This video is an introduction to the Geometry Shader in OpenGL. We use the Geometry Shader to develop a billboarding demo where a texture is always presented in front of the camera.

🔥 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!).
