Christian, Thanks for getting me started. And sorry it took me so long to respond. I've been moving pretty slow on this project.
Anyway, I've done the following with my script: import math input = self.GetInputDataObject(0,0) output = self.GetOutputDataObject(0) numPoints = input.GetNumberOfPoints() points = input.GetPointData() SurfCvg = 0 for i in xrange(numPoints): d = points.GetArray('d').GetValue(i) coords = input.GetPoint(i) z = coords[3] h = 0.00015 - abs(z - 0.00015) - 0.5*d H0 = 2*h/d if (H0 < 0.002) SurfCvg = SurfCvg + 0.25*math.pi*d*d Theta = SurfCvg/(0.01*0.001) outputarray = vtk.vtkStringArray() outputarray.SetName("Surface Coverage") outputarray.SetNumberOfTuples(1) outputarray.SetValue(0, "%d" % (Theta)) output.GetRowData().AddArray(outputarray) First of all, am I getting the z coordinate correctly? I haven't been able to find an answer to that in my searching. Secondly, my end goal is to plot the value of Theta over time for my dataset. Do I have the output stuff done right, and where do I go from there? Thanks in advance. -Scott On Sat, Nov 3, 2012 at 3:53 AM, Christian Richter <christian.rich...@ovgu.de > wrote: > Hi, > > in a programmable Filter do something like this: > > import math > input = self.GetInputDataObject(0, 0) > output = self.GetOutputDataObject(0) > COUNT=input.GetNumberOfPoints() > pd=input.GetPointData() > m=0 > v=0 > for i in xrange(COUNT): > r=pd.GetArray('radius').GetValue(i) > v=v+((4.0/3.0)*math.pi*r*r*r) > m=m+pd.GetArray('Mass').GetValue(i) > outputarray = vtk.vtkStringArray() > outputarray.SetName("Text") > outputarray.SetNumberOfTuples(1) > outputarray.SetValue(0,"N=%d\nV=%1.6f m³\nm=%1.6f kg" % (COUNT,v,m)) > output.GetRowData().AddArray(outputarray) > > Attention: if you save this to a state-file change the ³ to 3 because it > will not be escaped and you can not load the state anymore. > > best wishes, > Christian > > Am 02.11.2012 21:49, schrieb Scott Ripplinger: > > I need to sum all the values in a vector of a scalar property.
