No there isn't. But there are macros in shapes.inc for making rounded 
versions of some common shapes...boxes, cylinders, cones.

    There are many separate features that combine for this. The first 
thing you mention seems to be about surface imperfections...a flat 
surface in POV appears perfectly flat, unlike most real-world surfaces. 
You can use the normal feature to make them appear uneven or bumpy.

    Also, you need to use realistic lighting. Don't be afraid of using 
light values greater than 1. Try designing your scene with an ambient of 
0 for all non-glowing objects. The easiest way to do this is to put 
"#default {finish {ambient 0 diffuse 1}}" at the beginning of your 
scene. This improves contrast and the 3D look of your scene. A fill 
light at the camera location can still provide illumination into 
shadows, without the flatness of ambient lighting. Try radiosity as 
well...radiosity simulates indirect lighting by light diffusely 
reflecting off of nearby objects, like the glow from a sunlit spot in a 
dark room. If you have highly reflective or transparent objects, photon 
mapping can be a good idea. Photon mapping simulates specular 
(mirror-like) reflective and refractive caustics, like light shining 
through a colored glass. This can make a scene appear much more 
realistic with little effort.

    Other things depend on your scene. An outdoor scene with far objects 
will often show atmospheric haze. The fog feature is usually best for 
this. For dense fog, scattering media may be better, as it will show 
light beams and shadows that pass through it. As for the sharpness, 
there is a focal blur feature.
