-volumeplot: shows the generated mesh

This section enables the regeneration of the grid and shows the discretised material boundaries as generated from the geometric primitives specified so far.

• showpartition= [yes|no]:
  Parallel-only: Flags, whether the partitioning in subvolumes shall be encoded in different material colours for each subvolume.
• showlines= [yes|no]:
  Flags, whether the materialplot shall have lines where the material boundaries cross gridplanes.
• text= [yes|no]:
  Flags, whether the annotation-text that has been specified via text()= bla bla in the section -general should be plotted together with the material boundaries.
• scale= SCALE:
  The initial zoom factor of the resulting plot.
• plotopts= ANY STRING CONTAING OPTIONS FOR gd1.3dplot:
  gd1 does not display the data itself, but writes a datafile for gd1.3dplot and starts gd1.3dplot to display these data.
  Useful options are:
  • -colorps : Produce colour PostScript and quit
  • -greyps : Produce grey-scale PostScript and quit
  • -geometry X11-GEOMETRY : Initial geometry for the X11 window of gd1.3dplot.
  • -o FILENAME : If a PostScript is requested, the file written is FILENAME. The default filename is dataplot.ps.
• eyeposition= (XEYE, YEYE, ZEYE):
  This specifies the initial eyeposition for the 3D plot that will be produced. As soon as the plot appears, you can interactively change the eyeposition with the buttons of gd1.3dplot, but for a complex geometry, this may take some time.

• bbxlow=,bbxhigh=,bbylow=bbyhigh=,bbzlow=,bbzhigh=:
  Specifies the coordinates of a bounding box. Only the materialboundaries that lie within the box are plotted. Use this if you want to see the materialdistribution in a plane.
• rotx= PhiX, roty= PhiY, rotz= PhiZ:
  This specifies the parameters of an additional rotation matrix. The data is rotated around the x-axis by an angle of PhiX, then the result is rotated around the y-axis by an angle of PhiY, and finally the result is rotated around the z-axis by an angle of PhiZ.

• doit:
  If you say "doit", the relevant settings in "-mesh" are checked, the mesh is re-generated, and the material boundaries are plotted.

Example The following shows the material distribution of a waveguide twist again, this time, the parameter bbyhigh is specified such, that only the material boundaries behind the plane y=0 are shown.

 include(/usr/local/gd1/examples-from-the-manual/ggcylinder-twisted.gdf)
 -volumeplot
    eyeposition= ( 1, 2, 1.3 )
    scale= 4.5
 bbyhigh= 0
    doit

Figure 1.16: A twisted waveguide. Only the material boundaries behind the plane y=0 are shown.

Example The following shows the material distribution of a waveguide twist again, this time, the parameter roty is specified nonzero.

 include(/usr/local/gd1/examples-from-the-manual/ggcylinder-twisted.gdf)
 -volumeplot
    eyeposition= ( 1, 2, 1.3 )
    scale= 4.5
 roty= 20
    doit
