Abstract:

Fixed vantage point simulation requires a wide field of view for the external visual environment. The sky scene, however, is of secondary importance as moving objects in the scene are the areas of interest. It is therefore cost- effective to represent the sky in such cases as a two dimensional surface enclosing the earth. This memorandum derives the perspective transformation necessary to project points from this sphere onto two dimensional viewing screens. Inversion of this transformation is also presented. Keywords Perspective transformation Visual simulation clouds Three dimensional graphics Australia.
