Mastering GLSL in TouchDesigner, Lesson 13: Intro to GLSL Simulations (1)

Simulations bring digital systems to life, allowing us to model fluid dynamics, particle interactions, cellular automata, and agent-based behaviors in real time. In this lesson, we break down different simulation paradigms—particle-based, rule-based, and grid-based systems—and explore how GLSL can drive complex, emergent behavior using textures, multiple buffers, and feedback loops.

📌 Key Topics Covered:
✅ Types of simulations – particle-based, rule-based, and differential equations
✅ Using textures to store simulation state (e.g., position, velocity, and color)
✅ Implementing feedback loops for real-time evolution
✅ Managing multiple buffers for scalable, GPU-accelerated simulations

🎨 Exercises & Challenges:
🛠️ Build a simple particle system with position and velocity buffers
🛠️ Implement Conway’s Game of Life in GLSL
🛠️ Create geometric instance patterns using domain manipulation
🛠️ Modify an agent simulation to create a repelling force between particles
