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.

This forum uses the BBCode (Bulletin Board Code), here are some instructions:

I would like to get 2D screen coordinates of a 3D coordinates point with ninevehgl. How can I do that?

I found code in ogre3d

Vector2 GetScreenspaceCoords(const Vector3& iPoint, const Camera& iCamera)
Vector3 point = iCamera.getProjectionMatrix() * (iCamera.getViewMatrix() * iPoint);

Vector2 screenSpacePoint = Vector2::ZERO;
screenSpacePoint.x = (point.x / 2.f) 0.5f;
screenSpacePoint.y = (point.y / 2.f) 0.5f;

return screenSpacePoint;

Please, help me to write the same code in obj c with ninevehgl

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.
