public class SoPackedColor extends SoNode
Node that defines base colors using packed representation.SoPackedColor
is similar toSoBaseColor
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 Open Inventor prior to 2.1 and is platform independent.SoPackedColor
uses less memory thanSoBaseColor
orSoMaterial
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 anSoVertexProperty
node (which also has an orderedRGBA field) to specify diffuse color and transparency.If setOverride() was called on an
SoMaterial
node higher in the scene graph and either the diffuseColor field or the transparency field is not ignored (setIgnored()), then the color and transparency values from theSoMaterial
node are used instead of the values in this node. It is not currently possible to override just the color or just the transparency.File format/default:
