Detailed Description

The 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:

Member Function Documentation

void SoPackedColor::initClass ( void  ) [static]

Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.

Reimplemented from SoNode.

void SoPackedColor::doAction ( SoAction action) [virtual]
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.

References doAction().

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.

References doAction().

SbBool SoPackedColor::isTransparent ( void  )

Returns TRUE if there is at least one RGBA vector in the set which is not completely opaque.

References SoMField::getNum(), and orderedRGBA.

Referenced by doAction().

void SoPackedColor::notify ( SoNotList l) [protected, virtual]

Notifies all auditors for this instance when changes are made.

Reimplemented from SoNode.

References SoNotList::getLastField(), SoNode::notify(), and orderedRGBA.


Member Data Documentation

Set 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.

Referenced by doAction(), isTransparent(), notify(), and SoPackedColor().
