| $Revision: 1.1.1.1 $
|
| Description:
| This file defines the handle box dragger class.
|
| NOTE TO DEVELOPERS:
| For info about the structure of SoHandleBoxDragger:
| [1] compile: /usr/share/src/Inventor/samples/ivNodeKitStructure
| [2] type: ivNodeKitStructure SoHandleBoxDragger.
| [3] The program prints a diagram of the scene graph and a table with
| information about each part.
|
| The following parts in this dragger are created at construction time.
| 'ResourceName' corresponds to the name of the default geometry for the
| part. The dragger's constructor gets the scene graph for 'ResourceName'
| by querying the global dictionary ( SoDB::getByName("ResourceName"); ).
|
| Resource Name: Part Name:
|
| NOTE: for the translators and extruders,
| numbering refers to a cube-face:
| 1=top,2=bot,3=lft,4=rit,5=fnt,6=bak
|
| handleBoxTranslator1 - translator1
| handleBoxTranslator1Active - translator1Active
| (ditto for translator2-translator6)
|
| handleBoxExtruder1 - extruder1
| handleBoxExtruder1Active - extruder1Active
| (ditto for extruder2-extruder6)
|
|
| NOTE: for the uniform scalers,
| numbers refer to a corner:
| 1=+x+y+z, 2=+x+y-z, 3=+x-y+z,
| 4=+x-y-z, 5=-x+y+z, 6=-x+y-z,
| 7=-x-y+z, 8=-x-y-z
| handleBoxUniform1 - uniform1
| handleBoxUniform1Active - uniform1Active
| (ditto for uniform2-uniform8)
|
| NOTE: for the arrows, numbering refers
| to cube-face they point out from:
| 1=top,2=bot,3=lft,4=rit,5=fnt,6=bak
|
| handleBoxArrow1 - arrow1
| (ditto for arrow2-arrow6)
|
