It uses a small polygon approximation of the surface to solve efficiently the hidden parts detection, and then computes the shading on each polygon in such a way that visual discontinuities between adjacent polygons disappear, thus restoring the apparent smoothness of the surface and increasing greatly the realism of the pictures produced. The smooth shading technique described here has been used to produce a large variety of pictures of which several airplanes, a car, a human face and some mathematical surfaces are included to illustrate the effect of the method.

EULER is a block-structured language, similar to Algol-60 but simplified by omitting type declarations and by altering the way procedures are defined and called. PDP-10 EULER includes features for list and array manipulation, and also for a number of forms of input - output, including graphics.

In this period we focused on ...

A large number of business and application areas depend on the efficiency and availability of search techniques that are capable to process and retrieve heterogeneous and dispersed data. These include: a) the Web, b) mobile devices and applications, c) social networks and social media, and d) enterprise data access and organization. The objective of this document is to provide an overview of the business areas, the research challenges and the socio-economic aspects related to “Search Computing”.
