COLLADA is a standardized XML file format for exchanging 3D digital assets between different software applications in animation, gaming, and visualization.
Acronym standing for 'COLLAborative Design Activity,' created by the Khronos Group in 2004 as an open standard for 3D model interchange.
COLLADA solved a massive problem in 3D graphics—before it, artists couldn't easily move their work between programs like Maya and Blender, wasting hours recreating the same models in different software.
