dump()¶

class pyg4ometry.stl.Reader(filename, solidname='stl_tessellated', scale=1, centre=False, registry=None, forcebinary=False)¶

STL file reader

Parameters:

filename (str) – Input STL filename
solidname (str) – Name of the solid to be created
scale (float) – Scaling of STL (e.g. for units)
centre (boolean) – Flag to centre STL solid
registry (Registry) – Registry to add solid to
forcebinary (boolean) – Forces to load this STL file in binary format, otherwise the file format is determined from whether it starts with the string ‘solid’

filename¶

_registry¶

solidname¶

worldVolumeName = ''¶

facet_list = []¶

scale¶

solid¶

_load_ascii(data)¶

Load ASCII STL file from bytes instance

_load_binary(data)¶

Load binary STL file from bytes instance

extent()¶

Compute the axis aligned extent of the STL solid.

Returns:: list of minima and maxima in 3 axes
Return type:: [[xmin,ymin,zmin],[xmax, ymax, zmax]]

extentCentre()¶: Translate STL mesh to centre of the extent

translate(translation=[0, 0, 0])¶

Translate STL mesh by translation

Parameters:: translation (list(3) or array(3)) – Vector to translate mesh

getSolid()¶

Get geant4.solid

Returns:: G4Tesselated for STL
Return type:: TessellatedSolid

getRegistry()¶: Return registry

visualise()¶: View solid directly by using a dummy world

writeDefaultGDML(filename='default', gmad_tester=False)¶

Write the tessellated solid loaded from STL to GDML. The placement has no rotation or translation. The world material is G4_Galactic, the solid material is G4_Fe.

Parameters:

filename (str) – Output file name
gmad_tester (boolean) – Flag for writing BDSIM gmad tester
