public class SoPackedColor extends SoNode
Node that defines base colors using packed representation. SoPackedColor is similar to SoBaseColor in that it sets the base 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.

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. However, for geometry nodes that have a *vertexProperty* field, the best practice is to use an SoVertexProperty node (which also has an orderedRGBA field) to specify diffuse color and transparency.

As described here, the orderedRGBA field of this class can be overridden by other property nodes.

File format/default:

PackedColor {

    orderedRGBA 0xccccccff
}

Action behavior:

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