PHILOSOPHY
- No commercial or freeware 3D engine.
- Simulation written in C++ with OpenGL, GLFW, Glad, GLM, Open Asset Import Library (assimp), libigl, ImGui, OpenAL, NanoVG, stb, Eigen, FFTW3, Pugixml, libnova, Clipper2.
- Real time simulation with high rate of frames per second (target of 120 fps in fullscreen 2560 x 1440).
- The rendering of the 3D scene is optimized to ensure consistency of visual quality between all elements: ocean, ship, sky, clouds, terrain, mist or fog effects.
OCEAN
- Spectral wind wave model, based on Phillips spectrum.
- Dynamic PBR anisotropic BRDF.
- Foam simulation.
- Underwater view.
- Instanced patches defined by LOD settings.
- Host readbacks for in-game physics.
- Spectral analysis.
WIND
- Strength (1 to 30 knots) and direction.
SKY
- Dynamic sky (physical atmosphere) with moving volumetric clouds, godrays and bloom.
- Sun positioned according to date and time (day and night).
- Mist and Fog.
SHIP
- Full motion over 6 degrees of freedom (surge, sway, heave, yaw, pitch, roll).
- Ship motion forces (archimede, gravity, viscous resistance, wave resistance, residual resistance, wind drift, wind rotation, thuster, bow thruster, stern thruster, propellers, rudder).
- Propellers and radars animated.
- Reflection of the ship on the water.
- Wake simulation (Kelvin waves, foam and bubbles).
- Smoke simulated with particles.
- Flag animated.
- Navigation lights.
- Autopilot with Proportional-Integral-Derivative controller.
ENVIRONMENT
- Camera full smooth motion (orbital around the ship, fps, fixed views and free views on board the ship, binoculars).
- 3D sounds (engines, seagulls, horn).
- Terrain (islands).
- Markup (buoys with lights).
- Lighthouses with beamlights
- Only c++ files and shaders are provided with some resource files. Compilation needs the installation of several librairies.
