The Blender.Scene.Render submodule.

Scene.Render
============

This module provides access to B{Scene Rendering Contexts} in Blender.

Example::

  from Blender.Scene import Render
  
  scn = Scene.GetCurrent()
  context = scn.getRenderingContext()
  
  Render.EnableDispWin()
  context.extensions = True

  context.renderAnim()
  
  context.imageType = Render.TARGA
  context.fps = 15
  context.sFrame = 15
