Wireframe plots
Wireframe plots are plots of three-dimensional surfaces described by z = f(x,y).
Unlike Fast 3D plots, wireframe plots are static plots. The user can choose the
viewpoint for the plot, i.e., the point from which the surface is seen. For
example, to produce a wireframe plot for the surface z = x + 2y –3, use the
following:
Θ Press „ô, simultaneously if in RPN mode, to access to the PLOT
SETUP window.
Θ Change
TYPE to Wireframe.
Θ Press ˜ and type ‘X+2*Y-3’ @@@OK@@@.
Θ Make sure that ‘X’ is selected as the
Indep: and ‘Y’ as the Depnd:
variables.
Θ Press L@@@OK@@@ to return to normal calculator display.
Θ Press „ò, simultaneously if in RPN mode, to access the PLOT
WINDOW screen.
Θ Keep the default plot window ranges to read:
X-Left:-1, X-Right:1, Y-Near:-1, Y-
Far: 1, Z-Low: -1, Z-High: 1, XE:0,YE:-3, ZE:0, Step Indep: 10 Depnd: 8
The coordinates XE, YE, ZE, stand for “eye coordinates,” i.e., the coordinates
from which an observer sees the plot. The values shown are the default values.
The Step Indep: and Depnd: values represent the number of gridlines to be used
in the plot. The larger these number, the slower it is to produce the graph. For
the time being we’ll keep the default values of 10 and 8 for the Step
Θ Press @ERASE @DRAW to draw the three-dimensional surface. The result is a
wireframe picture of the surface.
