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

       PackedColor {
