Detailed DescriptionThe SoPackedColor class is a node for setting diffuse and transparency material values​. This node provides a convenient way of setting diffuse colors and transparency values with packed 32-bit RGBA vectors​. FILE FORMAT/DEFAULTS: PackedColor { orderedRGBA 0xccccccff } See also SoBaseColor

Member Function Documentation

SoType SoPackedColor::getTypeId (void) const [virtual]Returns the type identification of an object derived from a class inheriting SoBase​. This is used for run-time type checking and 'downward' casting​. Usage example: void foo(SoNode * node) { if (node->getTypeId() == SoFile::getClassTypeId()) { SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type } }For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses​. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode​.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine​.h (for engine classes) and so on​. For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups​. Implements SoBase​.

const SoFieldData * SoPackedColor::getFieldData (void) const [protected], [virtual]Returns a pointer to the class-wide field data storage object for this instance​. If no fields are present, returns NULL​. Reimplemented from SoFieldContainer​.

void SoPackedColor::doAction (SoAction * action) [virtual]This function performs the typical operation of a node for any action​. Reimplemented from SoNode​.

void SoPackedColor::GLRender (SoGLRenderAction * action) [virtual]Action method for the SoGLRenderAction​. This is called during rendering traversals​. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method​. Reimplemented from SoNode​.

void SoPackedColor::callback (SoCallbackAction * action) [virtual]Action method for SoCallbackAction​. Simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph​. Reimplemented from SoNode​.

SbBool SoPackedColor::isTransparent (void)Returns TRUE if there is at least one RGBA vector in the set which is not completely opaque​.

void SoPackedColor::notify (SoNotList * l) [protected], [virtual]Notifies all auditors for this instance when changes are made​. Reimplemented from SoNode​.

Member Data Documentation

SoMFUInt32 SoPackedColor::orderedRGBASet of packed 32-bit RGBA vectors​. The most significant 24 bits specifies 8 bits each for the red, green and blue components​. The least significant 8 bits specifies the transparency value, where 0x00 means completely transparent, and 0xff completely opaque​.
