Output Primitives and Geometric Transformations
You learnt how some basic geometric objects such as line segments, circles, ellipses and other curves are processed for plotting on a display unit. In most of the graphics packages you will find that polygons are also used as standard output primitives. Filled polygons with single solid color (or other alternatives for filling the interior) are provided as shape primitives.
What are the different types of parallel projections? The parallel projections are basically divided into two types, depending on the relation among the direction of projectio
Geometric tables - Polygon Tables 1) Vertex table: Keep vertices' coordinates values in the object. 2) Edge table: Keep pointers back in to the vertex table for identif
Two Modes of Operation of Tablets Tablets typically sustain two modes of operation as: 1) Digitizer Mode: creates a one-for-one connection between screen and tablet.
Boundary Fill Algorithm Boundary fill algorithm is suitable when the boundary has single color while flood fill algorithm is more suitable for filling regions which are defined
