The following sections give an introduction to the 2D animation system Proof 5. Proof 5 (P5) is the latest generation of a system first published in 1990 by Wolverine Software.
The basic objects or primitives of Proof Animation will be introduced and explained using an example. The Draw-Mode of Proof Animation is used for designing interactively a Layout consisting of Lines, Arcs Text and Pictures. Please note relation between graphical and textual representations of the graphical primitives in a Layout.
The moving objects are instances of user defined object classes. They are designed in the Class-Mode and are components of the Layout file. After object classes have been defined, any number of objects of any class can be created, positioned, moved and destroyed.
In the Run-Mode an Animation Time or Clock starts to run. It runs with a constant, but selectable speed. The Animation Trace file (ATF) contains animation commands, that are processed in Run-Mode. They are concerned with animation time, the objects, their state changes and motions.
Objects can move freely or on Paths. Paths are defined in the Path-Mode and saved in the Layout file. Paths can have several attributes. The motion of objects on Paths is controlled by animation trace commands. The object motion can be directional or undirectional
Messages, Bars and Plots can be seen as predefined object classes. Just like user defined object classes any number of Messages, Bars and Plots can be created and specified. This is done in the Draw-Mode. The updating of these objects is triggered by ATF-commands. Updating means the assignment of current values during the animation.
In all Modes the View button is available. By calling it, the camera can be panned, you can zoom in and out, select predefined Views and subdivide the screen into Windows. A View can get a name, can be saved and called by this name.
