| The major contribution of this thesis is the adaptation and implementation of two recently published high quality, space-variant, constant-time filtering techniques, the 'Elliptically Weighted Average Filter' by Greene and Heckbert and the 'NIL Constant-Time Space-Variant Filter' by Fournier and Fiume, into the author's NuGraf-3d scanline rendering system.;A second significant contribution of this thesis is the development of stable surface parameterizations for projective and affine mappings. The solutions presented are applicable both to texture mapping and to other applications. The thesis also provides a thorough overview of all phases of the texture mapping process, including a tutorial of 1D and 2D filtering theory, and a detailed review of existing filtering techniques.
