In this case for height, but check the console log when you run it. When you use variables, the same thing happens if you use an undefined variable. A common mistake is when you forget the value and it does not look the way you intended. The first two cylinders in the code above make no sense because they have no height. So as you can see OpenCV has a ton of material you can use to create your own machine learning models that can use OpenCV and know the difference between an apple and an orange! And hey guess what? You have learned a new skill! That’s even cooler right? As a thank you for coming with me on this fantastic journey I have included BONUS OpenCV Material!! Nothing is better than having a bonus!! It’s like an extra present under the tree! This website will help you dive even deeper into what OpenCV is and what you can do with it! You’ll be able to master the open source library in Python in no time using this website! Maybe even a niche for your Python Freelancing? (Did I just give you a clue?) Enjoy and again thanks for joining me.Cylinder ( r1 = 20, r2 = 5, h = 40, center = true ) He has clear explanations and graphics with his code.
