Is there a way to determine what quality setting is being used to render an
image?  I'd like to be able to test it and if it is below 5 replace some
slow rendering Function surfaces with simple objects.

In a related question, I'm using a parametric surface which renderd very
slowly does anyone have any suggestions on how to optimize the process?

No. You could do something very similar by just declaring a variable at 
the beginning of the scene file though.

Write some code to generate a mesh from the parametric equations. The 
mesh will render much faster than the parametric object, but will parse 
much more slowly, and you might have faceting problems if you use too 
low-res of a mesh. There is an include file somewhere called 
parametric.inc that does this.

  On the other hand, you can save the mesh to a file to reuse it later.

Or you duplicate the value in a variable, using the Declare constant
argument (5.2.3.1  Constant).

I have this already, but I keep forgetting to reset it.  I was hoping to be
able to automate the process.  Is there any way to pass information from an
the commandline or .ini file to the file being rendered?

Thanks for the help.

  See the section 5.2.3.1 of the POV-Ray documentation.
