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

3D Internal Labels
3D Internal Labels

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).

Illustrative Rendering - 3D labels
Illustrative Rendering - 3D labels

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

Glyph Rendering
Glyph Rendering

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

Motion Visualization
Motion Visualization

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

Angiogram Depth Perception
Angiogram Depth Perception

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).

3D Region of Interest
3D Region of Interest

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.

Toon Shading
Toon Shading

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

Combination of rendering techniques
Combination of rendering techniques

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.
