Structures and Hierarchical Modeling
Structure concepts
structure - a named collection of graphic items
(possibly other structures)
openStructure(id)
ie
openStructure(6);
setLinetype(lt);
setPolylineColourIndex(lc);
polyline(n, pts);
closeStruture;
Setting Structure Attributes
Editing structures
-
structure list
-
edit mode
-
inserting structure elements
-
replacing structure elements
-
deleting structure elements
-
labeling structure elements
-
copying elements from one structure to another
note the idea of structures in VTK

Basic modeling concepts
model representations
- symbols (say AND, OR, NOT )
- instances of symbols
- model (assume the wires)
in(1) in(2) AND out
(connections specified to other symbols)
modeling packages
(understand the inter-connections/ relationships
between symbols)

hierarchical models
-
a house is a collection of rooms,
-
a room is a collection of walls,
-
a wall is a collection of ...
-
Local coordinates and modeling transformations
-
rubber stamps have default location,
-
stamped item transformed
to location in structure
-
and so on in the hierarchy
