Hi all,
I'm a rather novice phigs/pex programmer and I'm having some problems
using the phigs sample implementation. I'm using the X11R5 pl3 on a SUN
Sparcstation 1+ 8 bit color.
I'm writing yet another program that is able to show and rotate molecules.
My problem is that I have to draw many balls on the display, with many
different colors. I thought that it would be wise to have a structure that
is a sphere (and another for the bond) and than scale, translate and color it
as needed executing the struct within the structs that describe the various
molecule substructures.
With the code I append I get only wireframes, not solid with color.
What am I doing wrong?
Reading the docs it should work.
Thanks in advance.
Ciao
Stefano

      tmp_vector.delta_x = types[i].radius;
      tmp_vector.delta_y = types[i].radius;
      tmp_vector.delta_z = types[i].radius;
      pscale3(&tmp_vector, &status, temp_mat);
      pset_local_tran3(temp_mat, PTYPE_REPLACE);
    }
