In this video we learn how to implement indirect rendering in OpenGL using glMultiDrawElementsIndirect. This is part of a short subseries on the AZDO (Approaching Zero Driver Overhead) technique.

🔥 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!).
