Calling Sequence

Parameters

Description

Examples

Calling Sequence

randpoint(w, x, y, z)

randpoint(w, obj, ...)

Parameters

w

-

the name of a random point

x

-

range

y

-

range

z

-

range

obj

-

line, plane, or sphere

Description

• 

The routine geom3d[randpoint](w, x, y, z) returns a point with the x-coordinate, y-coordinate, and z-coordinate in the interval specified by x, y, and z respectively.

• 

When the second argument is a line, a plane, or a sphere, geom3d[randpoint] returns a point on that geometric object.

• 

If the object obj is a line, and the third optional argument which is a range is given, w is a point of the line segment such that the parameter in the parametric equation of the line lies in that range.

• 

If the object obj is a sphere, and the optional third, fourth arguments which are ranges are given, w is in general the point with the x-coordinate and y-coordinate restricted inside these ranges.
