Revision History for IWalkways

What needs to be completed

0.0.1-0.0.5

Prehistoric Versions :). Did not keep track of new features.

0.0.6

• New features: - SelectAll - UnselectAll
• Bug fixes: - Box now turns off after cut
• Inroads: - Beginning to understand dubble buffering.... what a pain, though. FIXED V 0.0.7

0.0.7

• Double Buffering Enabled!
• bug fix with selection box
• added some edges to selection box (only edges with a node highlighted) does not yet include edges which are selected by their interior-- (essential to deleting edges without nodes) FIXED V 0.1.7-0.1.8

0.0.8

• Merge feature added (still very buggy- kills all edges when merging ajacent nodes only merges one selected node)
• Changed initial setup of layout- now different start dimentions
• Added different cursors for different drawing modes
• Added function to calc. local cost (buggy- does not consider width of walk
• Buttons carelessly added
• Think about:
• Node editor
• delete edges when they are selected w/o nodes... could be useful FIXED V 0.1.7

0.0.9

0.1.0- Basic Editor Working

• pop up window for the status of a vertex/edge
• this might need multiple threads

0.1.1

• made new graphics
• made new behavior for it and kept it related to vertex

• POOR DESIGN for invisble screenobjects- need to rework FIXED V0.1.6
• need to be able to select individual edges FIXED V0.1.7-V0.1.8

0.1.5

• Major Overhaul of the cost filter- function still an approximation
• Worked on interfacing checkboxes w/ filters- flow checkbox operational
• Started to work on the shadows

• SHORTCOMINGS
• Still no uniform software interface between canvas and graph... FIXED V0.1.?

0.1.6

• Shadows are enabled (gotta work on getting a good map now!)
• slight software architecture changes

• Need to work on sliders for cost perception

0.1.7

• Deletion of individual edges is now possible
• User interface cleaned up a little (sliders are now larger)
• Started on the detour filter-- basic functionality added.

0.1.8

• Worked on the detour filter more... found 3 points for the circle... cacluations might be slightly off for perp. bisector.
• Fixed selecting edges without nodes in editor. this code could be optimized some
• played a little with the user-interface... still needs lots of work.

0.1.9

• Worked extensively with the detour filter.- gemetry mostly working (special cases needed)
• Need to clean up the code for detours
• Changed the select box to be a slightly different color than the selected edges/nodes (so one can more easily identify the box)

0.2.0 TWO FILTERS CRUDELY WORKING

• Worked on detour filter, beginning to work on end nodes
• UI changes
• To do:
• Must Make Detour filter user sizeable- FIXED V 0.2.1
• Must make detour for end node account for all incoming nodes FIXED V 0.2.3

0.2.1

• Detour Filter size user-definable!
• Worked on single node detour- still need to understand how to handle discontinuous function...
• Merge Nodes/Edges Edges/Edges functions needed

0.2.2

• Single node detour mostly working... spent lots of time on it... can take nothing for granted
• cleaned up the UI some...
• Need to get rid of X's when working...FIXED V 0.2.3
• Need to fix bugs in orderings FIXED V 0.2.3

0.2.3

• Fixed detour bugs... made X's more manageable and also fixed ordering problem.
• Must document cases which fail (none so far, but possibly if angle slider is changed).

0.2.4

• Fixed more detour bugs (single node was incorrect before), and also refined the arcs slightly (need real graphics engine)
• Changed slider so hopefully now it will work with UNIX
• added a "complex detour" switch which shows the relationship between the arcs and lines

0.2.5 final submission?

• made map changes- alternatives are commented... would like to work them in as files...probably will have to make due in the long run as just keeping them in memory

0.2.6 final submission???

• made new menu item to load 1 of 2 preset maps (cornell and the generic map)
• changed select box to disable when entering create mode (so that people don't have a box seleceted forever)
• fixed a small bug in the arc size slider... now fully accurate from the start..

Things to complete before leaving Cornell:
