a) Polylines are a series of connected line segments that form a continuous path or shape. They are often used in computer graphics and drafting to represent objects or outlines.
b) Quantization error refers to the loss of detail or accuracy when representing continuous values (such as colors or spatial coordinates) with discrete or limited values. This can result in artifacts such as pixelation or banding.
Aliasing error, on the other hand, occurs when a high-frequency signal is sampled or digitized at a rate that is too low to accurately represent the original signal. This can lead to distortion or the appearance of jagged edges in images or graphics.
c) The raster display architecture, also known as a raster scan, is a method of displaying images on a screen. It consists of a grid of pixels, where each pixel represents a small area of the image. The display scans the pixels row by row from top to bottom, left to right, and illuminates them to create the complete image.
b) An Active Edge Table (AET) is a data structure used in polygon rasterization algorithms. It stores information about the edges of a polygon that intersect a given scan line. The AET keeps track of the starting and ending points of each active edge, as well as the slope and other attributes. It is utilized to efficiently determine which pixels on the scan line should be filled in to render the polygon accurately.
c) Motion tweening and shape tweening are two types of tweened animation in Flash.
Motion tweening involves animating objects along a defined path or trajectory. It allows users to create smooth and controlled movement by specifying the starting and ending positions, as well as the duration and easing of the animation.
Shape tweening, on the other hand, involves morphing one shape into another over a specified period of time. It enables the transformation of one graphic or vector shape into another, allowing for visual effects such as stretching, shrinking, or warping.
Both motion tweening and shape tweening provide powerful animation capabilities in Flash, allowing for the creation of dynamic and engaging content.
