FluidSimulation is a 2D fluid simulation project that demonstrates Smoothed Particle Hydrodynamics (SPH) techniques. The project is written in C++ and utilizes SFML for rendering along with ImGui for real-time controls and debugging.

This project is designed to simulate fluid behavior using particle-based methods (SPH). It includes:

• Particle Dynamics: Simulation of fluid flow using particles.
• Efficient Rendering: Batch rendering of particles using an SFML Vertex Array for high performance.
• Spatial Partitioning: Implementation of a uniform grid (spatial map) for rapid neighbor searches, which is key for SPH calculations.
• Real-Time Controls: Integration with ImGui to adjust simulation parameters on the fly.

• SPH Simulation: Utilizes SPH techniques to calculate density, pressure, and forces between particles.
• Batch Rendering: Renders large numbers of particles efficiently.
• Spatial Partitioning: Uses a uniform grid to accelerate neighbor search operations.
• Modular Design: The simulation, rendering, and utility functions are organized into separate classes to facilitate future enhancements.

• C++17 or later
• SFML (version 3.0 or higher)
• ImGui (version 1.91.9b or higher)
• ImGui-SFML for UI integration, version 3.0 or higher
• CMake for building the project

1. Clone the repository.
2. Create a build directory and run CMake to configure the project.
3. Build the project using your preferred build system (e.g., via CLion or the command line).

Example using the command line:

mkdir build
cd build
cmake ..
make
./FluidSimulation
