Sets the intensity for LIC pattern when using Blend shader. Select the shader that is used to combine lit and pseudocolored surface geometry with the LIC. Integration step size given in the original vector field's units.Įnable vector field normalization during integration. When the two pass LIC is enabled, the number of steps used in the second pass is set automatically. Number of integration steps used in the first LIC pass. The following table and figure have a basic description of the parameters with links to more information. Clicking on the properties panel's Advanced button will display all of the available parameters. Once active the algorithm's run-time tunable parameters are accessed from the Properties panel in the ParaView client GUI. Once loaded the surface LIC is activated by selecting it from the drop-down list of Representations. For more information on ParaView plugins see the plugin how to. The plugin may be loaded by opening the Tools menu and selecting Manage Plugins and finally selecting the surface LIC plugin and clicking Load on both client and server. Surface LIC may be used in ParaView by loading the Surface LIC Plugin. This document describes the parallelization, features, and optimizations facilitating interactive data exploration that were released with ParaView 4.1 and VTK 6.1.įigure 2 Run time tunable parameters for the surface LIC plugin in ParaView's display Properties panel. ParaView's implementation has been designed to work with composite data in parallel and includes a number of customizations that facilitate interactive data exploration. Some examples of ParaView's surface LIC in action are shown in Figure 1. ParaView supports LIC on arbitrary surfaces via the Surface LIC plugin. Originally the technique was developed for use with 2D image based data but has since been extended to work on arbitrary surfaces and volumes. The line integral convolution(LIC) vector field visualization technique convolves noise with a vector field producing streaking patterns that follow vector field tangents. Figure 1c Surface LIC applied to a contour of a CFD simulation of air flow in an office. Figure 1b Surface LIC applied to a multiblock CFD simulation of a NASA launch vehicle with block bounds colored by composite id. Figure 1a Surface LIC showing coherent structures in the magnetic fields of turbulent plasma. U1.append(DataSliceFile.GetCellData().GetArray('U1').Figure 1 Examples of ParaView's surface LIC in action. NumCells = DataSliceFile.GetNumberOfCells() IntegrateVariables1 = integrateVariables(Input=slice1)ĭataSliceFile = (integrateVariables1) The following code worked for me: from paraview.simple import *ĭisp1OpenFOAM = FindSource('disp1.OpenFOAM') I wanted to edit my question for future-readers. I solved my problem and updated my code little bit. Can you help me to correct this? Thank you. I checked Google to get some advice but I couldn't find my mistake. U10=data.GetCellData().GetArray("U1").GetValue(1) # This is the line no. This is the script that I am using: import paraview.simple as pvs However, I get error as: Traceback (most recent call last):ĪttributeError: 'NoneType' object has no attribute 'GetValue' I press apply and after that, I run Python Shell and run my script. To use Python Shell, I open Paraview and select my mesh regions and cell arrays. This is easy to be done manually but I want to do this using Python Shell as my further calculations require me to do some math. I want to access to the result of U using Python Shell after applying integrate variables filter.
