DESCRIPTION
This node defines a uniform 3D scale about the origin relative to the
previously defined units. The default units for all data are meters.
Adding a units node with the value INCHES will have the same effect as
adding an SoScale node with the scaleFactor of (.0254, .0254, .0254). Any
subsequent SoUnits node will take the previous units into account. When
building a composite object out of a bunch of pieces, it would be a good
practice to add an SoUnits node at the beginning of each of the pieces,
under an SoSeparator node, to make sure all the pieces fit together with
the same scale.
FIELDS
SoSFEnum units
Defines the current unit.
FUNCTIONSSoUnits * SoUnitsCreate()
Creates a unit conversion node with default settings.
SoType SoUnitsGetClassTypeId()
Returns type identifier for this class.
Page 2SoUnits(3IV)ACTION BEHAVIOR
SoGLRenderAction, SoCallbackAction, SoGetBoundingBoxAction,
SoRayPickAction
Accumulates the scale that is the ratio of the size from the
previous unit to the current unit into the current transformation.
SoGetMatrixAction
Returns the matrix corresponding to the units scaling.
