In software development, composition is key — so we’re looking forward to presenting three local C++ entities at once: **[Helmut Hlavacs](https://entertain.univie.ac.at/~hlavacs/)**, **Marlene Kasper**, and **Isabella Hölzl** from the University of Vienna.

Inheriting a shared passion for **Entity Component Systems** (ECS), they will guide us through the essentials of this powerful **data structure**, heavily used in **video games**. Discover how this **composition pattern** works, **dynamically clustering data** tied to specific entities. And go even further as they **explore architectural choices** and **optimization strategies** tailored to different use cases.

They will show us

* What Entity Component Systems are
* How to optimize them
* How LLMs can be used to create them
* And finally **VECS**:
The open-source **V**ienna **E**ntity **C**omponent **S**ystem (+ a tool to visualize it’s content).

See you then!

⌚ Doors open at 5:30 PM and the main event starts promptly at 6:30 PM.
**🙏 Please arrive early to ensure a timely start.**

* We appreciate any **voluntary** donations on site.
* We plan to get food after the main event - either by relocating to the pizzeria, or by providing a simple buffet (depending on number of attendees)
