Topics:

• remember to log in your Google account. Open the tutorial code by clicking on the link above. Alternatively, in the video we explain how to choose a tutorial from GitHub. After the code is opened, remember to click on the “copy to drive” button
• wikipedia explanation: https://en.wikipedia.org/wiki/Maurer_rose#Explanation
• the code on wikipedia is incomplete. Our tutorial includes a better version (wikipedia code only accepts a few values of ’d'. And our ‘rose’ version 2, which you can find at the end of the tutorial code, can draw also roses with 6, 10, 14, etc. petals)
• in the video above, we code the Maurer rose as a curve (case in which ’d' equals 1)
• …then we code drawing a Maurer rose without the curve: as a group of lines (cases in which ’d' is greater than 1)
• we show how to draw a Maurer rose with both the curve and lines
• we create videos by changing the number of petals and the parameter ’d'
• at the end of the code above, there is a version 2 of the Maurer rose code. It is not explained in the video. It allows for roses with all petal numbers, including 6, 12, 14, however the number of petals in version 2 must be an integer number

Kodindonesia provides a helper library, ‘kicolab’, to make it easier to start having fun in Colab:

• the manual shows examples of almost all the features about how to use the canvas to draw and to display drawings
• there is also an advanced example on how to use kicolab with openCV. An upcoming video tutorial will show more openCV examples
• the manual above also shows how to create your own videos

• Python
• Colab
