 GUI  Making the GUI, communicating with user  Pat  GUI Model Relations  Keep the greater project design in mind at all times and keep it working and the design logical  Vijay  Model  Processing expression. We started off with Josh’s Arithmetica and was therefore a fitting role for him  Josh http://www.foolingnobody.com/images/roles_01.jpg

 Use Josh’s Arithmetica code  Cleaner Parser class  Greater ease to extend  Treats parenthesis, comma better  Creates “Grouper” objects  Take parts from Pat and Vijay’s code  Operator functionality / hierarchy  Josh’s code design had more strengths than Pat and Vijay’s  Therefore, we used it (it = Josh’s Arithmetica code)

 Arithmetica is the basis for the model  Read function input  Parse input/ create expression object  Tokens of Operator, Operand, Grouper  Evaluate Expression at each pixel  Action performed by View  Evaluate method of expression returns RGB Color  Easy to extend (see below)  Add additional functions  Functions are basis for all picture renderings

 Certain input methods will not be accepted to simplify coding implementation  Function separated by Return or newline characters  Shown in Demo  Grouper is classified separately from Operator  Justified because Groupers are different from Operators  Makes error-checking more tedious/ difficult

 File Menu  Open  Save  Buttons  Random  Evaluate  Breed  Text Fields  Current Expression  Enter Expression

 File Menu  Save  Save Current image to file  Load  Load image from file, display image expression  Buttons  Random  Display a random expression in the View  Evaluate  Evaluate a single expression inputted  Breed  Merge two expressions inputted in the left/right boxes

 Current progress  Shown during demonstration http://www.cartoonstock.com/newscartoons/cartoonists/mbc/lowres/mbcn638l.jpg

 Watch!!!!

 Finish the project?  Implement error checking  Clean up Model-View Interaction  Finish GUI  Implement extensions http://www.schroders.com/StaticFiles/Image%20Library/homepage/sif-completion-361x383.jpg http://www.abcbuilding.com.au/wp-content/practical-completion.jpg

 Allow users to view multiple images at once  Separate windows, tabs, or a grid of thumbnails)  Allow users to "debug" expressions  Use mouse to display point and evaluated values  Allow users to save a history of old expressions http://hairstyleschat.com/wp-content/uploads/2009/04/how-to-use-hair-extensions.jpg
