CAVIS (Cellular Automaton View in SFML)

CAVIS provides a simple way of displaying your cellular automaton. It comes in two flavors: Window and Widget. Use the Widget to display the automaton on your own projects. Alternatively use the Window and get started fast!

cmake ..
make install # As root

Usage

• Implement a cellular automaton using the provided interface (cellular_automaton.h).
• Pass it as a std::unique_ptr to the Cavis or Window constructor.

#include <CAVIS/window.h>
#include "predator_and_prey.h"

int main() {

    // HD aspect ratio = 16:9
    unsigned height = 100;
    unsigned width = height * 16 / 9;
    unsigned cell_size = 4;

    Window window(
        std::make_unique<PredatorAndPrey>(), 
        width, 
        height, 
        cell_size, 
        "Predator & Prey"
    );

    window.run();

    return 0;
