1. Animation and Sound Pertemuan 02 Matakuliah: L0182 / Web & Animation Design Tahun: 2008

2. Bina Nusantara Learning Outcomes Pada akhir pertemuan ini, diharapkan mahasiswa akan mampu : Menunjukkan penggunaan Animasi dan Sound pada Aplikasi Multimedia

3. Bina Nusantara Outline Materi Definition 2D Animation 3D Animation Morphing and Warping Frequency and Amplitude Advantages and Disadvantages of Using Animation and Sound

4. Bina Nusantara Definition Animation is a sequence of frames that, when played in order at sufficient speed, presents a smoothly moving image like a film or video.

5. Bina Nusantara 2D Animation 2D animation is the creation of moving pictures in a two-dimensional environment. This is done by sequencing consecutive images, or "frames", that simulate motion by each image showing the next in a gradual progression of steps. Two types of 2D animation : –Cel animation : based on changes that occur from one frame to the next –Path animation : moves an object along a predetermined path on the screen

6. Bina Nusantara Cel Animation & Path Animation Cel Animation Path Animation

7. Bina Nusantara 3D Animation 3D animation is animating objects that appear in a three-dimensional space. They can be rotated and moved like real objects. The process of creating 3D computer graphics can be sequentially divided into three basic phases : –Modeling : the process of forming the shape of an object –Animation : defining the object’s motion –Rendering : the process of generating an image from a model, by means of computer programs.

8. Bina Nusantara Modeling and Rendering

9. Bina Nusantara Animation Special Effects Morphing : a transformation of images. It is used in many animations and movies to warp a first image into a second image. Warping : the process of digitally manipulating an image such that any shapes portrayed in the image have been significantly distorted.

12. Bina Nusantara Advantages and Disadvantages of Using Animation Animation captures the imagination like no other tool, portraying actions and spatial relationships that are not readily visible in reality or that may not exist at all. Advantages –Attracts and holds attention –Show otherwise invisible actions or physical processes –Increases retention –Allows visualization of imagined concepts, objects and relationship Disadvantages –Requires extensive memory and storage space –Requires special equipment for a quality presentation –2D animation cannot depict actuality like video or photography

13. Bina Nusantara Sound Sound is a rapid vibrations that are transmitted as variations in air pressure. Described in terms of two characteristics : –Frequency (or pitch) –Amplitude distance along wave

14. Bina Nusantara Frequency and Amplitude Frequency –The rate at which sound is measured –Number of cycles per second or Hertz (Hz) –Determines the pitch of the sound as heard by our ears –The higher frequency, the clearer and sharper the sound  the higher pitch of sound Amplitude –Usually measured in decibels (dB) –Sound’s intensity or loudness –The louder the sound, the larger amplitude.

15. Bina Nusantara Calculating The Size of Digital Audio The formula is as follows: The answer will be in bytes Where: –Sampling rate is in Hz –Duration/time is in seconds –Resolution is in bits (1 for 8 bits, 2 for 16 bits) –Number of channels = 1 for mono, 2 for stereo, etc.

16. Bina Nusantara Audio Formats. WAV (Developed by IBM and Microsoft).AU (UNIX).AIFF (Audio Interchange File Format).MP3 (MPEG layer 3).SND (Mac).RA (RealAudio).WMA (Windows Media Audio).VOC (SoundBlaster)

17. Bina Nusantara Software for Creating Audio Adobe Audition Cakewalk Pro Audio

18. Bina Nusantara Advantages and Disadvantages of Using Audio Sound adds life to any multimedia application and plays important role in effective marketing presentations Advantages –Ensure important information is noticed –Add interest –Can communicate more directly than other medi Disadvantages –Easily overused –Requires special equipment for quality production –Not as memorable as visual media
