In this video we are going from rendering a single dot to rendering a full triangle. In addition, we will discuss the issue of face culling.

🔥 I'm using the following books as background information for my tutorials and I highly recommend them for learning more about OpenGL and Vulkan.
These are affiliate links so if you use them to buy the books the price is the same for you and I will get a small commision (thank-you!).
