Convert IRR to STL

The IRR (Irrlicht 3D Scene) file extension is associated with the Irrlicht Engine, an open-source 3D graphics engine written in C++. IRR files store scene graphs in XML format, containing elements such as particle systems, animators, and materials, which Irrlicht references to render game environments. These files may also include links to IRRMESH files for defining scene nodes. The Irrlicht Engine, first released in 2003, gained popularity for its lightweight design and cross-platform compatibility, making it a preferred choice for independent game developers and graphics programmers.

STL, short for Stereolithography, is a widely used file format in the realm of 3D printing and computer-aided design (CAD). Introduced by 3D Systems in 1987, it represents the surfaces of a 3D object through a collection of triangles, facilitating precise and efficient model creation. Utilized across various industries such as engineering, manufacturing, and healthcare, STL files are critical for prototyping and producing complex geometries. Their simplicity and compatibility with numerous software applications have cemented STL's importance in the digital fabrication landscape.
