Uboats!

Description

Uboats puts the fun into CFD with the following steps:

  1. Take a 2D Fluid Simulation
  2. Put small uboats into the flow
  3. Add torpedos
  4. ...
  5. Profit!

Screenshots

Complete and numerically sound, highly optimized fluid simulation using a Finite Difference Discretization with a Semi-Lagrange Advection scheme.

Uboats! features 1-4 player split screen modes.

Watch how the explosions make craters in the fully destructible terrain, creates a shower of particles and a pressure wave.

Build instructions

Dependencies

Uboats! has been developed on Arch Linux using various GCC versions. Building has been tested on Ubuntu and Windows.

Uboats! requires the following libraries to build:

  • GLM
  • SDL2
  • GLEW

Then simply type makein the terminal.

Hardware requirements

Uboats! requires an OpenGL4+ capable GPU. Performance has been optimized for an Intel HD620 integrated GPU and an i7-8550U quad core CPU. Any modern IGP and quad core CPU should work.

Please report errors and problems with building the game and running on other graphics drivers!
