SunPHIGS problem

[Amir J. Katz Xpert]

 I  am  a new user of SunPhigs 1.3. While trying to create a new Phigs  program
  I encountered the following problem :

  When I create elements inside the Phigs structure, using my modeling 
   coordinates space, if the modeling coordinates size is larger 
   than ~100, then the element is not displayed on the window.
 
  When I use small coordinates as the modeling coordinates , 
   then the display is o.k.
  Notice that in all the Phigs examples and tutorials, small coordinate
   values are used. (between -2 and ~15)
  It seems as if something is wrong with the translation from
   the modeling coordinates (MC) to the world coordinates (WC).

  Example :
   The coordinates in file pickit.c 
     ( in phigs1.3/examples directory) are :

       static Ppoint3      square[] = { 0.0,0.0,0.0,
                                        0.2,0.0,0.0,
                                        0.2,0.2,0.0,
                                        0.0,0.2,0.0,
                                        0.0,0.0,0.0
                                    };

  I changed them to be :

       static Ppoint3      square[] = { 0.0,0.0,0.0,
                                        200.0,0.0,0.0,
                                        200.0,200.0,0.0,
                                        0.0,200.0,0.0,
                                        0.0,0.0,0.0
                                    };
  and with those new coordinates , the pickit program does not work -
   nothing is displayed on the window !!
