  1. Introduction to Alice Web Design Section 8-2 Alice is named in honor of Lewis Carroll’s Alice in Wonderland

  2. Alice • A programming tool • 3-D graphics • 3-D models of objects • Animation • Objects can be made to move around the virtual world (a simple video game or simulation implemented in 3-D) • If you want to download Alice at home you can get the latest version from the web: www.alice.org • We are using Alice 2.2 here in class…

  3. Demo: Getting started • Starting Alice • Alice is installed on the C-Drive in a folder called Alice2.3 • Make a shortcut to the program and place it on your desktop • Alice is slow to start! Give it time. • Load and run a world • Octopus (movie) • Skater (interactive)

  4. Kinds of Animations • Two kinds of animations: • Movie • Passive user watches the animation • Interactive • Active user clicks on mouse, types a key on keyboard … • Actions of user are called events

  5. Demo: A new world • Create a new world • File  New • Choose template

  6. Demo: Adding objects

  7. Techniques and Tools • Mouse is used to • approximately position objects in the scene • Camera Navigation is used to • set the camera point of view • Drop-down menu methods are used to • resize objects • more precisely position objects in the scene • Quadview is used to • position one object relative to another object • Allows you to see the object from 4 angles at the same time

  8. Objects • An "object" is • any thing that can be identified as unique from other things • How is an object unique? • has a name • has properties: • width, height, color, location • can perform actions (methods): • associated actions it can perform • tasks it can carry out

  9. Object Parts • Objects may be composed of parts

  10. 3 Dimensions, 6 Directions • A 3D object has • 3 dimensions • height, width, depth • 6 degrees of freedom (directions of movement)

  11. Center of an object • At the center of mass • Where it stands on the ground • Where it is held

  12. peter Person paul mary spike Dogs scottie fluffy Class • Objects are categorized into classes • Each object is an instance of the class. • All objects in a class have similar propertiesand generally can perform the same tasks.

  13. Galleries • Classes (3D models) are found in the galleries • Local gallery • Web gallery

  14. Demo: Saving a world • Writing and testing an animation is an intense load on the computing system – a crash can occur. • Best solution: • save your world every 5 minutes • (Or at least every 15 minutes) • also save to a backup

  15. Quick Demo • Lunar Lander…

  16. Rest of Today • Read Chapter 1 from the homework section of the Hancock Web Site • Section 1, Introduction to Alice • Section 2, Alice Concepts • Tips & Techniques 1, Special Effects • You need to read – I will not teach everything about Alice! I will teach programming techniques. • Try out Alice on your PC • Add Objects – See if you can get them to move (or parts of them to move!) • Finish your flowcharts!
