Detailed Description

The ILayerState graph node interface.

To allow finer control over the order in which geometry is rendered within an active Graph::ICamera, it is possible to select an individual render layer by using a Graph::ILayerState node with a given index. Layers with lower indices (default 0) are rendered first, i.e. their objects will be overdrawn by objects contained in layers with higher indices.

In any case, if one layer contains both solid and (semi-)transparent objects, the solid ones are always rendered before the transparent ones. If this order is to be reversed, all solid objects must be put to a layer with an index higher than the current one.

Member Function Documentation

GetNodeInterface() [1/2]

virtual INode* Murl::Graph::ILayerState::GetNodeInterface ( )

pure virtual

Get the mutable Graph::INode interface.

This method returns a mutable pointer to the node's Graph::INode interface, to be able to query or modify common node properties such as active state, visibility or ID.

Returns

The mutable Graph::INode interface, or null if not available

GetNodeInterface() [2/2]

virtual const INode* Murl::Graph::ILayerState::GetNodeInterface ( ) const

pure virtual

Get the constant Graph::INode interface.

This method returns a constant pointer to the node's Graph::INode interface, to be able to query common node properties such as active state, visibility or ID.

Returns

The constant Graph::INode interface, or null if not available

SetLayerIndex()

virtual Bool Murl::Graph::ILayerState::SetLayerIndex ( UInt32  layerIndex )

pure virtual

Set the current layer index.

Parameters

layerIndex

The current layer index to set.

Returns

true if successful.

GetLayerIndex()

virtual UInt32 Murl::Graph::ILayerState::GetLayerIndex ( ) const

pure virtual

Get the current layer index.

Returns

The current layer index.
