Unity: Design Procedural Surfaces with Noise Functions

Course Overview

This intermediate-to-advanced course guides learners through the structured development of procedural surface systems in Unity using noise-based methods. Through six focused modules, participants will explore dimensional noise functions, gradient masks, resolution control, derivative computation, and flow visualization using particle systems and scripting. Beginning with foundational practices in texture generation and noise sampling, learners will construct reusable components, apply multi-octave layering, and modify terrain using displacement techniques. As the course progresses, they will extract and use directional derivatives to simulate realistic surface behavior such as erosion or flow. Emphasis is placed on dynamically creating and visualizing directional data through smooth gradients, 3D particles, and flow scripts. Throughout the course, learners will apply, construct, differentiate, validate, and develop noise-driven systems aligned with real-time feedback principles and visual continuity. By the end, they will have built a fully operational procedural surface and flow system that can be extended across games, simulations, or generative art.
