Hi all,

Maybe it is kind of silly question, but as far as I am new to PovRay I can't
deal with it. The thing is I don't understand how the list of values (followed
by points) in the spline declaration works. For linear_spline these values
doesn't matter what is quite obvious. But for quadratic_ or natural_spline they
matters. It is written in documentation they are some parameters, but nothing
more. Where will I find some helpful informationa about spline declarations?
Because otherwise I don't know what I do. Thanks in advance.
Best regards,
Twister
