Detailed Description

The SoTransparencyType class is a node for setting the transparency type for shapes.

In earlier versions of Coin/Open Inventor it was only possible to set the transparency mode globally for an entire scene graph, which could be inconvenient if different transparency types was wanted for different shapes.

Here is a screenshot of the different transparency modes used in a single scene.

Destructor.


Member Function Documentation

void SoTransparencyType::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 SoTransparencyType::doAction ( SoAction action) [virtual]

This function performs the typical operation of a node for any action.

Reimplemented from SoNode.

References SoAction::getState(), SoOverrideElement::getTransparencyTypeOverride(), SoField::isIgnored(), SoNode::isOverride(), SoOverrideElement::setTransparencyTypeOverride(), and value.

Referenced by callback(), and GLRender().

void SoTransparencyType::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 SoTransparencyType::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().


Member Data Documentation

The transparency type to use for subsequent shape nodes in the scene graph.
