Using Ray Casting To Move 3D Objects // OpenGL Tutorial #32
In this video we continue developing the 3D picking demo into something that allows us to move a selected object using the mouse. We do this using a purely math technique called Ray Casting. This video is part of my OpenGL series but since this technique is math-only you can easily adapt it to other APIs as well.
🔥 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!).
