Interpolate between two cells paraview how to#

In this example we will show how to animate your data set. Change the starting value to -8 and the ending value to 8.This will bring up a dialog, and will set the start and end. We want to create a track that is Slice, Slice Offset Values.In the Animation View, change Mode to Sequence, and number of frames to 400.Open disk_out_ref.exo, all variables on, Apply.If you closed it, bring up the Animation View.Our goal is to move a slice through our dataset over time. In this example we will show how to animate a filter. In the previous example we showed how to manipulate the camera using the Animation View tools. You will see a yellow circle with white spheres.

We are going to move the camera along a spline. Then, copy these control points, and then copy them into the 3d simulation you want to animate. One way to create tracks in 3d space is to use Interpolate Camera Location, and place the control points onto a plane. Then, follow the directions above.Įxperiment by adding more keyframes and different camera angles. You can also create an intermediate destination for the can by going to the Animation Keyframes dialog, and selecting New. Move the can dataset back into the center of the screen.

An Animation Keyframes dialog will open.

Left click on the white section of the camera row that just appeared.

Change Orbit to Interpolate Camera Position. We want to move the camera to follow the can. We are going to move the camera along a straight line. By turning visibility on for your whole dataset, you can follow the cell but display all of your data. If needed, you can turn the cell's Opacity (Properties tab) to 1%, making it disappear. Note that you must keep visibility on for this cell. This means that you can choose one cell, run the Extract Selection filter, and follow this cell. Note that the follow data option will follow the data from whatever filter is highlighted. We are going to make the camera follow the data. Default motion is Orbit, so click the blue +. We are going to make the camera rotate around our data. AMR (Adaptive Mesh Refinement) data does not work with the Temporal Interpolator.

Note that this only works with data that stays consistent through the whole time sequence.

ParaView is interpolating between frames, and making 200 time steps. Notice that the can motion is now smooth.

Filters → Temporal → Temporal Interpolator.

In the Animation View window, change the mode to Sequence, and the No.

Obviously, this is dependent on the whether ParaView can keep up with this frame rate!

Set the Duration to 10, and ParaView will animate over all time in 10 seconds. Note - this can also be used to speed up datasets with a large number of time steps.We are saying that we want the whole animation to last 100 seconds. Notice that the can motion is now very slow. In the Animation View window, change the mode to Real Time, and the Duration to 100.

Grab the slider bar and move it back and forth.(If you changed the order of the steps above, you may need to click "Rescale to Data Range".Drag the can around with the left mouse button.On the Properties tab, select all variables and press the Apply button.Open the data set can.exo, which can be downloaded at.This tutorial deals with advanced topics in animations.
