Draw a Forest of Random Tree Objects with Python OpenCV - Classes and OOP Practice for Beginners

Video Description

In this tutorial, we will practice the principles of Object-Oriented Programming and draw a forest of unique tree objects. We will first create a Tree class and then we will replicate it in different locations, sizes and colours. We will also include a very large degree of randomness in our code, so that each time our program runs - a brand new forest with brand new trees is created! 🤩🤩🤩 🛑🤚 HAVE YOU WATCHED ✋🛑 ******************************************* 1.
