reflecting PLOT and PLOT3D data structures
Calling Sequence
Parameters
Description
Representation
Examples
reflect(p, pt_2d)
reflect(p, [pt_2d, pt_2d])
reflect(q, pt_3d)
reflect(q, [pt_3d, pt_3d])
reflect(q, [pt_3d, pt_3d, pt_3d])
p
-
PLOT data structure or a 2-D object
q
PLOT3D data structure or a 3-D object
pt_2d
(optional) list of two real numbers specifying a point in 2-D
pt_3d
(optional) list of three real numbers specifying a point in 3-D
The reflect command takes a plot structure or object and produces a new plot structure or object.
In the 2-D case, an object can be reflected with respect to either a given point or a given line.
In the 3-D case, an object can be reflected with respect to a point, a line, or a plane.
The result of a call to reflect is a 2-D or 3-D plot structure or object, which may be displayed with the plots:-display command. You can 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.
Several commands in the plottools package can transform plots. For a list, see the plottools help page. The plots:-changecoords and plots:-display commands can also be used to transform plots.
A point is represented as a list of either two real numbers (2-D) or three real numbers (3-D).
A line is represented as a list of two distinct points.
A plane is represented as a list of three distinct points.
