Login Action Required

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 there!

First, thanks for this marvelous 3D engine! I'm following beta versions with real interest (Collada animations is my most wanted feature ^^)

I didn't find a way in the documentation to give a value to a mesh opacity, 50% for example. Is there a way to do that?

Hello buddy,

This is a NGLMaterial related stuff. Mesh is just responsible by the structure and movement.
The appearance is fully responsible of the NGLMaterial.
(http://nineveh.gl/docs/Classes/NGLMaterial.html#//api/name/alpha)

Remember that by default the alpha channel is disabled, if you want to use any alpha component in NinevehGL you must enable it first:
nglGlobalColorFormat(NGLColorFormatRGBA);
nglGlobalFlush();


Also, as a Good Practice, remember that any call to the global API should be made before starting any NGLView.

Ok, thanks for the advice! Now I have another problem, so I will create a new thread for that
