Water on surface

This project is about water flow simulation on terrain

Terrain modeling 🏔

Program gets external file as first parameter that contains terrain map (map/demoX.mod). It is a series of coordinates in 3D. They define a few sparse points through which surface will imperatively go across. It can be either 2, 10 or 20 points for example (not more than 50).

map/demo2: (10000,10000,6000) (15000,10000,100) (15000,15000,4000)

IDW interpolation algorithm is used to represent a surface that goes through those points.

Water modeling 🧊

Height field based water simulation using "pipe model" The water is represented as a set of columns, water surface is described by the height of the columns. Each column connected to 4 neighbors with "virtual pipes". Program gets as an second parameter an external file containing the initial map of water heights (map/waterXXX.mod)

Basics

  • C++11
  • OpenGL 2.1
  • GLSL 1.20

Dependencies

  • glfw 3.3.2
  • glew 2.1.0
  • glm 0.9.9.5
  • sfml 2.5.1
  • boost 1.72.0

Install

git clone https://github.com/gitEllE-if/water_terrain_simulation.git waterSim
cd waterSim
make

I only tested and run this simulation on MacOS (Mojave, HighSierra, Catalina)

Usage

./mod surface_file [water_file]

example: ./mod map/demo1.mod map/water.mod

  • [ENTER] - start
  • [SPACE] - stop
  • [ASDW mouse] - camera control
  • [1] - water [2] - rain [3] - snow
  • [Z] - sound [X] - mute
  • [<] - slow [>] - fast
  • [-] - leak [+] - rise [0] - none
  • [ { arrow] - water leak at the border
  • [ } arrow] - water rise at the border
  • [p] - none water leak/rise at the border
