Adinkrahene is the symbol for leadership and charisma. This symbol is reportedly the inspiration for the design of the other symbols. Its simple yet abstract design, consisting of three concentric circles emphasizes the importance of ideas and abstract concepts.
In the last section, I introduced the grid. The grid will allow us create any symbol we want to because we can analyse and replicate the symbol of our choice.
We will draw a grid of 5 pixel squares on the image of the Adinkra symbol of our choice and replicate that on our grid. The squares on our grid are 10 pixels each. The goal of our program would be to create a grid that is two times the size of the original grid.
Drawing the 5 pixel squares on the Adinkrahene symbol will look as shown below:
Analysing the Symbol
The first circle is 8 squares away from the centre of the circle. So multiplying by 5 would give us 40 pixels.
The second circle is 13 pixels away from the centre of the circle. So multiplying by 5 would give us 65 pixels.
The third circle is 18 pixels away from the centre of the circle. So multiplying by 5 would give us 90 pixels.
The outer circle doesn’t touch the edge of the grid. It leaves a space of 1 square. The thickness of the circles are all 10 pixels.
The Plan to Draw the Symbol
To draw the Adinkahene symbol, we have to compensate for scaling up the shape to twice its size.
As a result of this, we shall increase the size of our pen to 20 pixels.
The first circle will have a radius of 80 pixels. We will move the pen to the location (0, -80) and draw a circle of 80 pixels.
The second circle will have a radius of 130 pixels. We will move the pen to the location (0, -130) and draw a circle of 130 pixels.
The third circle will have a radius of 180 pixels. We will move the pen to the location (0, -180) and draw a circle of radius 180 pixels.
Algorithm to Draw the Symbol
The algorithm to draw the Adinkrahene symbol is shown below:
- Lift up the pen
- Increase the pensize to 20 pixels
- Move the turtle to the position (0, -80)
- Place the pen down
- Draw a circle that is 80 pixels in radius
- Lift up the pen
- Move the turtle to the position (0, -130)
- Place the pen down
- Draw a circle that is 130 pixels in radius
- Lift up the pen
- Move the turtle to the position (0, -180)
- Place the pen down
- Draw a circle that is 180 pixels in radius
Using Turtle Graphics
We will use the template.py file and rename it to adinkrahene.py.
The first step in drawing the Adinkrahene symbol is to draw the innermost circle and work our way out.
The first task is to lift up the pen. The code to do this is shown below:
turtle.penup()
Next we will increase our pensize to 20. The code to do this is shown below:
turtle.pensize(20)
The origin of the turtle is at (0, 0). To move the turtle to the position (0, -80), we use the command shown below:
turtle.setposition(0, -80)
At this point, place the pen down and draw a circle of radius 80 pixels. The code to do this is shown below:
turtle.pendown()
turtle.circle(80)
Our Python Turtle window will look like shown below:
Steps 6 to 9 are the steps for drawing the second circle. The code is similar to what you have already seen before and is shown below:
turtle.penup()
turtle.setposition(0, -130)
turtle.pendown()
turtle.circle(130)
When we run the code, our second circle now appears as shown below:
Steps 10 to 13 will draw the third circle. The code to do this is similar to what you have already seen before and is shown below:
turtle.penup()
turtle.setposition(0, -180)
turtle.pendown()
turtle.circle(180)
When you run the code, the image is as shown below:
