Title:
  wrong vis. routine: single dipole no rotational symmetry

Status in “antennavis” package in Ubuntu:
  New

Bug description:
  Dear Antennavis maintainers,

  I am Bohumir, co-author of http://yagi-logper.sourceforge.net/.
  Thanks for maintaining antennavis package. I am fond of antennavis.

  I believe I found a small bug in the antennavis visualization routines.
  It appears, for example, when you give Antennavis a single dipole as input, as
  attached. Result should be a rotationally symmetric around the axis of
  the dipole, but it is not.

  Following three lines, in PlotPoint() function, VisField.c file are
  wrong:

     glRotatef(azimuth, 0.0, 1.0, 0.0);
     glRotatef(elevation, 1.0, 0.0, 0.0);
     glTranslatef(0.0, 0.0, dist * POINT_DIST_SCALE);

  They should be replaced by:

     glRotatef(elevation, 0.0, 1.0, 0.0);
     glRotatef(azimuth, 0.0, 0.0, -1.0);
     glTranslatef(0.0, dist * POINT_DIST_SCALE, 0.0);

  The above change will fix the problem.

  I would be very glad if you can implement the above change.
  I can supply it in a form of patch if needed.

  Best,
  -Bohumir
