Building a GPU-accelerated particle simulation system using C# and OpenGL: a complete practical guide

Part 1: Introduction and environment configuration

1. Introduction: Particle systems are a common feature in many advanced graphics applications, such as games, movies, and simulations. In this article, we will use C# as the main programming language, the OpenGL library to render graphics, and GLSL (OpenGL Shading Language) to write programs that run on the GPU to achieve GPU acceleration of particle simulation.

2. Environment configuration:

2.1 Install the necessary libraries: In order to start our project, we need to download and install the following libraries:

• OpenGL.Net: A library that provides OpenGL bindings for .NET applications.
• OpenTK: A cross-platform C# OpenGL binding library that also provides math and input processing functions.

These libraries can be installed using the NuGet package manager:

Install-Package OpenGL.Net
Install-Package OpenTK

2.2 Set up a basic window: Using OpenTK, we can quickly set up an OpenGL context and window:
