light the correct way is to implement your own custom shaders to manipulate your own custom lights. Of course dealing with shaders requires more knowledge about OpenGL it self and also about how NGLShaders work.

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.
