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.

Panorama Sample Better Quality

I was wondering if there´s a way to improve quality of images loaded as texture on the Panorama Sample. I´m using images of 10669x3126 and even so the quality of results looks very poor on an iPad 2. I would be grateful if someone could give me a solution.

Globals:
  nglGlobalColor(nglColorMake(0, 0, 0, 1));
nglGlobalColorFormat(NGLColorFormatRGBA);
nglGlobalLightEffects(NGLLightEffectsOFF);
nglGlobalTextureQuality(NGLTextureQualityTrilinear);
nglGlobalAntialias(NGLAntialias4X);
nglGlobalTextureOptimize(NGLTextureOptimizeNone);
nglGlobalFrontAndCullFace(NGLFrontFaceCW, NGLCullFaceBack);
nglGlobalFlush();

Yeah,
This is a limitation of OpenGL. The maximum size for a single texture is 2048, even for retina displays. As the whole panorama has one single texture file, that means the 360º have 2048 pixels.

You can change the original .OBJ and edit it to receive more than one single texture, like 2 or 4. Then change your code to load 2 or 4 textures and place them in the right place.

Of course you must cut and crop your panorama image in 2 or 4 as well.
