¿Que es COLLADA? COLLADA (COLLAborative Design Activity), formato del archivo de intercambio para modelos 3D.
COLLADA es un Schema XML standard para modelos 3D.actualmente es manejado por el Grupo Khronos, quien se encarga de los estándares OpenGL, OpenGL ES.
El formato fue creado por Sony Computer Entertainment por Rémi Artaud y Mark C. Barnes.este fue liberado al Grupo Kronos y usa la licencia SCEA Shared Source License.
en Marzo del 2011 el Grupo Khronos lanza un Test suite para poder importar y exportar al formato Collada archivo.dae
el sitio oficial de Collada es http://collada.org

¿Como lo puedo usar en IOS ?
Scene Kit (Objective-C) - An Objective-C framework introduced in OS X 10.8 Mountain Lion that allows reading, high-level manipulation and display of COLLADA scenes.
Scene Kit is a 3D-rendering Objective-C framework that combines a high-performance rendering engine with a high-level, descriptive API. Scene Kit supports the import, manipulation, and rendering of 3D assets without requiring the exact steps to render a scene the way OpenGL does.
At a GlanceWith Scene Kit you can:
• Import COLLADA 3D objects and build scenes composed by cameras, lights, and meshes. • Manipulate the bounding volumes, geometry, and materials used in a scene. • Load 3D content using an interexchange format supported by all major content creations apps (using DAE (digital
asset exchange) files.• Add live interaction with loaded 3D content. • Integrate your app with other OS X technologies such as Core Animation and GLKit to add overlays and textures for
the 3D objects in your scenes.• Use Xcode to preview, inspect, and adjust DAE files for Scene Kit to help integrate them into your app.

Class / Protocol Description
SCNView & SCNSceneRenderer A view that displays (or renders) SceneKit content and a protocol that defines important methods for use with SceneKit views.
SCNScene The container for all SceneKit content. You load a scene from a file created in a 3D authoring tool or create one programmatically, then display it in a view.
SCNNode The basic building block of a scene. A hierarchy of nodes defines the logical structure of a scene, and you provide visible content by attaching geometries, lights, and cameras to nodes.
SCNGeometry A three-dimensional object that can be attached to a node. A geometry (sometimes called a model or mesh) defines only the form or shape for a visible object. To define the surface appearance of the object you attach materials to it.
SCNMaterial A reusable definition of surface appearance properties for an object. Materials specify how a surface is colored or textured and how it responds to lights in the scene.
SCNLight A light source that can be attached to a node, providing shading in the rendered scene.
SCNCamera A virtual camera that can be attached to a node, providing a point of view for rendering a scene.

Ejemplo de archivos
En la carpeta art.scnassets
Se encuentran los archivos .dae de colada y los .png de las texturas de los modelos.
