Frustum Culling // Terrain Rendering episode #9

Описание: In this video we implement Frustum Culling in order to avoid rendering patches which are outside the camera's field of view.

🔥 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!).
