Real-time water simulation on GPU with OpenGL

CMC MSU, 5 semester bachelor, 2019

Demo video

Build

Required GPU with OpenGL support >=4.3

Linux (Ubuntu) package dependencies: libglfw3, libglfw3-dev

Build with ./compile.sh

Code structure

• ./*.bmp - image sources
• main.cpp, common.cpp - main variables, gui loop
• textured_sphere, textured_wall - underwater objects
• water_surface - rendering of water
• shaders/ - vertex, fragment, compute shaders

Features

• Surface water waves simulation
• Interactive water disturbing
• Reflection of "sky"
• Refraction of light through water, illumination of underwater surfaces
• A ball placed underwater, also affected by refraction
• Utilization of compute shaders for water surface simulation and refracted light on underwater objects

Shortcuts

• Mouse control
• WASD movement
• Right click - disturb water surface
• Q - toggle wireframe water surface
• F1-F4 - teleport to preset scene
