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.


SoMFUInt32 orderedRGBA

Creates a packed color node with default settings.

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

Action Behavior

SoGLRenderAction, SoCallbackAction
