3D Graph is a 3 dimensional equation plotter. Plotted on an imaginary

xyz coordinate system. You have the ability to rotate the graph,

determine the object to image perspective distances, adjust the X and Y

ranges as well as their increments, state translations of both the X

and the Y axes and scale on both X and Y axes.

So experiment with the default equation then try some of the others at

the end of the doc.

Menu

Z:=2*COS(0.1*(X^2+Y^2)) The equation may be edited with backspace,

cursor keys, and the home key

YRot: Rotate along Y axis suggested range (-1.0 thru 1.0)

XRot: Rotate along X axis range (0.6 - 1.4)

Obj : distance of object from origin (20-100)

Im : distance of Image(screen) from origin (500-1000)

XRan: most equations should have a range of 10 which means (-10 to 10)

YRan: most equations should have a range of 10 which means (-10 to 10)

XInc: the step value of the loop (2.0 to 0.25)

YInc:

XTr : X Translation factor (200)

YTr : Y Translation factor (100)

ScX : Scale X (2.0)

ScY : Scale Y (1.0)

When you have made the adjustments ESC will start the plot.

Some error checking is done but overflow errors will crash the system.

Try these:

Z := 0.2*(0.1*(X/Y)^2-0.1*(Y/X)^2)+6*EXP(-1.9*(X^2+Y^2))

YRot:0.8 XRot:1.8 XRange:4 YRange:5 Obj:45 Im:900

Inc:0.25

Z := 0.5*(-0.1*(X/Y)^2-0.3*(Y/X)^2)+8*EXP(-0.1*(X^2+Y^2))

YRot:0.8 XRot:1.4 XRange:10 YRange:10 Obj:75 Im:900

Inc:0.50

Z := 0.02*(X*X*Y/X/Y)

YRot:0.3 XRot:1.2 XRange:10 YRange:10 Obj:50 Im:800

Inc:0.50

Z := 1/12*(SIN(X)*SIN(Y))

YRot:0.6 XRot:0.8 XRange:4 YRange:4 Obj:45 Im:900

Inc:0.25

Z := 2*COS(0.1*(X^2+Y^2))-2*SIN(0.1*(X^2+Y^2))

YRot:0.3 XRot:1.2 XRange:10 YRange:10 Obj:50 Im:750

Inc:0.25

Z := 0.5*(0.2*(X/Y)^2-0.2*(Y/X)^2)

YRot:0.3 XRot:1.8 XRange:10 YRange:10 Obj:45 Im:900

Inc:0.50

Z := 3*SIN(-0.05*(X^2-Y^2))-2*COS(0.1*(X^2+Y^2))

YRot:-0.6 XRot:1.2 XRange:10 YRange:10 Obj:50 Im:550

Inc:0.50
