Convert IRR to OBJ

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.

The OBJ (Object) file extension, related to Wavefront 3D Object, is a standard 3D image format developed by Wavefront Technologies. It is widely used for representing 3D geometry, including the position of vertices, texture coordinates, and normals. OBJ files are versatile and commonly employed in various CAD, 3D printing, and computer graphics applications due to their simplicity and compatibility with numerous 3D modeling programs. Introduced in the 1980s, the OBJ format has become a cornerstone in the industry, facilitating easy exchange and rendering of 3D models across different platforms.
