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.

Set GlBlend function for specific materials

Hi guys,

I try to find a way to render some materials with "multiply blend mode" (on top of the camera preview).

Is there a way to define glBlend functions for specific materials (ZERO, SOURCE_COLOR).

Thanks

Hi,

No, there is no options for blending pixel modes yet. Actually, probably it will not exist in the future as well, because NinevehGL takes the same concepts of 3D modeling softwares, not from OpenGL it self.

So in the future you'll be able to change the blends via material, but not directly like OpenGL does.

Ok, I'd finally separate models in different meshes/cameras then manually change glBlend functions:



glEnable(GL_BLEND);

glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
[_cameraA drawCamera];

glBlendFunc(GL_ZERO, GL_SRC_COLOR);
[_cameraB drawCamera];

glDisable(GL_BLEND);


thx

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.
