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 need some help on the following situation:

In the loaded heart 3D object (Heart.obj), I just need to mark points randomly on it (refer screenshot 1) . After marking the points I need to draw a mesh connecting these marked points/change its texture or color so as to differentiate the section/portion from other parts (refer screenshot 2).

Also, is it possible to display only this cropped like section on to a new view as if like an object (refer screenshot 3).

So,can you suggest some efficient methods to achieve it.

Thanks.

In response to: @shamsutk87

About showing the section I suggest you to use UIKit features, like UIView bounds or even the layer mask.

About painting the 3D mesh with a custom section, I'm afraid there is no way to achieve that with the current version. You can't retrieve the UV coordinates from a point in the screen.
