It is also possible to select the most recently used resolution. The ParaView Save Screenshot and Save Animation dialogs now allow you to select the resolution from a list of commonly used presets. Resolution presets for screenshots and animations Both tutorials are now part of the ParaView Documentation website. The ParaView Self-directed Tutorial has written guidance and background and can be followed independently. The ParaView Classroom Tutorials, are meant for following along with an instructor. New ParaView TutorialsĪvailable ParaView tutorials are of two types. Note that the widget for selecting the Y-axis array is only shown if the option to use gradient is disabled. They are only visible when the advanced properties option is toggled on. The new properties are availabe in the Volume rendering section of the Properties panel. New Properties that control 2D transfer functions “Temp” and three boxes defining 2D Gaussian profiles that define the transfer function.ĢD transfer function applied to simulation data. A box can be deleted by clicking on it to select it and pressing the Delete key on the keyboard.ĢD transfer function editor in ParaView showing a 2D histogram of arrays “Pres” vs. The color and opacity of the box can be changed by activating the color chooser dialog using the new tool button provided on the right hand side of the editor. The box can be resized by holding and dragging any of the four corners of the box. The box can then be moved by left-clicking, holding and dragging the mouse cursor anywhere inside the bounds of the box. Once the 2D transfer function editor is activated, a transfer function box can be added by double clicking anywhere inside the bounds of the histogram. These regions can be dragged and resized over the 2D histogram to change the overall function.

Each region is assigned a user-specifiable color and opacity which are distributed in the box area as a 2D Gaussian distribution. You can add as many of these regions as you like to customize the transfer function. ParaView’s new 2D transfer function editor allows you to generate a 2D transfer function via rectangular regions of interest. Hovering over a pixel/point in the histogram shows the data values for the histogrammed arrays as well as the density. A legend on the right shows the density range. The histogram is displayed as a grayscale image where white indicates the highest density and black indicates lowest density.

Changing the number of bins triggers an update to the histogram based on whether or not the Automatic histogram property is enabled.ĢD Histogram in ParaView’s color opacity editor. The editor displays the 2D histogram of the chosen scalar field with the number of bins defined by the Number of histogram bins property. When you enable the Use 2D transfer function checkbox, the color opacity editor switches to the 2D transfer function editor. Histogram2D filter Transfer Function Editor The output of this filter is a one-component vtkImageData of type double that can be visualized in ParaView’s render view as an image slice. ParaView has a new filter called ExtractHistogram2D to compute 2D histograms for most types of vtkDataSets over two different data array components or their gradient magnitudes. This histogram helps highlight areas where interesting relationships between the two fields exist. To aid in the definition of 2D transfer functions, it is useful to compute a 2D histogram over the two different scalar fields of choice. The new functionality also provides for a special mode where a scalar field can be coupled with its gradient magnitude that enhances “edges” in the scalar values.

This enables the visualization to compare and contrast spatial features of the two fields. 2D transfer functions enable the color and opacity of a data sample to be determined by the value of two separate scalar fields. ParaView’s user interface now allows you to define and edit 2-dimensional transfer functions for volume visualization of structured data. New features Advanced multi-channel volume visualization
