NAME

6       Surface - A utility for drawing perspective picture of a function of
7       two variables with hidden lines removed.
8

SYNOPSIS

10       EZSRFC - Draws a perspective picture of a function of two variables
11       with hidden lines removed. The function is approximated by a two-
12       dimensional array of heights. Use EZSRFC only if the entire array is to
13       be drawn, the data points are equally spaced in the X-Y plane, there
14       are no stereo pairs, and scaling is chosen internally.
15
16       PWRZS - A character-plotting routine for plotting characters in three-
17       space when using SRFACE.
18
19       SETR - Establishes certain constants so that SRFACE produces a picture
20       whose size changes with respect to the viewer's distance from the
21       object.  It can also be used when making a movie of an object evolving
22       in time to keep it positioned properly on the screen, saving computer
23       time in the bargin.  Call it with r0 negative to turn off this feature.
24
25       SRFACE - Draws a perspective picture of a function of two variables
26       with hidden lines removed. The function is approximated by a two-
27       dimensional array of heights.
