Deprecated: Graphing a Parametric Surface in 3D

Click to enlarge

This PG code shows how to make an interactive graph of a parametric surface that is displayed using the LiveGraphics3D Java applet. It is deprecated because Java is no longer universally supported on all web browsers and platforms.

DOCUMENT(); loadMacros( "PGstandard.pl", "MathObjects.pl", "LiveGraphicsParametricSurface3D.pl", ); TEXT(beginproblem());	Initialization: We need to include the macros file LiveGraphicsParametricSurface3D.pl.
Context("Numeric"); Context()->variables->are(x=>"Real",y=>"Real",z=>"Real",u=>"Real",v=>"Real"); $plot = ParametricSurface3D( Fx => Formula("3*cos(u)*sin(v)"), Fy => Formula("3*sin(u)*sin(v)"), Fz => Formula("3*cos(v)"), uvar => 'u', # theta vvar => 'v', # phi umin => 0, umax => 2*pi, vmin => 0, vmax => pi, usamples => 15, vsamples => 15, axesframed => 1, xaxislabel => "X", yaxislabel => "Y", zaxislabel => "Z", mesh => 0, outputtype => 4, );	Setup:
Context()->texStrings; BEGIN_TEXT \{ Live3Ddata( $plot, image => "sphere.png", size => [400,400], tex_size => 600, tex_center => 1, scale => 1.1, ); \} END_TEXT Context()->normalStrings;	Main Text: We generate a string of plot data using ParametricSurface3D(). Setting outputtype to something other than 4 will require you to read the source code of LiveGraphicsParametricSurface3D.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.
