Textures must be declared before the macro call, but you can
change that if you wnat to.
The paramaters VVertical and HHorizontal refer to the amount
of pov units you want to fill, so if you use
object{Laticework(10,10,0.5,T_Wood31)}
the finished product will cover an area <-5,-5,-0.25>,
<5,5,0.25>. obviously you can translate and rotate after
calling.
The version that uses cylinders instead of a box for the
center piece is CylLatice which is also icluded
below.
Enjoy
