Introduction to Patch Objects
A patch graphics object is composed of one or more polygons that may or may not be connected. Patches are useful for modeling real-world objects and for drawing 2- or 3-D polygons.
Multifaceted Patches
This example shows how to define a 3-D patch object and illustrates flat and interpolated face coloring.
How Patch Data Relates to a Colormap
Control the relationship between patches and the colormap.
Differences Between Colormaps and Truecolor
Decide whether to use a colormap or truecolor in your visualizations.
Displaying Complex Three-Dimensional Objects
This example shows how to create and display a complex three dimensional object and control its appearance.
