Constructor Details

OGLTriggeredNode

public OGLTriggeredNode()

Creates a new triggered node where the trigger starts set. In other words, this will call the triggered function once, and not again until triggered.

OGLTriggeredNode

public OGLTriggeredNode(boolean triggerFlag)

Creates a new triggered node where the trigger starts set or unset, according to the programmer.

Parameters:

triggerFlag - the initial state of the trigger.

Method Details

onDisplay

public final void onDisplay(GL gl)

Description copied from interface: OGLNode

Displays this node. The rendering thread for the target window enters this method, so it is safe to call all OGLGraphics functions here.

Specified by:

onDisplay in interface OGLNode<GL extends OGLGraphics>

Parameters:

gl - the graphics object used for issuing commands to OpenGL.

setTrigger

public void setTrigger()

Sets the trigger on this node.

doTriggeredDisplay

public abstract void doTriggeredDisplay(GL gl)

This is the method called by onDisplay(OGLGraphics) for when the triggered method needs to run.

Parameters:

gl - the OGLGraphics context.
