Thanks much for your answer!
I don 't manage to pass the vertex_list to the display.DisplayShape, I get
following error message ( I gave a look in the OCCViewer.py and AIS.py but
since I am new in Python I couldn t solve the prob )
ERROR:
Traceback (most recent call last):
File "D:\DATA_PYTHON_D\PYTHONOCC\mon_test_5.py", line 102, in montest
display.DisplayShape( liste , update=True )
File "C:\Python26\lib\site-packages\OCC\Display\OCCViewer.py", line 313,
in DisplayShape
shape_to_display = OCC.AIS.AIS_Shape(shape)
File "C:\Python26\lib\site-packages\OCC\AIS.py", line 6192, in __init__
_AIS.AIS_Shape_swiginit(self,_AIS.new_AIS_Shape(*args))
TypeError: in method 'new_AIS_Shape', argument 1 of type 'TopoDS_Shape const
&'
-------
I tried 2 codes as follows :
-------------
CODE1 :
pt = gp_Pnt ( coord_x, coord_y, coord_z )
pt_brep = BRepBuilderAPI_MakeVertex ( pt )
liste.append ( pt_brep )
display.DisplayShape( liste , update=False)
CODE 2:
pt = gp_Pnt ( coord_x, coord_y, coord_z )
vertx = OCC.BRepBuilderAPI.BRepBuilderAPI_MakeVertex(pt)
aisShape = OCC.AIS.AIS_Shape(vertx.Vertex())
liste.append ( aisShape )
display.DisplayShape( liste , update=False )
---------------
I' m running PythonOCC 0.4 on win XP with the included OpenCASCADE / Python
2.6
Thanks for any hint!
