Hi Darren,
How about:
try: paraview.simple
except: from paraview.simple import *
points_csv = CSVReader(FileName =
'/Users/magician/Documents/ParaViewTest/points.csv')
TableToPoints1 = TableToPoints(
XColumn = 'x',
YColumn = 'y',
ZColumn = 'z',
)
Show()
Calculator1 = Calculator(Function = 'vx*iHat+vy*jHat+vz*kHat')
Show()
Glyph1 = Glyph(
Vectors = ['POINTS', 'Result'],
GlyphType = 'Arrow',
SetScaleFactor = 1.0,
)
Show()
Render()
I tried on ParaView 4.1.0 of OSX.
