  • An Algorithm for Perspective Viewing of Objects Represented by Octrees 

    Aref, Walid G.; Samet, Hanan (Blackwell Science Ltd and the Eurographics Association, 1995)
    A new algorithm is presented for viewing three-dimensional objects, represented by an octree, from an arbitrary location. The algorithm generates aperspective view of the objects while eliminating hidden surfaces. The ...
  • Isometric Piecewise Polynomial Curves 

    Fiume, Eugene (Blackwell Science Ltd and the Eurographics Association, 1995)
    The main preoccupations of research in computer-aided geometric design have been on shape-specification techniques for polynomial curves and surfaces, and on the continuity between segments or patches. When modelling with ...
  • Image Warping Using Few Anchor Points and Radial Functions 

    Arad, Nur; Reisfeld, Daniel (Blackwell Science Ltd and the Eurographics Association, 1995)
    Transformations based on radial basis junctions have proven to be a powerful tool in image warping. In the present work we decompose these transformations into linear and radial terms, and show examples where such a ...
  • Symbolic and Numeric Computation in Curve Interrogation 

    Elber, Gershon (Blackwell Science Ltd and the Eurographics Association, 1995)
    The control of shape of curves is of great importance in computer aided geometric design. Determination of planar curves convexity, the detection of infection points, coincident regions, and self intersection points, the ...
  • Efficient Parallel Gouraud Shading and Linear Interpolation over Triangles 

    Narayanaswami, Chandrasekhar (Blackwell Science Ltd and the Eurographics Association, 1995)
    A parallel raster algorithm to draw Gouraud shaded triangles is presented. At the heart of the algorithm is a new constrained parallel edge-traversal technique. This parallel traversal represents an increased level of ...
  • Line Clipping Using Semi-Homogeneous Coordinates 

    Nielsen, Hans Peter (Blackwell Science Ltd and the Eurographics Association, 1995)
    The dual intersection test is described. It is a new method for deciding whether a line intersects a window. The concept of semi-homogeneous coordinates is introduced. It allows us to define line segments in projective ...
