Using polygonal techniques

OSG supports various polygonal techniques for manipulating the geometry objects. These pre-processing methods, such as polygon reduction and tessellation, are often used to create and improve polygonal models for rendering at a later time. They are designed to have a simple interface and be easy to use, but may perform complex calculations backstage. They are not suggested to be used on-the-fly because of possibly massive computations.

A few polygonal technique implementations in OSG are listed as follows:

1. osgUtil::Simplifier: This reduces the number of triangles in geometries. The public method simplify() can be used to simply enter a geometry object.
2. osgUtil::SmoothingVisitor: This calculates normals for any geometries ...
