I saw a mistake of mine, the rows of arrays p,q are from 0 to 29, and for qq
0 to 18, so I changed thses numbers in #while loops as 30 for planes and 19
for quadratics, but still I couldn't see any image after even 5 minutes, is
this normal in Povray?

It is written

Parsed ..... tokens


and number of tokens is changing and very big numbers,

what does this mean?

why I can not see the image?

what can I do to see my image?
