Data dan Teknologi Multimedia Sesi 07 Nofriyadi Nurdam

At the end of this course, the students will be able to:  Show how to use animation on multimedia application.

 Animation Definition  2D Animation  3D Animation  Special Effect Animation  Working with Animation

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

 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

Cel 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 by creating the broad contours and structure of 3-D objects and scenes ◦ Animation : defining the object’s motion ◦ Rendering : the process of generating an image from a model by giving objects attributes such as color, surface textures, and amounts of transparency, by means of computer programs.

 Morphing ◦ blending together two images into a series of images  Warping ◦ distorts a single image  Virtual Reality ◦ creates an environment that surrounds the user so that he or she becomes part of the experience

 Animated text ◦ using the HTML command causes text to flash on and off  Animated gif ◦ using a software program to create a series of gif files such as GIF Builder  Director movie ◦ animation played using Shockwave plug-in  3D environments ◦ a computer language used to create 3D images

 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 relationships  Disadvantages ◦ Requires extensive memory and storage space ◦ Requires special equipment for a quality presentation ◦ 2D animation cannot depict actuality like video or photography
