executive summary ¶

The large y dimension values: -805788 are resulting in a loss of precision due to use of default streaming in the exported VRML2 geometries. Six mother volumes end up exactly overlapping their six daughters, they are very close concentric tubs.

G4Point3D streaming ¶

global/HEPGeometry/include/G4Point3D.hh:

33 #include "globals.hh"
34 #include <CLHEP/Geometry/Point3D.h>
36 typedef HepGeom::Point3D<G4double> G4Point3D;

external/build/LCG/geant4.9.2.p01/source/visualization/VRML/src/G4VRML2SceneHandlerFunc.icc:

209         G4Point3D point = polyhedron.GetVertex(i);
211         point.transform( *fpObjectTransformation );
214         fDest <<                   point.x() << " ";
215         fDest <<                   point.y() << " ";
216         fDest <<                   point.z() << "," << "\n";

std::ofstream     fDest ;

Probable Fix ¶

external/build/LCG/geant4.9.2.p01/source/visualization/VRML/src/G4VRML2FileSceneHandler.cc:

041 #include <iomanip>   // SCB
...
190
191     G4cerr << "Using setprecision(5) and fixed floating point notation for veracity of output [SCB PATCH] " << G4endl;
192     fDest << std::setprecision(5) << std::fixed ; // SCB
193
194 }

distinct volume count discrepancy ¶

Before including volume name metadata line in src name:

sqlite> select count(distinct(src)) from shape ;
12223

After including the the name line, are 6 more distinct:

simon:export blyth$ echo "select count(distinct(src)) from shape ;" | sqlite3 -noheader g4_00.db
12229

This suggests six absolute position duplicated shapes with different volume names

confirmation of shape overlapping ¶

Hashing the shape with name excluded confirms issue. The dodgy dozen, six pairs of volumes are precisely co-located:

sqlite> select hash, group_concat(name), group_concat(id)  from shape group by hash having count(*) > 1 ;
hash                              group_concat(name)                                                                                                                           group_concat(id)

initial hypothesis ¶

The closeness of the two tubs with difference of radii 7.94-6.55=1.39 mm (representing the thin stainless steel source shell) triggered some overlap (vertex moving) code in the export that results in the merging of the volumes.

This merging got done twice resulting in exactly the same shape on both occasions.

NOPE: tis simple imprecise export formatting

Look for others with those names ¶

All six of those names are overlapped:

Toggle the bbox for a volume from commandline, unfortunately need to use internal node id, not my name:

simon:export blyth$ curl "http://localhost:35668/setFieldValue?node=265938224&field=5&value=TRUE&link=referer"

simon:export blyth$ curl "http://localhost:35668/setFieldValue?node=265938224&field=5&value=TRUE&link=referer"
simon:export blyth$

Works with external names too:
