COLLADA (COLLAborative Design Activity) is an XML-based 3D interchange format maintained by the Khronos Group — the same organisation behind OpenGL, Vulkan, and glTF. It was designed to be the universal translator between 3D content creation tools, and for a while it was the best option available.
The format stores geometry, materials, shaders, animations, physics, kinematics, and scene hierarchy in human-readable XML. It supports polygonal meshes, splines, NURBS, skinning, morph targets, and multi-pass rendering effects. The XML structure makes it inspectable and debuggable, but also makes files large and slow to parse — a 10 MB binary mesh becomes a 100 MB XML document.
COLLADA was widely adopted in the late 2000s, particularly in game engines (PlayStation used it as an intermediate format) and scientific visualisation. It's since been largely superseded by glTF for real-time applications and USD for VFX pipelines, but COLLADA files still circulate in older asset libraries and academic tools.
