![]() Not infrequently, seemingly odd choices of scalar values that required a large number of decimal places would be chosen for labels. These numbers were chosen by subdividing the numeric range assigned to the color legend into evenly spaced intervals. One of the complaints with the previous color legend involved the numbers chosen for labels. The new color legend has some key differences from its older counterpart. For ParaView 5.4, we have added a new color legend implementation that resolves a number of existing bugs and paves the way to make adding features easier in the future. The previous implementation made it challenging to debug when problems arose and difficult to augment when new features were needed. The color legend’s versatility unfortunately came with a somewhat complex implementation. Over the years, ParaView’s color legend features have expanded to cover numerous usage scenarios, including annotating specific values with text, showing the color assigned to NaN values, showing categorical colors, and controlling different elements of the color legend such as font size and style. ParaView’s color legend provides an important link between color and data values, and is a critical component of many visualizations. Department of Energy’s National Nuclear Security Administration under contract DE-NA-0003525.Pseudo-coloring of surfaces and volumes is one of ParaView’s primary methods of displaying data. Sandia National Laboratories is a multi-mission laboratory managed and operated by National Technology and Engineering Solutions of Sandia, LLC., a wholly owned subsidiary of Honeywell International, Inc., for the U.S. Note - there seems to be a bug in ParaView, where if you click on the Contour filter again, it will ask you to apply.In the pipeline browser, I also turned off visibility for the Contour filter. Change the pulldown box next to the blue + to be Contour.Optional - I increased the scale factor by about 5X. Turn all variables on, and hit the apply button. We will also add glyphs to the streamline points. Our goal is to create a set of streamlines from a vector field, place points on this set of streamlines, and animate the point down the streamlines.If you have a vector field in your data, you can animate a static dataset.Change Backface Style - Representation to Cull Backface.Slide down a few pages until you find Backface Style. It is possible to change the backface style of a wire frame object.Turn visibility of can.ex2 on, and Representation of Wireframe.Choose Scalars of “Quality”, and Lower Threshold of 4 and Upper Threshold of 1000.Next, we want to only look at those cells that are below some threshold of quality.Filters → Alphabetical → Mesh Quality.Mesh quality is created using the Mesh Quality filter.For instance, this example will create a vector representing the acceleration in the X and Y plane. Build the vector equation using the iHat, jHat and kHat buttons on the calculator.To see the ranges of these variables over the whole mesh, look in the Information tab. ![]() You can now visually see average acceleration, maximum acceleration and average displacement of each cell. Filters → Temporal → Temporal Statistics.We now have a ClipByScalar filter (sometimes incorrectly know as an IsoVolume filter). Turn Scalars to Temp, enter a Value of 400, and hit Apply. ![]()
