A general formulation for conies and conic arcs for the purpose of computer graphics is given, based on principles and theorems of projective geometry. This approach allows the approximation of these curves by line segments ...

A fast and effective object space method for antialiasing ray-traced pictures is introduced. Traditionally, anti-aliasing has been done using super-sampling. However, this is costly since it requires casting large numbers ...

We present a new macroscopic texture synthesis method based upon a hierarchical macroscopic texture model. Our model allows the composition of various patterns which can be themselves distorted spatially. Such a method is ...

One of the most successful algorithms that brought realism to the world of 3D image generation is Phong shading. It is an algorithm for smooth shading meshes of planar polygons used to represent curved surfaces. The level ...

The Programmer s Hierarchical Interactive Graphics System (PHIGS) is about to become a standard graphics system? which caters for the definition, display and modification of two and three-dimensional graphical data.PHIGS, ...
