Attached image was achived with iso_csg library. This time isosurface use
function with following syntax:

#local f_V=IC_Intersection2 (
  IC_Threshold( IC_Char("V") , .4 ) ,
  IC_Scale( IC_Threshold( function{pattern{brick}} , .5 ) , .1 )
 );

Threshold around character was used to move surface of letter outside of
shape. Rounded version of iso_csg was used so edges after threshold are
rounded. Threshold around pattern was used to show value of pattern used as
surface. Simple yellow pigment used. Calculated max_gradient was 3999.456 but
884 used.

Any comments ?
