In this video we learn how to create an infinite grid using OpenGL. It is based on an article from the '3D Graphics Rendering Cookbook' (see link below).

📚 Timecodes 📚
0:00 Intro and background
1:42 Start with two triangles
3:19 Locking the square to the camera
4:23 Output the world space position
4:47 Modulate the position by the grid cell size
6:25 GLSL derivative functions
11:10 Render the vertical lines
12:23 Stabilizing the derivatives
13:47 Improving the aliasing situation
14:35 Level Of Detail
18:50 Cell size per LOD
20:00 Use the correct alpha
20:33 The Opacity Factor
21:30 Outro

🔥 I'm using the following books as background information for my tutorials and I highly recommend them for learning more about OpenGL and Vulkan.
