Editing

• All Operations use the Command Pattern, to support Undo/Redo
• Uses Mnemonic/Inner State Pattern for Create/Destroy
• Python Support ??
• Commands bindable to Buttons, MenuItems, Right-Click Menu....

Move,Scale,Rotate

• when Tool is active, show the apropriate gizmo in scene
• gizmo acts on Current Selection (iEditable)
• gizmo gives visual MouseOver feedback
• support snapping

Creation

• CreateFrameComponent : Activates a Create-Mode :
• click(first corner) + drag(2d base) + click(3d)
• gizmo gives visual feedback during creation
• support snapping

Selection

• types/smartpointers for vertex,edge,side
• Selection managed as (named)list of those types
• Selection depends on active "type" (vertex,edge,side,component,group), no mixing
• select gizmo (rectangle)
• Toggle select on intersect or only on complete containment
• manual selection with shift(add) and control(remove)
• when selection from list, and last selection was manually altered, save last manual selection as named
• undo for selection
• group select : when group is already selected, click selects subgroup

Picking

in popup :

• current selection,
• named selection,
• hierarchy list (groups)
• pick-by-click (current mode : vertex,edge,side,component,group)

Tools

• ToolPanel = view, Tool = model(singleton) -> model/view seperation, change-listener
• Tool->CreatePanel()
• Python Support ??
• Tools can "pick" current selection, named selection, groups, or pick-by-click

• Named Selections (depends on current mode (vertex,edge,side,component,group)) + Select/Unselect/Show/Hide/Delete
• Mode Selection (vertex,edge,side,component,group)
• Tool Selection (Select,Move,Scale,Rotate,Extrude,Bevel,SpinExtrude,SpinBevel)
• Snap (Grid,Vertex,Edge,Face)
• AngleSnap (edit+on/off button + buttons for 20 30 40 45 60 90)
• Name+Group / Ungroup
• Hierarchy-List (also for popup)
• Change Parent (opens hierarchy-list popup)
• Later : Change Type (popup : for compatible types, eg titanframe -> steelframe ??)
• Later : Change Side (point,line,3up,3down,square,penta,[x]:popup)

only for top/bottom, autoconvert if top/bottom <= 4

• Later : Toggle select on intersect or only on complete containment
• Later : QuickCut/Slice (component, : DrawLine Gizmo
• Later : Create Adapter : pick operand a,b
• Later : ExtrudeAroundEdge,TurnAroundEdge (pick edge + turn selection)
• Later : SoftSelection (falloff:distance/adjactance,falloff:linear,cubic,curve,falloffdist)
• Later : Dock : move 2 sides together and link them, pick base(not moved) and operand (modifyed)
• Later : Constraints/Links + LockSize (link 2 sides of different components, only move, not scale group)
• Later : Prism-Based Subdivide (height/width)
• Later : Hide/Show Selection/All

Gizmos

• scalable with +/-
• mouseovereffekt, areas : axis,area-between

Click / Drag Handling

• TODO : Research : CEGUI

• Tool/Mode/Gizmo can activate "MouseMode", abort on esc,rightclick

and when another MouseMode is activated

Spawning/ObjectCreation

• MouseMode
• Frame/Cockpit :
  • click on side : extrude/bevel
  • click on empty : create in space/ on grid

Inclusion/Intersection Warning

• not possible for space ships, breaks interior-definition,

and enables cheating (ultra compact, multi-dimensional cargo bays)
