Matcher File/View

The matcher's File/View tool is of a familiar design (seeStereoTool and MonoTool).

Pick

The matcher's File/View tool controls a pair of logicalTv's called model and scene to display model and scene primitives respectively. A host of "pick" facilities are available for each through the model and scene pick menus. The 3D geometrical descriptions comprising model and scene are displayed with arrow heads indicating directionality. All pick facilities work on the these 3D geometrical descriptions.

Model

null

choose

select geometrical primitives and delete remainder.

delete

delete selected geometrical primitives.

direct

select directedness of chosen primitives (straight lines only) in accordance with the end closest to the pointer.

pairs

show the features with which the most recently selected primitive shares pair wise table relations (possibly all). In the current implementation the pick calls a repaint so the display is transient (3 seconds).

matches

show the features (in the otherTv device) with which the most recently selected feature can match according to the conservative matching criteria used on focus features.

focus

select the most recently picked feature to be the current focus feature.

group

select the list of picked features to be the feature group associated with the current focus feature. In addition the mouse mode of model and scene can be used to add matches between features (only straight features at present). Simply pick scene and model descriptions alternately (in any order) using the left hand mouse button (the match is made against the most recent selection made in the otherTv device). Note that matches are direction specific and the mouse is able to select the direction of features when constructing matches.

Scene

as model (above) but without ``focus'' & ``group''.

File

Files with the following extensions:

Model

.poly

Scene

.poly

Cliches Old

.ffgnn

Cliches New

.ffg

input/output.

Reading in a model clears the current cliche list and hence cliches must be read after models.

Directory Name.

part of the pathname to use when reading/writing files.

Base Name.

part of the pathname to use when reading/writing files.
