I'm not sure what you mean by a 'punched' surface. The only thing I can  
think of is with my first coding which used boxes if you had three boxes  
height 0,3 and 0 it would be like standing next to a skyscraper. The  
second code using the bicubic patch should solve that by smoothing the  
points together, did you try that one though you have to watch it uses all  
the data.

For proper smoothness the height_field solution from Mike is probably  
going to be the best option for you.

I've been constantly impressed by everyone here ever since I started using  
povray.

I wouldn't really have noticed if you hadn't mentioned it, you write and  
construct better English than some native speakers.
