In this video we begin a mini series on implementing Skeletal Animation in OpenGL using Assimp. We will review the basic concepts and implement a simple utility to parse the data structures of Assimp in order to access the relevant parts for Skeletal Animation. In future videos we will develop this utility further and incorporate its logic into our OpenGL application. Learn how to load and render models using Assimp: The complete mini-series on Skeletal Animation: Part 1: Part 2: Part 3: Part 4: Part 5: 🔥 See the list of the books that I'm using as background information for my tutorials: 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!).
