This project is based on my Bachelor thesis, in which I developed a wind simulation module as an extension to an existing C++ physics engine. The goal was to simulate realistic, dynamic wind behavior and integrate it into an already established engine architecture.
The implementation was originally created as part of a university repository. This repository serves as a structured showcase of my contribution, including explanations of design decisions and key implementation aspects.
- Integration of a wind simulation model into an existing physics engine
- Real-time computation of wind forces affecting objects in the simulation
- Modular and extensible C++ design
- Focus on performance and efficient update cycles
- Physically inspired behavior using procedural noise
- Designed the wind simulation model
- Implemented the system in C++
- Integrated the module into the engine’s update loop
- Worked with an existing codebase and adapted to its architecture
- Evaluated different approaches for realistic and stable behavior
The system was implemented as an extension module within the existing physics engine. It interacts with core engine components such as:
- object update loop
- force application system
- simulation timestep handling
The design emphasizes:
- separation of concerns
- minimal coupling with existing systems
- reusability of components
The wind behavior is generated using procedural techniques to achieve natural-looking motion. Key aspects include:
- time-dependent variation of wind strength and direction
- smooth transitions using noise functions
- configurable parameters for intensity and turbulence
- Efficient per-frame updates
- Avoidance of unnecessary recomputation
- Lightweight integration into the physics pipeline
- C++
- Existing Physics Engine (C++ based)
- Procedural Noise Techniques

This repository is intended as a showcase of my work and contributions. It highlights the core concepts, implementation approach, and integration into an existing system rather than providing a full standalone engine.
