  • Domain Extension of Isothetic Polyhedra with Minimal CSG Representation 

    Arinyo, Robert Juan (Blackwell Science Ltd and the Eurographics Association, 1995)
    We consider the problem of converting boundary representations of isothetic polyhedra into constructive solid geometry (CSG) representations. The CSG representation is a boolean formula based on the half-spaces supporting ...

  • Bresenham's Line Generation Algorithm with Built-in Clipping 

    Kuzmin, Yevgeny P. (Blackwell Science Ltd and the Eurographics Association, 1995)
    One of the most important operations in many graphical systems is the generation of a line segment. This process consists of two stages: clipping and drawing. These two stages are separated in current graphical applications. ...

  • Inverse Displacement Mapping in the General Case 

    Logie, J. R.; Patterson, J. W. (Blackwell Science Ltd and the Eurographics Association, 1995)
    Inverse Displacement Mapping is a form of displacement mapping which allows the ray tracing of displacement mapped surfaces. The technique performs all calculations in the inverse (parametric) space of the surface thus ...
