  I need some help about hidden faces, have anybody an algorithm to
determine it, Also need one to set the order in that I put triasngles in
screen (First deeper then neatest).
  So I usually can't read this group, Please EMail directly to me replies.
  Thanx.

1. help with algorithm for half-toning (ordered dither)

Hi group, I need an algorithm to use a threshold matrix 6X6 and map it over
a 630X422 pixels.
the values in the larger matrix can be between 0 and 255 and the values in
6X6 matrix can be 1 to 18.

the basic structure of an ordered dither is

if g(x,y) < s(x,y)
  G(x,y) = 255 (on)
else
  G(x,y) = 0 (off)

where G(x,y) is the output value, g(x,y) is the input value and s(x,y) is
the threshold matrix.

Any help in this area would be appreciated.
