Geometry Point class Gsoc 14 - gxyd/sympy GitHub Wiki

Point Class(inherits from the entity class):

__new__

It blocks imaginary points and raises an error for points other than 2-D and 3-D

Methods:

Contains methods common to both 2-D and 3-D

x-coordinate

y-coordinate

length

intersection

__add__

__mul__

__div__

__sub__

evalf

Point_2D Class(inherits from the Point class)

__new__

It checks if the point is 2-D then proceeds

Methods:

convert2D to 3D(converts a 2-D point to 3-D point)

Point_3D Class(inherits from the Point class)

__new__

It checks if the point is 3-D then proceeds

Methods:

z-coordinate

are_coplanar

direction_ratios

direction_cosines

Now coming to the methods common to both Point_2D and Point_3D

is_collinear

is_concyclic

mid_point

distance

transform

rotate

These methods are common to both classes but would require a different algorithm to solve. So should i include them individually in their respective classes? or Place it in the Point class like this for example:

def is_collinear(*args):

if any in args is_instance(Point_3D):

implement 3-D algorithm(In this case we have to convert any 2-D points into 3-D)

else:

implement 2-D algorithm
