C++ Playground

Personal project where I like to play around with C++ and create interesting graphic visuals.

Content

Dots

An in between of particle/ant simulation. It uses SIMD optimizations to allow for a large number of dots. I can run 1,500,000 dots at 60fps on my machine.

Fun fact: Multithreading the simulation makes it slower. My best guess as to why this is, is cache misses.

Feel free to play around with the settings. I always like to increase the Max Speed.

Controls:

• Left click to attract dots.
• Right click to repel dots.

Watch on YouTube: (Sorry for the youtube compression)

Game of Life

Everyone knows this right?

It uses your whole screen to simulate the game of life. You can change the speed by changing the FPS value.

Maze

A simple maze generator using the recursive backtracking algorithm. IT again uses your whole screen. if Keep longest path is enabled, it will show the longest/hardest path to solve the maze.

Controls:

• Click anywhere on the screen, This will be the starting point of the maze.
• Lower the Steps per frame to see the generation process.

Wolfram

An implementation of the Wolfram cellular automaton. You can change the rule by changing the Rule value.

Check this page to see cool patterns you can make.

Verlet

Circle physics simulation that tries to simulate water.

Feel free to play around with the settings.

Settings:

• Spawn count: how may circles to spawn. When clicking the spawn button.
• Spawn size: the size of the circles. Dont put it below 0.5 or it might take some time calcualte/
• Circle Constrain: toggle this to make the particles stay in a circle.
• Draw Grid bool: a debug grid to see in which cell the particles are.

Controls:

• Left click to attract particles.
• Right click to repel particles.

Circles

A sine wave circle visualization.

Drawing

A circle that keeps getting divided into smaller circles.

Controls:

• Left click on circle to divide it.
• Scroll to zoom in/out.
• Z to scroll in.

How to run

• Download the project and open the .sln file in Visual Studio.
• Run the voxpopuli project with Release on x64.

Starting point for this project is the Voxpopuli made by my teacher Jacco Bikker.
