Reflex.Gloss.Scene

Reflex.Gloss.Scene A simple scene graph implementation rendered using gloss. Contains functionality for picking and transformations. Implements interfaces for MonadSwitch (see reflex-transformers) and MonadTime (see reflex-animations) for switching, and animation support respectively.

data Scene t a

Scene Monad, passes down the scene graph a SceneNode, passes back up the scene graph renderings (Behavior t Picture) Implements MonadSwitch and MonadTime abstractions.
