WrapAround
The WrapAround shader grabs a snapshot of the entire 360-degree environment surrounding the camera. This snapshot can be useful in a variety of ways: as a reflectivity map, spherically projected onto a dome as an environment map, etc.
Procedure
Position the camera.
In modeler create a flat polygon, this will be the surface onto which effect will be rendered. The animator needs to position the camera so that it is directly faceing the flat polygon so that no unwanted distortion occurs. Also make sure that the normals of the polygon are faceing the camera, or make the surface two sided.
In surface settings for the polygin, select WrapAround as the shader.
Render.
