DESCRIPTION
This node removes nonuniform 3D scaling from the current transformation matrix when traversed by an action. It is used by draggers such as the SoTrackballDragger that need to stay uniformly scaled no matter where they are located in the scene graph. The magnitude of the new scale is determined by the current transformation matrix and the sizing field. This node does not change the translation or rotation in the matrix.
FIELDS
c
}
c
}
sizing
Determines which of the algorithms enumerated by the type Sizing will be used to select the new scale when the x,y, and z scales are not equal.

c
}
recalcAlways
If recalcAlways is TRUE, this node calculates its unsquishing matrix every time it is traversed. If FALSE, then this only occurs during the first traversal folllowing a call to recalc().
METHODS
c
}
c
}
SoAntiSquish()
Creates an anti-squish node with default settings.
c
}
c
}
getClassTypeId()
Returns type identifier for this class.
c
}
c
}
recalc()
Sets a flag so that the next time the node is traversed, it will recalculate its unsquishing matrix.
ACTION BEHAVIOR
SoGLRenderAction, SoCallbackAction, SoGetBoundingBoxAction, SoGetMatrixAction, SoRayPickAction
Appends the current transformation with a new matrix to create an unsquished result.
