DESCRIPTION
     SoPackedColor is similar to SoBaseColor in that it sets the diffuse color
     component of the current material. However, it also changes the
     transparency component. The color and transparency information is packed
     into unsigned 32-bit integers: 0xrrggbbaa, where aa represents the alpha
     (0x00 = fully transparent, 0xff = opaque), and rr, gg, and bb represent
     the red, blue, and green components of the color, respectively. Note that
     the order (r,g,b,a) of these components is reversed from the ordering in
     releases of Inventor prior to 2.1.

     If the transparency type is SoGLRenderAction::SCREEN_DOOR, only the first
     transparency value will be used. With other transparency types, multiple
     transparencies will be used.

     SoPackedColor uses less memory than SoBaseColor or SoMaterial to store
     multiple color and transparency values. It can be used in cases where
     space is critical.

FIELDS
     SoMFUInt32          orderedRGBA
          Defines the packed colors.


METHODS
                         SoPackedColor()
          Creates a packed color node with default settings.

     static SoType       getClassTypeId()
          Returns type identifier for this class.


ACTION BEHAVIOR
     SoGLRenderAction, SoCallbackAction
          Sets the current base (diffuse) color(s) in the state.


FILE FORMAT/DEFAULTS
