Terrain-Generation

Author: Andrew Gyakobo

A procedural terrain generation project built with C++ and modern OpenGL. This repository implements noise-based algorithms and real-time rendering techniques to create realistic and visually stunning terrains. The project leverages ImGUI for an interactive user interface, GLEW for OpenGL extensions, and GLSL for shader-based rendering.

Features

• Noise-Based Terrain: Implements Perlin or other procedural noise algorithms for smooth, natural terrains.
• Real-Time Rendering: Powered by OpenGL and GLSL shaders for efficient 3D visualizations.
• Interactive Controls: Modify terrain parameters dynamically using the ImGUI interface.
• Customizable Settings: Adjust resolution, noise parameters, and rendering modes in real-time.
• Camera Controls: Navigate the terrain using a built-in camera system.

Prerequisites

Ensure your system has the following installed:

• A C++ compiler (e.g., GCC, Clang, or MSVC)
• OpenGL 3.3+ compatible GPU and drivers
• GLEW: OpenGL Extension Wrangler
• GLFW: For creating windows and handling input
• ImGUI: For user interface
• GLM: For mathematics (optional, but recommended)

Getting Started

1. Clone the Repository

git clone https://github.com/Gyakobo/Terrain-Generation.git
cd Terrain-Generation

2. Build the Project

For Linux users you can run the program with the following:

sudo g++ -std=c++11 main.cpp src/*.cpp src/imgui/* -o main -lGLU -lglfw3 -lX11 -lXxf86vm -lXrandr -lpthread -lXi -ldl -lXinerama -lXcursor -lGL -lGLEW 

# If the previous command didn't work out then please run the following where I specifically manually added all the necessary IMGUI dependencies
sudo g++ -std=c++11 main.cpp src/*.cpp src/imgui/imgui.cpp src/imgui/imgui_impl_glfw_gl3.cpp src/imgui/imgui_demo.cpp src/imgui/imgui_draw.cpp -o main -lGLU -lglfw3 -lX11 -lXxf86vm -lXrandr -lpthread -lXi -ldl -lXinerama -lXcursor -lGL -lGLEW 

sudo ./main

Alternatively, please just run the build.sh after you go it executable permissions: sudo chmod +x build.sh

For Windows users you should just:

mkdir build && cd build
cmake ..
make

Methodology

So this should be the simple usage criteria:

• Modify Terrain Parameters: Use the ImGUI panel to adjust noise parameters (scale, octaves, persistence) or change rendering options.

• Camera Controls:

  • W/A/S/D: Move forward/left/backward/right.
  • Mouse Drag: Rotate the camera.
  • Scroll: Zoom in/out.

• Export Screenshots: Save a snapshot of the current view (if implemented).

Future Features

• Add support for advanced noise algorithms like Simplex or Worley noise
• Implement texture mapping for more detailed terrains
• Add water rendering with reflection/refraction effects
• Simulate dynamic lighting and shadows
• Support terrain export as heightmaps or 3D models
• Add more textures of maybed even a height-map
• Generate texture wrappers(images) based on the features of the shape
