Overview

This project is a Procedural Terrain Generator implemented in C++ and OpenGL. It showcases various advanced rendering techniques, including Perlin noise-based terrain generation, normal mapping, water rendering, and a skybox for realistic visuals. The project is ideal for those interested in learning about computer graphics, procedural content generation, and modern OpenGL practices.

Features

• Procedural Terrain Generation: Uses Perlin noise to generate realistic terrain with adjustable parameters like octaves, persistence, and frequency.
• Normal Mapping: Adds fine details to the terrain surface without increasing the mesh complexity. [In Progress]
• Water Rendering: Implements a reflective and refractive water surface with wave animations. [In Progress]
• Skybox: Surrounds the scene with a skybox for a fully immersive environment. [In Progress]
• Basic Lighting: Incorporates Phong lighting for ambient, diffuse, and specular reflections.
• Camera Control: An Arcball camera system allows for smooth panning, rotation, and zoom around the terrain.

Getting Started

Prerequisites

• C++ Compiler: Ensure you have a modern C++ compiler installed (GCC, Clang, or MSVC).
• CMake: Required to build the project.
• GLFW: For window management and OpenGL context creation.
• GLAD: For loading OpenGL functions.
• stb_image: For loading image files (e.g., textures).

Instatllation

1. Clone the repository

git clone https://github.com/pkunjam/procedural-terrain-generator.git
cd procedural-terrain-generator 

2. Build the project

mkdir build
cd build
cmake ..
make

3. Run the Executable

./ProceduralTerrain

Usage

Camera Controls:

• Left Mouse Button: Rotate the camera around the terrain.
• Right Mouse Button: Pan the camera.
• Scroll Wheel: Zoom in and out.

Terrain Parameters: Adjust the terrain parameters (octaves, persistence, etc.) directly in the main.cpp file to see how different settings affect the terrain generation.
