Bachelor Thesis

Title: Simulation of Movement of a Ship Floating on Water Surface

Abstract

The thesis task was to create a simple ship simulator, that will model a unit floating on a water surface. To accomplish that, water has been interpreted as a finite grid of vertices with different heights. The ship's hull on the other hand, is simulated with usage of three dimensional grid, that based on its cells immersion level with respect to the heightfield, calculates both: a point and a force of buoyancy. At each frame PhysX library, supplied with all the information, computes the ship transformations in a current step of the simulation. The application allows one to tweak all parameters via its extensive graphical user interface and freely move around the scene. What is more, the ship can be controlled by applying different forces at the front of its hull.

Technology:

• C++
• OpenGL
• PhysX

Building

Note: Currently only Windows platform is supported. Sources have been checked on Windows 10 64bit. Please let me know about any issues.

• In repository main folder call following commands:

  mkdir [project directory]
  cd [project directory]
  cmake ..
  

• Open

  [repository main folder]\[project directory]\BachelorThesis.sln
  

• Change Debug to Release and click Build->Build Soulution.

Setup.exe

It is is possible to create setup executable for the application from the repository sources. Please first build the app and then make use of the following steps:

• Install Inno Setup Compiler
• Go to

  [repository main folder]\[project directory]\Release\win_installer
  

• Open and compile

  [repository main folder]\[project directory]\Release\win_installer\win_installer.iss
  

• Setup executable resides in:

  [repository main folder]\[project directory]\Release\win_installer\Output
  

Installation

To properly install the application, download DybiszBachelorThesisSetup.exe from the latest release and simply use it. Alternative way is building it from scratch from the repository sources.

Usage

Depending on the installation process, one should either run:

[repository main folder]\[project directory]\Release\bachelor_water.exe 

or

[installation directory]\bachelor_water.exe

Window with the simulation should pop up along with a console.

Any configuration can be done via modifying:

[repository main folder]\[project directory]\Release\config.ini

or

[installation directory]\config.ini

(depending on the previous steps). Some of the entries (e.g. resolution, fullscreen or number of quads) are not mutable during runtime, hence the file is the only way to set them.
