Deprecated: Interactive Graph of a Function in Rectangular Coordinates in 3D

Click to enlarge

This PG code shows how to use the LiveGraphics3D Java applet to display an interactive graph of a function in rectangular coordinates. It is deprecated because Java is no longer universally supported on all web browsers and platforms.

DOCUMENT(); loadMacros( "PGstandard.pl", "MathObjects.pl", "parserPopUp.pl", "LiveGraphicsRectangularPlot3D.pl", ); TEXT(beginproblem());	Initialization: We need to include the macros file LiveGraphicsRectangularPlot3D.pl.
Context("Numeric"); Context()->variables->are(x=>"Real",y=>"Real",r=>"Real",s=>"Real",t=>"Real"); $a = - random(-1,1,2); $plot = RectangularPlot3DRectangularDomain( function => Formula("t^2+$a*s^2"), xvar => "s", yvar => "t", xmin => -2, xmax => 2, ymin => -2, ymax => 2, xsamples => 10, ysamples => 10, axesframed => 1, xaxislabel => "S", yaxislabel => "T", zaxislabel => "Z", outputtype => 4, ); if ( $a == -1) { $im = "hyperbolic-paraboloid.png"; $pop = PopUp( ["Choose","Paraboloid","Hyperbolic paraboloid"], "Hyperbolic paraboloid"); } else { $im = "paraboloid.png"; $pop = PopUp( ["Choose","Paraboloid","Hyperbolic paraboloid"], "Paraboloid"); }	Setup: We generate a string of plot data using RectangularPlot3DRectangularDomain(). Setting outputtype to something other than 4 will require you to read the source code of LiveGraphicsRectangularPlot3D.pl and familiarize yourself with the details of the LiveGraphics3D java applet. For more information on how to work with the string of plot data, see Martin Kraus's LiveGraphics3D homepage, and the excellent article by Jonathan Rogness and Martin Kraus Constructing Mathlets Quickly Using LiveGraphics3D.
Context()->texStrings; BEGIN_TEXT The graph below is called a \{ $pop->menu() \} $PAR $BCENTER \{ Live3Ddata( $plot, image => $im, size => [400,400], tex_size => 600, tex_center => 1, scale => 1.1, ); \} $ECENTER END_TEXT Context()->normalStrings;	Main Text: To display the string of plot data $plot, we use the Live3Ddata() routine provided by the macro LiveGraphics3D.pl, which is loaded automatically. After you construct the graph you like, don't forget to take a screen shot of it and make image files such as hyperbolic-paraboloid.png and paraboloid.png that will be used in the pdf hardcopy.
