This is a simple water simulation program.
Inspired by WebGL Water by Evan Wallace: http://madebyevan.com/webgl-water/.
Although the original WebGL Water by Evan Wallace is open-source, I did not use any of it's code and approaches because I can't read js code. Instead, I implemented the simplified wave equation using the double-buffer render pass in the template code. Then I used 2 additional passes for simple water refractions and reflections. These are all good-old methods not involving ray-tracing or any other high-level techniques.
The terrain generation uses siv::PerlinNoise library by Ryo Suzuki.
I did not implement much of the GUIs and all the parameters were hard-coded for a best performance. (But I think we still can modify the parameters in the shaders since the shaders will be re-compiled every time before the program starts)
Expecting some bugs, e.g., the waves sometimes won't fade and the whole surface might blow up eventually.
