OpenGL Procedural Terrain Generator

Simple procedural terrain generator written in C++ using OpenGL. The application generates a grid of vertices of certain size that are displaced by procedurally generated height map of accumulated Perlin noise values.

Features

Version 1.1

Height-based terrain - grid of displaced vertices
Procedural height map - Fractal noise of Perlin noise
Cube map - sky box arround the terrain
FPS camera - allows to fly-over the terrain
Shading based on Phong shading model, along with height-based blending
- blending between height regions that are textured and / or single colored
Interactive GUI - set various terrain parameters, add / remove regions
Falloff map - allows generation of islands
Profiling - visualizes execution time of certain functions
