The Endless Grid
In this video we learn how to create an infinite grid using OpenGL. It is based on an article from the '3D Graphics Rendering Cookbook' (see link below).
🔥 See the list of the books that I'm using as background information for my tutorials: https://ogldev.org/books.html. I highly recommend them for learning more about OpenGL and Vulkan. These are affiliate links so if you use them to buy any of the books the price is the same for you and I will get a small commission (thank-you!).
