Re: [osg-users] How to disable culling of a node

Hi Emilio, I think the best way to achieve what you want is to render your scene using two osg::Camera (two pass), first render your scene and then render the object you want to be in the first plane. Each camera have it's own near/far clip planes. Cheers, On Mon, Apr 14, 2008 at 3:06 PM, Emilio

Re: [osg-users] How to disable culling of a node

Hi Joachim, It's true, I can set the clipping plane nearer to me. But then I get z-fighting effects in my scene, due to loss of precision in depth buffer when near plane is close to 0.0 (and far plane has a high value due to the size of my landscape). Kind regards, Emilio. 2008/4/14, Joachim E.

Re: [osg-users] How to disable culling of a node

Hi Emilio, the near clipping plane defines the border between things that are "in front" or "behind" you (resp. the camera). Since you cannot see what is behind you, I should expect that deactivating the clipping will not accomplish what you're looking for. If you want to see more of the ship

Re: [osg-users] How to disable culling of a node

Hi all, Thank you for your responses. I realize that I didn't explain myself very well. What I am looking for is a way to render a first person model in front of my scene (in my case, the bow of a ship). I thought that with Node::setCullingActive() I could accomplish this effect, I mean, to rende

Re: [osg-users] How to disable culling of a node

HI Emilo, You can't switching of OpenGL clipping, you can only move the near and far planes to encompass you model so it doesn't clip it - its the way that graphics pipeline in hardware works. The OSG by default will automatically compute the near and far planes to prevent clipping, but since you

[osg-users] How to disable culling of a node

Hi all, I'`m trying to get a node always drawn without being affected by near clipping plane defined in projection perspective. With the following simple code what I expected to get is that the cow was not clipped by near or far planes, but the cow is still clipped. Could you give me any hints?
