MPEG-2 : MPEG-2 that is Moving Picture Experts Group format 2 is the standard used through DVD and is of a much higher quality than MPEG- 1. This format gives for 720 x 480 resolutions and along with some less loss of detail over MPEG-1. Though, the file sizes are 3 to 4 times larger than MPEG-1.
A DVD can include many hours of MPEG-2 video, although the cost of the DVD writer is even high. MPEG-2 on a CD is probable, by using a format termed as that SVCD but which can only contain around 20 minutes of video.

Character Generation You know that graphics displays often contain components which are text based. For example graph labels, annotations, descriptions on data flow diagrams,
Explain Three Dimensional Transformations A 3D geometric transformation is utilized extensively in object modelling and rendering. 2D transformations are naturally extended to
Consequently some methods are utilized to handle this huge information and these methods are termed as animation process that are classified as: First Method: In this method,
De Casteljau Algorithm For computation of Bézier curves an iterative algorithm known as de Casteljau algorithm is used. The algorithm uses repeated linear interpolation.
The subsequent are also considered graphics applications as: • Paint Programs: Permit you to create rough freehand drawings. The images are saved as bit maps and can simply be
Linearly interpolate - Modeling and Rendering I 4 = I 1 + t (I 2 - I 1 ); here t = (|y 1 - y 2 |)/(|y 1 - y 2 |) I D = I A + t (I B - I A ); here t = (|AD|)/(|AB|)
Clipping and 3D Primitives This unit introduces you to three important concepts of Computer Graphics. After that discusses the concept of clipping, which means removal of objec
