I would like to have a program which tests a geometry written in GDML format.
I have used the load_gdml program, located at geant4.9.2/examples/extended/persistency/gdml/G01 to read any GDML file. I have changed vis.mac macro to output a DAWNFILE and add the environmental variable:
setenv G4DAWNFILE_VIEWER david ,
to generate automatically a g4david.prim file with the intersected volumes, using the DAVID program. The DAVID and DAWN versions that I use are: david 1.36a and dawn 3.88a I have seen that there is a limitation in DAVID program:
> Supported shapes > > The following shapes defined in the DAWN format > are supported at present: > > Box, Column, Cons, Parallelepiped, Sphere, Trd, Trap, Tubs
So I have used geotest.cc with write_gdml.mac macro which generate a geometry with only G4tubs and G4Box in a wtest.gdml file.
I have used load_gdml to generate the g4david.prim file and it shows me some intersection errors.
Even adding in vis.mac file:
It gives me also intersection errors. It is a limitation of DAVID and /geometry/test codes? Is the geometry from G02 example wrong?.
Somebody has a better idea to test the gdml geometries in a easy (graphic) way?
