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.

Methods to calculate position via angle and distance

Currently whenever I wish to calculate a new xyz position based on an xyz angle and a distance, I use a "dummy" NGLObject3D and use a combination of lookatpoint and nglmove commands to get the new position (examples of this can be seen in my thread on collision).

I realize I could implement my own methodology using some trig and whatnot, but I think it would be very beneficial to have a built-in set of methods to do this on an NGLObject3D, such as:

(NGLVec3)calculatePositionAtDistance: (float)distance withRotation: (NGLVec3)rotation;
(NGLVec3)calculatePositionByOrbittingObject: (NGLObject3D*)object withRotation: (NGLVec3)rotation atDistance: (float)distance:

Etc. Just a set of methods to help with position calculations for various situations. Ofcourse this isn't extremely urgent or important as we can do this ourselves, but down the road it would be nice to have.

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.
