This work presents two different methods for rendering 3D images from topographic data,
namely autostereograms and anaglyphs. For better surface rendering, B-Spline interpolation is used.
Algorithms for autostereograms and anaglyph generation and mathematics of interpolation are discussed.
Theory and algorithms for generation of tiled textures used in autostereograms are also presented
along with two different methods. Comparative tests between different interpolation qualities are made.
