C++/OpenGL tool for realistic ocean wave rendering. Originally developed as a winter 2020 term project for CPSC591 @ University of Calgary.

based on my other repo...

• cpp-xplatform - (C++17 cross-platform template repository using CMake + Git Submodules.) - CC0-1.0 licensed.
• and building off some parts of the code from my CPSC589 project... cage-tool.

• GCC (libstdc++) 7
• Clang (libc++) 6
• MSVC (MSVC Standard Library) 19.14 (VS 2017 15.7)
• Apple Clang 10.0.0

• note: all C++17 core language features are supported by these compilers, but some library features are unsupported.

easiest (preferred) method:

git clone --recursive https://github.com/TexelBox/wave-tool.git

or (if you did a normal clone already (first two lines below)...)

git clone https://github.com/TexelBox/wave-tool.git
cd wave-tool/
git submodule update --init --recursive

• note: the enforced generators by the scripts are "Visual Studio 2017"/"Visual Studio 2017 Win64" and "Unix Makefiles" for their respective platforms. I won't be testing this repository with any other generator (use cmake --help for a list), but anybody can try using cmake manually to see if another generator works.
• note: cd scripts before running any scripts (i.e. must run scripts from scripts/ directory).

• double-click or use your favourite terminal to run

dev-build-all.bat

• note: you may have to run ./dev-build-all.bat or .\dev-build-all.bat instead (depending on your shell).

• use your favourite terminal to run

./dev-build-all.sh

• note: if for some reason the script is non-executable, then run the script through an interpreter (only bash is tested, but you can try another like sh).

bash dev-build-all.sh

or add executable permissions and then run

chmod +x dev-build-all.sh
./dev-build-all.sh

• for best performance, double-click/run wave-tool.exe in either x86/Release (32-bit) or x64/Release (64-bit).

• for best performance, double-click/run wave-tool in build/Release.

• if using VS2017, open either x86/wave-tool.sln or x64/wave-tool.sln and click the green arrow (you can also change the build config with the drop-down - use Debug when you need the debugger and Release when testing for performance).

make
./wave-tool
