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 is rotation? A 2-D rotation is completed by repositioning the coordinates with a circular path, in the x-y plane by making an angle with the axes. The transformation is g
Uniform B - spline curve: When the spacing between Knot values is constant, the resulting curve is called a uniform B- spline. Blending function for B- spline curves are defined b
What is meant by scan code? When a key is pressed on the keyboard, the keyboard controller places a code bear to the key pressed into a part of the memory known as the keyboard
What is view distance? The view plane normal vector is a directed line segment from the view plane to the view reference point. The length of this directed line segment is ref
