Hi all.
In setting up some billiard balls in a triangle formation, I discovered that
I needed to make the z co-ordinate the square root of 3.
I have been using < 0, 0, 1.713> which is fine, but I was wondering if there
is anyway of doing it like < 0, 0, SQRT(3) > or some such.
Thanks

<0,0,pow(3,1/3)>

'Scuse me? That would be cube root not square root. Try pow(3,1/2).

Yes, bit tired and misread the 3 part as wanting the cube root.
RareBeast: Just so you know, the pow() function is used for all powers and
roots (including cube roots...), the '^' operator having been removed a few
versions ago.

where is the problem ?
sqrt() is a povray function. read

Be careful! The inputfiles are parsed case sensitive. So just try
sqrt(3) and everything will be alright ;)
So far,
