Procedural Terrain

Description

An infinite procedural terrain, done in C++ with OpenGL. Developed in the context of the course CS-341 Introduction to Computer Graphics at École polytechinque fédérale de Lausanne (EPFL).

Here you can find a short video demo of the project.

Getting Started

You should have at least OpenGL 4.1 installed on your computer. Then all needed libraries are included in the external folder.

To build and run the project execute the following commands:

mkdir build
cd build
cmake ..
make
cd project
./project

Features

Terrain

Infinite generation
Ridged multifractal perlin noise
Tessellation shaders for level of detail rendering
Distance fog

Texturing

Distance and normal based blend
Mimap textures

Sky

Cubemap texture
Day and night cycle

Water

Normal mapping for wave simulation
Sky and terrain reflection
Simple distorsion

Controls

The project is provided with a simple GUI done using the imgui library. It allows to tweak parameters and changing camera mode between the six available, which are described here below.

Custom

Use W A S D keys to move around the terrain, drag with the mouse to change the view.

Flythrough

Use W and S to move forward and backwards, A S Q Eto move rotate the camera respectively left, right, up and down. When in flythrough mode all camera movements have an inertial behaviour.

FPS

The commands are the same as for the Flythrough camera, but in this camera mode you are always on the terrain level.

Prerecorded Bezier

This camera mode follows a prerecorded Bezier path. You can increase/decrease the camera speed pressing W/S.

Record Bezier

Move the camera as in Custom mode, press R to record a Bezier control point.

Bezier

After recording a Bezier path in the Record Bezier mode, this camera follows it. Again you can increase/decrease the camera speed pressing W/S.
