Method Detail

apply

public void apply()

set iterates over the light queue and processes each individual light.

Specified by:

apply in class RenderState

See Also:

RenderState.apply()

createStateRecord

public StateRecord createStateRecord()

Specified by:

createStateRecord in class RenderState

extract

public RenderState extract(java.util.Stack<? extends RenderState> stack,
                           Spatial spat)

Description copied from class: RenderState

Extracts from the stack the correct renderstate that should apply to the given spatial. This is mainly used for RenderStates that can be cumulative such as TextureState or LightState. By default, the top of the static is returned. This function should not be called by users directly.

Overrides:

extract in class RenderState

Parameters:

stack - The stack to extract render states from.

spat - The spatial to apply the render states too.

Returns:

The render state to use.
