Hi Julio, The OSG by default clamps the near/far planes to the extents of your model. You can disable this via:
viewer.getCamera()->setComputeNearFarMode(osg::CullSettings::DO_NOT_COMPUTE_NEAR_FAR); This has nothing to do with culling though, you seem to confuse near/far planes and culling in your post. The methods you mention have nothing to do with the OSG itself too, I can only presume you are writing psuedo code or have other funcitons that only your code has, but are not in the OSG... which kinda makes it hard to other to really understand what you are doing. It may be best to simply buy one of the OSG books and work through it, it'll help your tremendously with understanding how things all work. Robert.
