DESCRIPTIONSoPackedColor 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
