Shadow Mapping Strikes Back // OpenGL Tutorial #36
In this video we continue our journey with Shadow Mapping and we learn how to use Orthographic Projection in order to implement shadows with a directional light.
🔥 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!).
