turtle-conics 0.1.0

Creating different conic sections

 Creating Conic Sections using Python Turtle

We have created a Python package 'turtle-conics'.Using this package, we can draw different curves like Ellipse ,Parabola, Hyperbola in Python Turtle in any orientation as you like. *THIS IS THE FIRST VERSION OF THE PACKAGE. * Check out the Source code for the Package in my Github Repository

FEATURES

-Simple function to create any of the above mentioned curves by importing functions from all_curves module specifying the arguments. -Can be used inside Looping structures to create different patterns.

Package Description

The 'turtle-conics' package consists of module 'all_curves' with 3 functions to draw Ellipse, Parabola and Hyperbola.

--ELLIPSE

We can draw 2 types of ellipse:- - Major axis along X axis (a>b) - Major axis along Y axis (b>a)

def ellipse(a, b, h= None, k= None, angle= None, angle_unit= None)

• a:-It is the half-length of major axis of ellipse if (a>b) else half-length of minor axis when(b>a).
• b:-It is the half-length of major axis of ellipse if (b>a) else half-length of minor axis when (a>b).
• h,k:-(Optional) For drawing ellipses with center (h,k).By default both are zero. -angle(Optional) By providing the angle we can draw elliptical arcs upto that specific angle.By default angle is set to 360 degrees. -angle_unit(Optional) The argument for angle can be in degrees or radians. By default it is set to 'd'. NOTE:- For angle_units specify argument as 'd' or 'r'

--Parabola

We can draw 4 types of parabola:- -Parabola along +ve X axis -Parabola along -ve X axis -Parabola along +ve Y axis -Parabola along -ve Y axis

def parabola(a, t, orientation, h=None, k=None)

• a:- It is the distance from the origin to the focus of parabola.
• t:- It is a parameter of a parabola.Used to define the curvature of parabola.Value of t should be greater than zero. -orientation:-Takes argument as 'x' or 'y' for drawing parabola along X axis or Y axis.
• h,k:-(Optional) For drawing parabola with vertex at (h,k).By default both are zero. -**NOTE:- For drawing Parabola along Negative Axes pass Negative value for 'a' **.

--Hyperbola

We can draw 2 types of Hyperbola:- -Transverse axis ie hyperbola along X axis(a>b) -Transverse axis ie hyperbola along Y axis(b>a)

def hyperbola(a, b, h=None, k=None) -a :-It represents the distance from the vertex to the center of hyperbola when (a>b) else it represents the distance perpendicular to the transverse axis from the vertex to the asymptote line when (b>a).

• b:-It represents the distance from the vertex to the center of hyperbola when (b>a) else it represents the distance perpendicular to the transverse axis from the vertex to the asymptote line when (a>b).
• h,k:-(Optional) For drawing hyperbola with center (h,k).By default both are zero.
• We can also make a Rectangular Hyperbola by giving equal values to 'a' and 'b'. -NOTE:-For drawing Hyperbola along X axis enter values for 'a' and 'b' such that (a>b) else for drawing hyperbola along Y axis put (b>a) .

--CARDIOID

We can draw 4 types of cardioid:- -Axis along X-axis #Cardioid along +ve X axis #Cardioid along -ve X axis

-Axis along Y-axis #Cardioid along +ve Y axis #Cardioid along -ve Y axis

def cardioid(a, orientation, h=None, k=None, angle=None, angle_unit=None)

• a:-It defines the size of the cardioid. -orientation:-Takes argument as 'x' or 'y' for drawing cardioid along X axis or Y axis.
• h,k:-(Optional) For drawing cardioid whose starting point is (h,k). By default both are zero. -angle(Optional) By providing the angle we can draw arcs of the cardioid upto that specific angle.By default angle is set to 360 degrees. -angle_unit(Optional) The argument for angle can be in degrees or radians. By default it is set to 'd'. NOTE:- For angle_units specify argument as 'd' or 'r'. **For drawing Cardioid along Negative Axes pass Negative value for 'a' **.
