C# Class FBX.Scene.Scene

A scene is a collection of meshes, lights, cameras, textures and material parameters A mesh is a collection of primitives that are rendered by the renderer's render techniques You can load and save a scene in the Nuaj.Cirrus proprietary format. Scenes can also be imported through 3rd party formats (cf. FBXSceneLoader) then saved into the proprietary format.
