Illustrative Visualization Techniques

In different research areas illustrative visualization techniques are used to convey complex information in a simplified and more abstract manner. These techniques have their origin in traditional illustration techniques like pen-and-ink techniques (e.g., stippling and hatching) and smart visibility techniques (e.g. ghosted and exploded views). Often, they are adapted to a certain application to enhance important information, such as surface shape, depth, focus-and-context relations and spatial relationships.

In our working group, we focus on both the development and improvement of existent illustrative visualization techniques and their application to several medical research areas, such as blood flow visualization and treatment planning. Thereby, we incorporate related topics that are necessary to extract the important information, e.g., differential geometry, vector field analysis and advanced GPU programming. The effectivness of the investigated and proposed techniques are assessed by means of perceptual evaluation studies.

A short summarization of our current field of research:

  • Developing of illustrative rendering techniques
  • Adapting and extending of existent techniques for anatomical structures and scenes
  • Evaluation of these techniques in a medical context is done by the perceptual evaluation research project

  • In this figure, stippling is used to depict anatomical context structures of a patient specific data set.
  • Another example of depicting shading with stippling.
  • Distance lines are generated along the cutsurface for the breakaway to aid spatial perception.
  • A tumor is highlighted by a cone breakway. Additional shading effects are employed for spatial perception.
  • An enlarged lymph node is highlighted by circle mask ghosting. Silhouette edges of structures in front are preserved.
  • Based on the focus structure silhouette (enlarged lymph nodes) the ghosting is performed. Lit-Sphere shading was employed for an illustrative look.
  • Shading of a knee is performed by a local adapted stippling due to shading maps. Additionally, border enhancement is achieved by using of silhouettes.
  • Stippling and hatching are used to visualize different anatomical structures.
  • To-be-removed segments of the liver serve as breakaway cut volume with different ranges. The liver support system is overlayed.
