Pathfinding Visualizer

A tool for visualizing numerous pathfinding algorithms in two dimensions.

This project involves minimal implementations of the popular planning algorithms, including both graph-based and sampling-based planners. We provide an easy-to-use GUI to control the animation process and explore different planner configurations. Current implementation of the project involves four search-based planning algorithms: BFS, DFS, DIJKSTRA and A-Star and two sampling-based planners: RRT and RRT*. The project extensively uses SFML, ImGui and Modern C++ features such as smart pointers, lamda expressions along with multi-threading concepts.

Basic Build Instructions

The project depends on SFML, Dear ImGui and ImGui-SFML. However, you are not required to install external dependencies by yourself. The following build instructions will manage all the necessary external dependencies for you.

1. Clone this repo.
2. Make a build directory in the top level project directory: mkdir build && cd build
3. Compile: cmake .. && make
4. Run it: ./main.
