3-D Visualization

Isocaps Add Context to Visualizations

Isocaps are planes that are fitted to the limits of an isosurface to provide a visual context for the isosurface. Isocaps show a cross-sectional view of the interior of the isosurface for which it provides an end cap.

The following two pictures illustrate the use of isocaps. The first is an isosurface without isocaps.

The second picture shows the effect of adding isocaps to the same isosurface.

Other Isocap Applications

Some additional applications of isocaps are

• Isocaps used to show the interior of a cut-away volume.
• Isocaps used to cap the end of a volume that would otherwise appear empty.
• Isocaps used to enhance the visibility of the isosurface limits.
