Isosurface Extraction

Isosurface extraction is a technique used in computer graphics and scientific visualization to extract and render a surface that represents points of equal value within a 3D scalar field. This method is commonly applied in fields such as medical imaging, engineering, and fluid dynamics to visualize volumetric data.

Opening the Isosurface Extraction Workspace in Voreen

To access the volumepreprocessing-isosurfaceextraction.vws workspace in Voreen, follow these steps:

1. Go to File → Open Workspaces
2. Navigate to Workspaces
3. Select volumepreprocessing-isosurfaceextraction.vws
4. Click Open and switch to Application Mode

Operations in the Properties Space

• Volume Input:
  Use Clear Volume to remove the current input file and Load Volume to load new data.
• Isosurface Extraction:
  Select a method for computing the isosurface and set an isovalue.
• Geometry Output:
  Save the extracted isosurface in various file formats, such as .stl or .obj.

Advanced Isosurface Extraction

Switching to Network Mode in this workspace allows for more customization of the isosurface extraction process. The Properties panel of the IsosurfaceExtractor processor provides additional options for fine-tuning the extraction method. This includes smoothing, which is disabled by default but can be enabled for refined results.
