Lighting // Terrain Rendering episode #5
In this video we study two methods to light a terrain - the standard Diffuse Lighting and the novel technique of Slope Lighting.
🔥 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!).
This video is based on "Focus on 3D Terrain Programming" by Trenk Polack: https://www.amazon.com/Focus-Terrain-....
Slope Lighting is based on an article by Charlie Van Noland: https://archive.gamedev.net/archive/r...
