Shadow Mapping Unleashed! // OpenGL Tutorial #38
In this video we take a look at five techniques to reduce the effect of several known problems in shadow mapping such as shadow acne, peter panning and more.
🔥 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!).
