CASA Function: ssiPlot

Plots the intersection of two surfaces using hybrid symbolic-numerical method.

Calling Sequence:

• P := ssiPlot(expr1,expr2,vars)
• P := ssiPlot(expr1,expr2,vars,options)

Parameters:

expr1 : polynom

• A polynomial in the three variables listed in vars.

expr2 :

• A polynomial in the three variables listed in vars.

vars : list(name)

• list of variables

options : exprseq

• options to the function

Result:

P : PLOT3D

• a surface-to-surface intersection plot

Description:

• The function plots the intersection of two three-dimensional and implicitly defined surfaces.
• An appropriate range for each variable will be computed automatically. The user does not need to specify the ranges.
• Options are given as equations of the form option=value.
• All options that are available to MAPLE's plotting-functions (plot[options]) are supported.
• Furthermore, the option epsilon=-n. Specifies precision for real root isolation procedures used in the ssiPlot function.
• Finally, the option maxiterate=n specifies the maximum number of extended Newton iterations used in the ssiPlot function.

Examples:

> ssiPlot(x^2+y^2+z^2 -5, x*y*z -1,[x,y,z],color=green);
