In this video we learn how to convert an Equirectangular Image to a cubemap in OpenGL. The result can then be used for Skybox rendering.

🔥 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!).
