anyone know how to rotate text using the
 text{ ttf "fontname.ttf" 1,0
rotate <??,??,??> or rotate x*?? }

making it rotate the letters and not rotating it around in a cirlce around
the screen?

i want my text to stay in the same spot just rotate around so i can see the
text.

thanx,
mike

  Rotations always happen around the origin.

  If you want to rotate an object around a certain given point P, first
translate the object so that P becomes the origin, then rotate, then
translate the object back.
  That is: translate -P rotate whatever translate P

  If you don't know P (how could POV-Ray know if even you don't?), then
try searching a good point by eg. putting a cylinder as the axis around
which you want to rotate the object and move that cylinder around until
you find the right spot. The location of the cylinder will then be your P.

BTW origin = <0,0,0>

But if you want to rotate the object and keep it in the same place, then
a good choice for P would be the centre of the bounding box that
contains the text, which you can obtain like this:-

#declare P = (min_extent(TextObject) + max_extent(TextObject)) / 2;
