Python Tracing Revisited

Background

Try this:

1. Start ParaView (paraview -dr)
2. Start Trace
3. Create Wavelet, Apply
4. Create Clip, Apply
5. Stop Trace

Here's how the generated trace looks in various versions:

ParaView 4.0.1 # ********** ParaView Version 4.0.1 ********************* try: paraview.simple except: from paraview.simple import * paraview.simple._DisableFirstRenderCameraReset() Wavelet1 = Wavelet() RenderView1 = GetRenderView() DataRepresentation1 = Show() DataRepresentation1.EdgeColor = [0.0, 0.0, 0.5000076295109483] DataRepresentation1.SelectionPointFieldDataArrayName = 'RTData' DataRepresentation1.ScalarOpacityUnitDistance = 1.7320508075688779 DataRepresentation1.Representation = 'Outline' DataRepresentation1.ScaleFactor = 2.0 Clip1 = Clip( ClipType="Plane" ) RenderView1.CameraPosition = [0.0, 0.0, 66.92130429902464] RenderView1.CameraClippingRange = [46.35209125603439, 92.97512386351] RenderView1.CameraParallelScale = 17.320508075688775 Clip1.Scalars = ['POINTS', 'RTData'] Clip1.ClipType = "Plane" active_objects.source.SMProxy.InvokeEvent('UserEvent', 'ShowWidget') a1_RTData_PVLookupTable = GetLookupTableForArray( "RTData", 1, RGBPoints=[43.34006881713867, 0.23, 0.299, 0.754, 276.68310546875, 0.706, 0.016, 0.15], VectorMode='Magnitude', NanColor=[0.25, 0.0, 0.0], ColorSpace='Diverging', ScalarRangeInitialized=1.0, AllowDuplicateScalars=1 ) a1_RTData_PiecewiseFunction = CreatePiecewiseFunction(\ Points=[0.0, 0.0, 0.5, 0.0, 1.0, 1.0, 0.5, 0.0] ) DataRepresentation2 = Show() DataRepresentation2.EdgeColor = [0.0, 0.0, 0.5000076295109483] DataRepresentation2.SelectionPointFieldDataArrayName = 'RTData' DataRepresentation2.ScalarOpacityFunction = a1_RTData_PiecewiseFunction DataRepresentation2.ColorArrayName = ('POINT_DATA', 'RTData') DataRepresentation2.ScalarOpacityUnitDistance = 1.8307836667054274 DataRepresentation2.LookupTable = a1_RTData_PVLookupTable DataRepresentation2.ScaleFactor = 2.0 RenderView1.CameraClippingRange = [42.19973957146408, 98.2020791247405] a1_RTData_PVLookupTable.ScalarOpacityFunction = a1_RTData_PiecewiseFunction Render()

ParaView >4.1.0 (development) # ******* ParaView Version 4.1.0-600 (After ParaView Pipeline Controller Changes) **** try: paraview.simple except: from paraview.simple import * paraview.simple._DisableFirstRenderCameraReset() Wavelet0 = Wavelet() RenderView0 = GetRenderView() UniformGridRepresentation0 = Show() RTData_PiecewiseFunction = CreatePiecewiseFunction(\ Points=[0.0, 0.0, 0.5, 0.0, 276.8288269042969, 1.0, 0.5, 0.0] ) RTData_PVLookupTable = CreateLookupTable(\ RGBPoints=[37.35310363769531, 0.231373, 0.298039, 0.752941, 157.0909652709961, 0.865003, 0.865003, 0.865003, 276.8288269042969, 0.705882, 0.0156863, 0.14902], ScalarRangeInitialized=1.0 ) ScalarBarWidgetRepresentation0 = CreateScalarBar( ComponentTitle='', Title='RTData' ) GetRenderView().Representations.append(ScalarBarWidgetRepresentation0) UniformGridRepresentation0.ScalarOpacityFunction = RTData_PiecewiseFunction UniformGridRepresentation0.LookupTable = RTData_PVLookupTable RenderView0.CameraPosition = [0.0, 0.0, 66.92130429902464] RenderView0.CameraParallelScale = 17.320508075688775 Clip0 = Clip() # toggle the 3D widget visibility. active_objects.source.SMProxy.InvokeEvent('UserEvent', 'ShowWidget') UnstructuredGridRepresentation0 = Show() UnstructuredGridRepresentation0.ScalarOpacityFunction = RTData_PiecewiseFunction UnstructuredGridRepresentation0.LookupTable = RTData_PVLookupTable Render()

The one major difference between this trace and the one generated by 4.0.1 is that we have scalar bar shown in this trace -- since ParaView now shows the scalar bar automatically.
