and do the tutorial that you find there.

@Magicat-0 if you were looking for examples of flow visualization, the dataset used here as well as the tutorial are good examples of using integeral curve stuff in VisIt.

We don't have flow data here but we could kinda sorta fake it if we wanted to do that at some point in the future. If we can assign a label to every point in our CT dataset as IN or OUT of a blood vessel and for those that are IN we could identify how close to the wall it is (as well as the local vessel diamater), then we could probably paint a vector field on top of it what would represent what an average person's blood flow is through the various vessels. With that faked flow field, we could do some interesting things. Even better, we could fake the flow field over one cycle of a person's heart beat so we'd have a time varying flow. I am sure there is probably data/models that we could use to do that though it would not be easy.

Maybe put this as a project on the todo list.
