You can use them in any openglwebgl application with minor changes only shader inputs.

These extensions allow applications to draw large numbers of objects with only a few setup calls, rather than a few calls per object, thus reducing the driver overhead necessary to render highly populated scenery. A surface might be configured to use nbuffers, but is usually doublebuffered or triplebuffered. Generally speaking, a normal vector represents the direction pointing directly out from a surface, meaning it is orthogonal at 90 degree angles to any vector which is coplanar with in the case of a flat surface or tangent to in the case of a nonflat surface the surface at a given point.
