Presentation Transcript

  1. Alice

  2. Demos • Interactive • Eat the Bunny (Lee) • Movie • Halloween Greeting Card

  3. Alice.org • Visual programming environment • Storytelling/movies • Game programming

  4. Alice.org • Makes it easy to do 3D movies and interactive animations • Fun and intuitive programming model • you can see the objects you are programming • Highly visual programming environment • don't have to memorize syntax • Why the name Alice? • she's the central character in Lewis Carroll’s classic children's story Alice in Wonderland

  5. Alice • FREE! http://www.alice.org • Load and run a world • Names ending in .a2w are Alice programs • a2w is an abbreviation for alice 2world • Two kinds of animations • Movie: passive user watches the animation • Interactive: active user interacts with keyboard and mouse • Chapter 1http://faculty.harrisburgu.net/~paris/cis120/alice_reading_1.pdf • Chapter 2http://faculty.harrisburgu.net/~paris/cis120/alice_reading_2.pdf

  6. Basic Concepts in Alice • Virtual world: an animation is implemented in Alice as a virtual world • Object: basic entity in Alice that has features. • Dimensions and directions: each object in Alice has • Dimensions: height, width, depth • Directions: up, down, forward, back, left, right • Center of an object: at the center of mass • Objects can be retrieved from • Local gallery, or • Web gallery

  7. Basic Concepts in Alice (cont) • Distance: distance between two objects is measured from the centers • Location: in a 3-D space, described by a triplet (x,y,z). The center of the ground is at (0,0,0) • Animation: you develop a set of commands (methods) for each of the object in your world to interact with each other, creating an effect of animation

  8. Objects

  9. Objects • objects • In Alice, an object is (usually) visible and it • has a name • may have sub-parts that are also objects • has properties such as width, height, color, location • can perform methods (actions) on command • has functions that allow programs to obtain information about the object

  10. Objects • Three dimensions: height, width, depth • Six degrees of freedom (types of movement) • 3 moving: • forward/back • left/right • up/down • 3 turning: • roll: sideways • around forward back axis • pitch: up/down • yaw: left/right

  11. Objects • Center • Of mass: • On ground: • Where it is held

  12. Storyboard and Scenes Scene Number: Sketch Description: Sound: Text:

  13. Alice • Tutorial • Start with Tutorial 1 • Shows you how to use the program

  14. A Whole New World • File > New World • Templates tab • double click desired template

  15. Add Objects • Click on “Add Objects” pick from gallery

  16. Object Parts • Objects may be composed of parts • they are accessible through the object browser (upper left)

  17. Save your world • File > Save World • Saves as .a2w file • Save FREQUENTLY • Animation is processor intensive, can crash

  18. Storytelling Alice: Say, think Walk to, Walk offscreen Walk Sit On Lie on Kneel Fall Down Stand Up Straighten Look at Look Turn to face, Turn away from Turn Touch Keep Touching Generic Alice: Move Turn Roll Resize Play Sound Move to Move toward, Move away from Orient to Turn to Face, point at Set point of view to Set Pose Stand up Move at speed, turn at speed, roll at speed Constrain to face, Constrain to point at What you can do… Caitlin Kelleher

  19. Alice Techniques • The mouse is used to approximately position objects in the scene • Camera navigation is used to set the camera point of view • Object drop-down menu used for many things including • resizing objects • more precisely position objects in the scene • Quad view is used to position one object relative to another object • 2-D text:http://faculty.harrisburgu.net/~paris/cis120/alice_tips.pdf

  20. Alice is “real coding” • Alice CodeJava Code

  21. The Future: Alice v3.0 • Been in development for almost a year; will release in 2008. • Driven by Caitlin Kelleher’s findings about storytelling • make movies (or videogames) • Real Java • Alice v3.0 is a Java IDE, based on eclipse • will see real Java (if you choose) • Drag & Drop or type -> it’s up to you! • Insanely high production values: as good as real video games • We are developing a textbook along with the system • Just as we did with Alice v2.0 • Wanda Dann, Steve Cooper, Randy Pausch and Don Slater • EA has given us $300,000* and permission to use the characters and animations from “The SimsTM 2” in Alice v3.0

  22. The First Public Demo ofAlice v3.0 with theSimsTM! This scene was rendered in Alice v3.0
