Drawing volume specifications
The geometrical parameters of the volumes can be displayed via the GDSPEC routine (corresponding to the
DSPEC interactive command). This facility provides a detailed picture of a particular piece of the detector.
The set of geometrical specifications of all the descendants of a given node on the tree, can be obtained each
on a separate picture with the routine GDFSPC (DFSPC interactive command).
CALL GDSPEC
(CHNAME)
CHNAME
(CHARACTER*4) volume name;
Draws a picture showing all specifications for a given volume. An example of use of GDSPEC can be found
in Fig. 15.
The following information on the volume are presented in a single frame:
• the volume daughters (one level down in the geometrical tree);
• a space view of the volume (with θ=45 and φ=135);
• a front view cut;
• a side view cut;
• the axes of the local coordinate system;
• a human figure;
• the scale;
• the shape type;
• all the numerical parameters that define the volume.
In drawing the volumes GDSPEC turns on the sets visibility (’SEEN’) attribute for the volume CHNAME itself
and its direct descendents. The setting of drawing options (HIDE, CVOL, FILL ...) will be respected, allowing
to customise the drawing. An example is shown in Fig. 16.
CALL GDFSPC (CHNAME,ISORT,INTER)
Draws on separate pictures the full set of GDSPEC for the geometrical tree starting from CHNAME, i.e. calls
GDSPEC for the volume CHNAME and for all its descendants.
CHNAME
ISORT
INTER
(CHARACTER*4) volume name;
(INTEGER) alphabetic sorting flag;
=1 all the volumes will be drawn in ascending alphabetic order according to their name;
≠1 the volumes will be drawn in the order in which they have been created;
(INTEGER) interactive/batch version flag;
=1 the routine will prompt the user at each plot before doing a clear screen;
≠0 the routine will clear automatically the screen before starting a new frame.
Note: INTER should be set to 1 when using the interactive version of GEANT and to any other
value when using a batch version.
