In this video we will study the differences between the fixed function pipeline and the programmable pipeline. We will get introduced to shaders and how to use them in our applications and games.

🔥 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!).
