Representation of curves,aight line segments in Chapter 2. Shapes with lines and circular arcs are familiar and easily defined. They are straightforward to produce manually by turning, by numerically controlled (NC) milling machines and so on.

Introduction to surface and solid modelling, in which such objects can be held within a computer system and in this chapter we review some of the current approaches and try to indicate some of the underlying techniques. These are often extensions of ideas that have been discussed in previous chapters.

Nachhaltig erfolgreiches E-Marketings the building up of component shapes out of simpler volumetric forms or primitives. These primitive shapes include such entities as (truncated) cones and rectangular blocks. The general forms of these are predetermined but they possess parameters which the user can define to create the types of shape that are required.

Intersection of curves,em requires the presence of commands that find the intersection of specified geometric entities. The trimming is easily accomplished by redefining an end of each entity to be the calculated point of intersection and then removing the unwanted parts from the display (possibly by redrawing it).
