       Demo of agent based model on GPU with CUDA and OpenGL
       (Windows/Linux)  Agent instances on GPU memory Uses SSBO for
       instanced objects (with GLSL 450 shaders) CUDA OpenGL interops
       Renders with GLFW3 window manager Dynamic camera views in OpenGL
       (pan,zoom with mouse) Libraries installed using vcpkg

         | Hi, thank you for your interest. Agent based model is a term
         | refers to an interaction between multiple object (called agent)
         | with its own property. The triangle is one agent in this case
         | and in this example it moves along a random trajectory (just
         | like people in a crowd). Each triangle also has its own color
         | of its population so agents in the same population will have
         | the same color.
