Interactive Graphs of Parametric Curves in Three Dimensions
This PG code shows how to generate interactive graphs of parametric curves from MathObjects formulas. It uses the Java applet LiveGraphics3D to display the interactive graph.
PG problem file | Explanation |
---|---|
DOCUMENT(); loadMacros( "PGstandard.pl", "MathObjects.pl", "parserVectorUtils.pl", "PGcourse.pl", "LiveGraphicsParametricCurve3D.pl", ); TEXT(beginproblem()); |
Initialization:
We need to include the macros file |
Context("Numeric"); Context()->variables->are(x=>"Real",y=>"Real",z=>"Real",t=>"Real"); $plot = ParametricCurve3D( Fx => Formula("t*cos(t)"), Fy => Formula("t*sin(t)"), Fz => Formula("t"), tvar => "t", tmin => 0, tmax => 10, tsamples => 50, axesframed => 1, xaxislabel => "X", yaxislabel => "Y", zaxislabel => "Z", outputtype => 4, ); |
Setup:
We generate a string of plot data using
Setting |
Context()->texStrings; BEGIN_TEXT \{ Live3Ddata( $plot, image => "spiral.png", size => [400,400], tex_size => 600, tex_center => 1, scale => 1.1, ); \} END_TEXT Context()->normalStrings; |
Main Text:
To display the string of plot data
After you construct the graph you like, don't forget to take a screen shot of it and make an image file such as |
