Perspective Projection - Part 1 // OpenGL Tutorial #11

GameBoost is the only place you need to purchase various premium gaming services, including accounts, boosting, coaching, and more! https://gameboost.sjv.io/4G1G20 In this video I'm going to explain and implement perspective projection in OpenGL. This transformation is core in making your 3D game actually look like it has a third dimension. It makes objects that are further away from the camera appear smaller while closer objects appear larger. This video is part one and deals mainly with the projection of the XY coordinates. In the next video we will handle the Z component and the aspect ratio. Back face culling is explained in    • From Dot To Triangle  // OpenGL Tutorial #3   Make sure to watch all the previous tutorials in the "OpenGL For Beginners" playlist at    • All OpenGL Tutorials   Please visit https://ogldev.org to see more of my tutorials on modern OpenGL. ** Link to source: https://github.com/emeiri/ogldev/blob...
