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.

Hey, is it possible to create a 3D Globe which is interactive, as in we come to know where exactly on the model we have touched, so that we can map the touch point to the actual Globe and then retrieve its latitude and longitude..

Thanks in advance

Hello buddy, unfortunately NinevehGL doesn't have a full touch API yet. The next version will bring it.

I would very much like a function that calculate the camera ray that projects through the view point coordinate in the NGLView. This seems like a very useful primitive for translating touch into rays that we can do scene intersection tests with. I'm a bit rusty on OpenGL view space and projection matrix math. I'll follow-up with code if I crack it tonight.

The next version of NinevehGL will bring much more than rays, there will be 3 ways to identify collisions and touches, each one with its own cost and performance.

For now, a good choice is a kind of plugin to NinevehGL, developed by one of your users:

Hope it helps.
