Procedural terrain generation using native C code + Unity
This repository is an example showing how to use native C code (DLL) from Unity to generate Perlin‐noise based terrain.
It includes two implementations:
- Native C implementation (compiled into a DLL and called from Unity)
- Pure C# implementation inside Unity
It is not production‑ready; the code is somewhat hacky, especially the Unity side. It’s mainly for learning how to interoperate Unity with native C code.
/Native_Code/ ← C source + build project for the native DLL
/Perlin-Noise-Terrain-Generator/ ← Unity project / C# scripts
.vscode/ ← Editor configuration

- Only tested in the Unity Editor on Windows/ 64‑bit .
- Unity integration of Perlin Noise 3D is a bit hacky. So, don't count on the results.
- DLL build / native code may require specific platform settings; may need adaptation if you move to other platforms.
- To understand interop between managed (.NET / C#) and unmanaged/native (C) code
- To see the performance trade‑offs: speed vs ease of development, memory copying, data marshaling
- As a learning tool or proof‑of‑concept
