Surfaces and Contours in IDL

Getting Started with IDL: Surfaces and Contours

Surfaces and Contours in IDL

IDL provides many command line techniques for visualizing two-dimensional arrays, including contour plots, wire-mesh surfaces, and shaded surfaces. The new iSurface and iContour tools are also available for easy surface and contour visualization and manipulation. This chapter demonstrates just a few of the options for visualizing and manipulating data in three dimensions.

Note
To simplify obtaining useful results from the command line examples in this manual, create a bitmap buffer for your graphic windows and to use a maximum of 256 colors by entering the following command at the IDL command prompt:

DEVICE, RETAIN=2, DECOMPOSED=0
