Description
SoDragPointDragger is a compound dragger that translates in all three dimensions when dragged with the
mouse.
It is made up of six smaller draggers, which it displays two at a time. Each pair has one plane dragger
and one line dragger. The line dragger is oriented perpendicular to the plane, so together the plane/linepair lets you move through all of 3-space.
DragPoint has a total of three such pairs, oriented along the x, y, and z axes of its local space. You
can cycle through the three pairs by hitting the <Control> key with the cursor over the dragger. (You
need not press the mouse button.)
The line draggers are SoTranslate1Draggers and the plane draggers are SoTranslate2Draggers. So you can
use the <Shift> key to constrain the motion of a plane dragger along one of the two axes within the
plane, as described in the SoTranslate2Draggers man page.
DragPoint adds extra feedback parts to provide a more intuitive idea of where you are placed in three-
space. There are three feedbackplanes and three feedbackaxes; each corresponds to one of the plane or
line draggers, but spans a much greater distance. When you drag along a line, that line's larger feedback
axis is displayed, and remains anchored in space while the dragger slides along it. This helps establish
the motion of the dragger relative to the rest of the scene. Similarly, when you drag within a plane, the
larger (but transparent) feedback plane establishes a ground plane for you to move upon. The location of
the dragger within the plane is pinpointed by two intersecting axes that always cross below the cursor
and extend to the edges of the plane. When you move dragPoint to the edge of the feedback plane (or
line), the feedback will jump to a new location in that direction, so that the dragger never leaves the
feedback behind.
The primary directions of motion are given by the local space of the dragger. Transforms earlier in the
scene will affect the dragger, its children, and the orientation of its directions of motion.
This node has a translation field which always reflects its position in local space. Setting the field
moves the dragger to that point. You can also connect fields of other nodes or engines from this one to
make them follow the dragger's motion.
Although the child draggers each have their own resources defining default part geometries, the dragPoint
dragger overrides these with a new set of resources. It also defines resources for the feedback parts
that it adds. These are detailed in the Dragger Resources section of the online reference page for this
class. You can change the parts in any instance of this dragger using setPart().
You can make your program use different default resources for the parts by copying the file
/usr/share/data/draggerDefaults/dragPointDragger.iv into your own directory, editing the file, and then
setting the environment variable SO_DRAGGER_DIR to be a path to that directory.

Methods
SoDragPointDragger()
Constructor.
voidsetJumpLimit(floatlimit)floatgetJumpLimit()const
Set and get the point at which the feedback axes will jump to a new position. For example, if set to
.1 (the default), the feedback axes will jump when the dragger gets within 10% of the end of the axis.
voidshowNextDraggerSet()
The dragPoint dragger contains three pairs of draggers, each containing a plane dragger and a line
dragger (see the Description above). The dragger starts with the (y-line/xz-plane) pair displayed.
Calling this method will cycle next through the (z-line/xy-plane), then the (x-line/yz-plane).

Returns an SoNodekitCatalog for this class
staticSoTypegetClassTypeId()
Returns type identifier for this class.
