SoUnits — node that scales to convert units of length

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.

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

SoSFEnumunits
          Defines the current unit.
