This is part 1 of a multi-part series on grass rendering. We’ll start by figuring out how realistic grass should look like, and how herbage can be modeled with the tools we have at our disposal in real-time 3D graphics. Then, we’ll look at how to implement different methods of grass rendering in Godot. However, most of the tutorial will not be Godot-specific aside from some node names and syntax. But before getting into any implementation details, we must first understand what grass even looks l...
