Monte Carlo Simulation of Pi with SDL2

This project demonstrates the Monte Carlo method for estimating the value of Pi using SDL2 for graphical visualization. It simulates random points within a square and checks how many fall within a circle, providing a graphical view of the simulation as it progresses.

Features

• Monte Carlo Simulation: Estimates Pi by generating random points within a square and counting how many fall inside a circle.
• Real-Time Visualization: Uses SDL2 to render the points and show the real-time Pi approximation.
• Pause/Resume: You can pause the simulation with the spacebar and resume it by pressing it again.

Requirements

• SDL2: Graphics library used for rendering.
• SDL2_ttf: For displaying text on the screen.
• g++: Compiler for building the project.
• Font: Make sure the required font is available (DejaVuSans-Bold.ttf is used).

Building the Project

To build the project, use the provided build.sh script. It compiles the source code with the necessary libraries.

Usage

1. Run the build script:

   ./build.sh simPi.cpp <output>

2. Execute the program by running (if no argument is provided, the default value is 10,000 point):

   ./<output> <number_of_points>
