A simple OpenGL procedural terrain generator

Terrain Generator

Introduction

A very simple procedural terrain generator, created as a weekend project with C++/OpenGL. Terrains can be updated in real-time or through a configuration file. Afterwards, terrain meshes can be exported to OBJ files.

Features

Current Features

• Procedural terrain generation w/ perlin noise
• Color multiple terrain types by height
• Export mesh to OBJ (no materials)
• Default settings configurable with config file

Future Enhancements

• Textures w/ triplanar mapping
• Chunking w/ LOD
• Normal maps
• PBR shading
• Better controls; e.g., sliders, displaying noise textures

Getting Started

Compilation

1. Clone the repository
2. Generate GLAD loader files
3. Build with CMake

Building

Currently only Linux builds have been tested. You must have the glm and glfw3 packages installed. Configure the project with CMake, and then compile the source:

mkdir build
cd build
cmake ..
make

Configuration

Please see the sample config.txt for examples on how to configure the default terrain settings.
