plots[changecoords] - plotting coordinate changes

Calling Sequence

changecoords(p, coord)

Parameters

p

-

plot data structure

coord

-

new coordinate system

Description

• 

The changecoords function transforms a plot structure to one that uses a new coordinate system.

• 

The input p must be a two or three dimensional plot data structure, while coord must be one of the accepted set of coordinate types available. At present these include:

  

In three dimensions - bipolarcylindrical, bispherical, cardioidal, cardioidcylindrical, casscylindrical, confocalellip, confocalparab, conical, cylindrical, ellcylindrical, ellipsoidal, hypercylindrical, invcasscylindrical, invellcylindrical, invoblspheroidal, invprospheroidal, logcoshcylindrical, logcylindrical, maxwellcylindrical, oblatespheroidal, paraboloidal, paraboloidal2, paracylindrical, prolatespheroidal, rosecylindrical, sixsphere, spherical, tangentcylindrical, tangentsphere, and toroidal.

  

In two dimensions - bipolar, cardioid, cassinian, elliptic, hyperbolic, invcassinian, invelliptic, logarithmic, logcosh, maxwell, parabolic, polar, rose, and tangent.

• 

The conversions from the various coordinate systems to Cartesian coordinates can be found in the coords help page.

• 

The result of a call to changecoords is a PLOT or PLOT3D data structure containing information to render the plot. The user may assign the data structure to a variable, save it in a file, then read it back in for redisplay.  For more information about plot data structures, see plot/structure or plot3d/structure.

• 

There are other functions available to transform plot data structures. A number of these are in the plottools package and are listed on the plottools help page.  The plots[display] function can also be used to transform plots.

• 

The command with(plots,changecoords) allows the use of the abbreviated form of this command.

Examples

withplots:

p:=plotsinx,x,x=0..2π:

changecoordsp,polar

p:=plot3d1.3xsiny,x,y,x=1..2π,y=0..π:

changecoordsp,spherical

changecoordsp,paraboloidal

changecoordsp,conical2,3

p:=plot3dx+y,x,y,x=π..π,y=π..π:

changecoordsp,bipolarcylindrical
