Wireframe plots
A wireframe plot draws an oblique, 3-D plot of a wireframe model of a
surface determined by Z = F(pc, y). An example is = :x^ - xip.
The plot drawn is the surface of the model as viewed from a specified
vantage point. This vantage point is called the eyepoint. The surface
plotted is that within a region in 3-dimensional space—called the view
volume—detennined by ranges on each of the three coordinate axes.
A wireframe plot needs two inputs to generate an output. The HP 49G
uses a two-dimensional sampling grid of points whose coordinates
provide the two inputs required. By default, the sampling grid consist of
80 points: 10 columirs by 8 rows.
The following example is a wireframe plot of z = .
