In this video we will go over the details of getting basic texture mapping working in OpenGL using C++.

🔥 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!).
