About project

This is one of the projects created during "Computer Graphics 2" course, specialty CAD/CAM systems design of degree in Computer Science and Information Systems at Warsaw University of Technology.

Project features:

• The duck moves along segments of B-spline.
• Custom procedurally generated billboards are used to represent point lights on the scene.
• The scene is lit using the Phong model.
• Compute shaders are used for water simulation and respective computation of water surface normal vectors.
• Snell's window effect when looking from under the water.

Navigation

LMB - camera rotation

RMB - camera zoom in/out

Compilation

The project is written in C++ (OpenGL) using CMake as a build system. It has two configuration CMake options:

Option	Description
DUCK_EMBEDDED_SHADERS	If ON shader code will be embedded into a resulting app's binary. If OFF shader code will be read from shaders directory, so a binary has to be run from repository root directory.
DUCK_SHOW_DEBUG_CONSOLE	If ON - beside app's window - a debug console will be shown on app start up. If OFF only app's window will be shown.

Windows

All subsequent commands should be called from Windows Power Shell.

git clone --recurse-submodules -j8 https://github.com/Tolisz/ComputerGraphics_Duck.git
cd ComputerGraphics_Duck
cmake -S . -B build -DDUCK_EMBEDDED_SHADERS=ON -DDUCK_SHOW_DEBUG_CONSOLE=OFF
cmake --build build --config Release

.\build\Release\duck.exe

Linux

All subsequent commands should be called from terminal. Compilation was checked using g++ (version 11.4.0) and clang++ (version 14.0.0) compilers.

git clone --recurse-submodules -j8 https://github.com/Tolisz/ComputerGraphics_Duck.git
cd ComputerGraphics_Duck
cmake -S . -B build -DDUCK_EMBEDDED_SHADERS=ON -DDUCK_SHOW_DEBUG_CONSOLE=OFF
cmake --build build --config Release -j 26

./build/duck
