Vortex Coreline Extraction

A vortex coreline is a geometric representation that highlights the central structure of a vortex within a flow field. It provides a simplified, one-dimensional description of the rotational motion of fluid, offering valuable insights into the dynamics of vortices in simulations or experimental data.

The feature-vortexcorelineextraction.vws provides a Voreen workspace for extracting vortex corelines from 3D vector fields. To access it, follow these steps:
File → Open Workspaces → Workspaces → feature-vortexcorelineextraction.vws → Open

Once the workspace is loaded, switch to application mode, where you should see the following interface:

Operations in the Properties Space

• 3D Vector Field:
  Load the data. The processor is named "3D Vector Field" but is actually the standard VolumeSource processor, familiar from other parts of Voreen.
• Mask:
  Load a mask for the data. You can also configure isosurfaces and their isovalues.
• Filter:
  Apply a filter based on the minimum length of the corelines.
• Streamlines:
  Configure streamlines, such as their color and the number of seed points.
• Corelines:
  Adjust properties of the extracted corelines, such as color.
• Background:
  Customize the background of the visualization.
• Output:
  Save the coreline geometry in various formats.

Operations in the Canvas Space

• Adjust the camera angle by clicking and hovering.
