SoPackedColor — node that defines base colors using packed representation

Action Behavior

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

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.
