3.02 Explain basic motion graphic programming. Animation Types

Frame-by-Frame Animation Rapidly displaying images, or frames, in a sequence to create the optical illusion of movement. Digital animation is based on the frame by frame animation process. Example of a ball bouncing. The link opens this URL: http://en.wikipedia.org/wiki/Animation

Frame-by-Frame Animation (Continued) The quality of frame-based animation depends on the frame rate. Frame Rate = Frames per Second  FPS = Smoother Action Teacher Note: Supplemental Activity Just for fun: See if students can guess how many frames per second television uses. TV Quality Video = 30 frames per second Typical Computer Animation = 24 frames per second Minimum = Anything under 12 frames per second will look “jerky” The more frames per second, the smoother the motion appears.

Stop Motion Animation Process of manipulating real-world objects and photographing them one frame at a time. Very popular method with the film industry until computer generated imagery became possible. Now used mainly in clay animation. Example http://en.wikipedia.org/wiki/File:Moving_Penny.gif Teacher Note: Supplemental Activity: An early example of stop motion animation used in film can be found here: http://memory.loc.gov/cgi-bin/query/h?ammem/papr:@field(NUMBER+@band(animp+1592)) It can be viewed in two different formats. It it entitled The Enchanted Drawing.

Morphing Animation The term morphing comes from the word metamorphosis, which is the transformation of one thing into another. The beginning image is inserted. The ending image is inserted. The computer performs the tweening to generate a sequence of images, each of which is slightly different from the one it follows to gradually morph the two objects. For example, a photograph or object might gradually morph into a different photograph or object.

Example of Morphing Beginning Image Ending Image Finished Animation

Path Based Animation Also called vector animation. An object follows a path which is a line, or vector, inserted by the animator. A motion path can include curves, loops, and angles. The computer calculates the correct position of the object as it moves along the path and generates the frames to create the animation. Teacher Note:

Path Based Animation (Continued) Vector graphics or animated gifs can be used to create animations with very small file sizes. The small file sizes make this type of animation very popular on the Web. Many of the banner ads and embedded animations viewed on web sites use this technology because it loads so quickly and is easy to use. Path Based Tweening in Adobe: https://www.youtube.com/watch?v=HOMFMQCiTLo Teacher Note: In the banner, the text is following a motion path. The butterfly is an animated gif following a motion path. The motion path was created using PowerPoint’s custom animation feature (Under the Slide Show Menu). When the Slideshow is running, click on the butterfly to see it follow the motion path. To show the motion path in the slide view, right-click on the butterfly and click Custom Animation. (In Office 2010, to see the motion path, click on the butterfly and then click on the Animations tab.)

Programming or Scripting-Based Animation Requires knowledge of a programming or scripting language. Example: Rollover or Mouseover When the mouse is moved over an image, it changes to a different image so quickly that it looks as if the change has occurred in a single instant. Created by using scripting languages such as Javascript.

Programming or Scripting-Based Animation (Continued) Rollovers are extremely important for navigation buttons on user interface designs. Examples Web pages ■ CBT programs Kiosks ■ CD-ROM Training Games ■ CDs and DVDs.

Use PowerPoint to Create a Frame by Frame Animation Add graphics and text to create an animation using Powerpoint. You will brainstorm an idea of a sequence of events (short story) that can be created using slides. You will create each slide similar to how one would create a flipbook. Once your slides are complete you will set the timing following instructions on the next slide.

PowerPoint Animation (continued) When you are creating your animation, check the movement by pressing the right arrow key. When you are ready to set your timing go to the next step: Rehearse the timings. Click on Slide Show, Rehearse Timings Run through the slide show by pressing the N key or the right arrow. When done, click save to save the timings. Press F5 to present the slide show animation. Save and preview the animation.
