Realistic Grass Rendering using DirectX 11 and a geometry-shader based approach.

Realistic Grass Rendering - DirectX 11

Realistic grass simulation using the geometry shader to render millions of grass blades simultaneously.

The project is using SharpDX with DirectX 11 settings. A video is available on YouTube: https://youtu.be/jxnacUBaG7c

Installation

• Visual Studio 2013
• Building the project will automatically download all dependencies thanks to NuGet.

Resources

I mainly used and combined ideas from the following papers (sorted by importance):

• Edward Lee: Real-Time Grass (Master Thesis)
• Kevin Boulanger: Rendering Grass in Real Time with Dynamic Lighting (PhD Thesis)
• Markus R. Tillmann: Procedural Rendering of Geometry-Based Grass in Real-Time (Bachelor Thesis)

However, there are a few more notable articles, mostly describing alternative ways to render grass:

• GPU Gems: Rendering Countless Blades of Waving Grass
• Outerra: Procedural Grass Rendering
