Optimize Your Meshes! // OpenGL Tutorial #48

In this video we learn how to optimize meshes and models using the Mesh Optimizer tool.

🔥 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!).
