Smooth Particle Hydrodynamic Simulator with OpenGL based rendering & OpenCL based calculation.

1. Install dependencies:

   vcpkg install opencl
   vcpkg install opengl

2. Modify header file if needed. Change:

   #include <CL/cl.hpp>

   into:

   #include <CL/cl2.hpp>

3. By default, the particle color is determined by density. To produce the result in the sample, please change the << particles.cl>> shader file. Change:

    colorVec[i * 4 + 0] = diff < 1 ? 1 : 2 - diff;
    colorVec[i * 4 + 1] = diff < 1 ? diff : 1;
    colorVec[i * 4 + 2] = 0;
    colorVec[i * 4 + 3] = 1;

   into:

   colorVec[i * 4 + 0] = i < 4000;
   colorVec[i * 4 + 1] = 4000 <= i && i < 6000;
   colorVec[i * 4 + 2] = 6000 <= i;
   colorVec[i * 4 + 3] = 1;

4. Run the program in the <<PROJECT_ROOT_DIRECTORY>> (the one contains shader/ folder).

5. It shall produce the following result:

6. IMPORTANT！！！ Press "P" to exit!.
7. The result is rendered in a 3D world. Press WASD to move around. Press R to rise up, F to fall down. Move mouse to look around.
