Przemek posted a new comment:
I just tried to use this:
vtkExporter = export.VTKExporter('/tmp/vtkExporterTesting')
vtkExporter.exportSpheres(what=dict(dist='b.state.pos.norm()'))
But I had an error:
ValueError Traceback (most recent call last)
/usr/bin/yade in <module>()
/usr/bin/yade in tempCalc()
202
203 vtkExporter = export.VTKExporter('vtkExporterTesting')
--> 204 vtkExporter.exportSpheres(what=dict(dist='b.state.pos.norm()'))
205
206 #export.textExt('test.txt', format='x_y_z_r_attrs',
attrs=['b.getTemp()'], comment='temp')
/usr/lib/x86_64-linux-gnu/yade/py/yade/export.py in exportSpheres(self, ids,
what, comment, numLabel, useRef)

429 # write additional data from 'what' param

In case when I used export to txt file, I get:
#format x_y_z_r_attrs
# x y z r temp

1 0 0 0.55 42.3553
2 0 0 0.55 44.7105
3 0 0 0.55 47.0658
4 0 0 0.55 49.421
And after text2vtk:
# vtk DataFile Version 3.0.

POINTS 4 double

4 0 0
POINT_DATA 4
SCALARS radius double 1

0.55
SCALARS temp double 1
LOOKUP_TABLE default

So, in txt I have 5 particles and in vtk file 4... wierd...
