    • Inspection of Lace Using Machine Vision 

      Norton-Wayne, Len (Blackwell Science Ltd and the Eurographics Association, 1991)

    • Inverse Displacement Mapping 

      Patterson, J.W.; Hoggar, S.G.; Logie, J.R. (Blackwell Science Ltd and the Eurographics Association, 1991)
      Inverse displacement mapping is a variant of displacement mapping which does not actually perturb the geometry of the surface being mapped. It is thus a true texture mapping technique which can be applied during rendering ...

    • A Physically Based Colour Model 

      Oddy, Robert J.; Willis, Philip J. (Blackwell Science Ltd and the Eurographics Association, 1991)
      We propose an intuitively simple way of representing colour which has the additional virtue that, it permits mixing and overlaying of transparent and opaque paints to an arbitrary degree. Our approach is related to the ...

    • Quadtrees, Transforms and Image Coding 

      Martin, R.R.; Anguh, M.M. (Blackwell Science Ltd and the Eurographics Association, 1991)
      Transforms and quadtrees are both methods of representing information in an image in terms of the presence of information at differing length scales. This paper presents a mathematical relationship between these two ...

    • A Survey of Several Root-Finding Methods in the Complex Plane 

      Szyszkowicz, Mieczyslaw (Blackwell Science Ltd and the Eurographics Association, 1991)
      In this paper a few classes of root-finding iterative methods are presented and used in the complex plane to solve the equation z4? 1 = 0. These methods are studied using computer graphics techniques.
