Our shape-based transfer function approach (IEEE Pacific Visualization 10) is employed to highlight the aneurism.

Since version 2.0 Voreen supports basic flow visualization techniques, as streamlines, hedge hogs and LICs.

Rendering of refraction effects (ACM SIGGRAPH Courses 09).

Glyph-based SPECT visualization (IEEE Visualization 08).

Performance enhancement with occlusion frustums (VG08).

Interactively cutting and flipping open the hand data set (WSCG08).

The head of the Visible Human is flipped open using a three-way cutting template (WSCG08)

The integration of shadows allows a higher degree of realism (WSCG08)

In volume rendering also semi-transparent shadows may occur (WSCG08)

Internal labels occlude parts of the visualization and have a negative effect on the spatial comprehension. In contrast 3D internal labels can give additional shape cues (VMV07).

In combination with other illustrative rendering techniques 3D labels can be used to mimic the style of anatomical atlases (VMV07).

Our VMV07 paper on multimodal visualization describes how to visualize multimodal data sets by using glyphs.

To visualize motion within still images we have developed appropriate visualization techniques (VMV06, VMLS07)

Visualization of angiography data sets is a critical task requiring optimized depth perception. With the shown techniques we were able to improve the depth impression (SG06, UCDMV97).

Application of a 3D region of interest (ROI) in Voreen. Different visual representations can be used inside and outside the ROI. The underlying technique is described in our VMV05 paper.

Voreen makes it easy to apply illustrative rendering techniques such as toon shading and contour highlighting.

Also the combination of other rendering techniques can be achieved easily. The Figure shows a focus and context visualization by combining Phong shading with toon shading as well as edge enhancement and silhouette highlighting.

Spatial comprehension can be improved by applying edge enhancement techniques.
