I've looked but cannot find the answer. :-)

How can I convert a text string in the form of "<x,y,z>" to a vector 
that I can use as a camera position?

#include "strings.inc"
#declare MyString = "<3.3, 6, 2>";
#declare MyVector = Parse_String(MyString);

Alternatively you could write the string to a temporary file (using the 
#fopen, #write and #fclose directives) and include it, but as a matter 
of fact that's exactly what Parse_String does.

Thanks, my brain is dead.

I had problems with <0,0,0> at first.

Now other problems to work out.
