Fluid Simulation

- Purpose: Implements a basic SPH simulation for fluid dynamics using C++ and SFML for rendering.

- Initialization:

  - Initializes particles, screen dimensions, and simulation parameters.

  - Sets up a spatial hashing system for efficient neighbor searches.

  - Positions particles either in a grid pattern or randomly (commented out).

- Simulation Update:

  - Assigns particles to grid cells for optimized neighbor search.

  - Calculates the density and pressure of each particle based on neighbors.

  - Computes the pressure forces acting on particles.

  - Updates particle positions, velocities, and accelerations based on forces and constraints.

- Rendering:

  - Uses SFML to draw particles on the screen.

  - Iterates over particles to set positions and colors, then renders them as points.

- Density and Pressure Calculation:

  - Computes particle density using neighbor distances and a smoothing kernel.

  - Calculates pressure forces between particles and includes viscosity effects.

- Parallel Processing:

  - Utilizes C++17 parallel algorithms to enhance performance.

  - Executes particle updates and calculations in parallel for efficiency.

- Boundary Handling:

  - Ensures particles remain within screen boundaries by reflecting velocities and adjusting positions if they collide with edges.

- Conclusion:

  - Demonstrates fluid simulation through particle interactions and efficient state updates.

  - Optimized for real-time applications using spatial hashing and parallel algorithms.
