Parameters

name	Instance name of the object to find

Returns: A pointer to the object if it is in the group, otherwise NULL

DisplayObject* FindByName ( DisplayObject * obj )

Returns: A pointer to the object if it is in the group, otherwise NULL

Reimplemented in ComponentBase.

DisplayObject* FindByQualifiedName ( const char * name )

virtual DisplayObject* Pick3D	(	const Vector &	winLoc,
		const Vector &	logicalCoords,
		float	scale,
		const Vector &	directionVector,
		Vector &	collisionWinLoc,
		const OpenGLMatrices &	drawnMatrices
	)

virtual

Attempts to pick an object in 3D and accounting for dynamic rotations and translations of this object or parent objects. It also looks at the pickable status and attempts to return the "Best" pick if that is what is desired.

Note: This method will pick objects in the scene based on a pick ray starting at winLoc and pointing into the screen. It will not pick objects behind the depth specified by winLoc.z. Typically winLoc.z should be set to 0 to ensure that the pick ray starts at near clip plane.

Parameters

winLoc	Device coordinates for the mouse click. Z value should be set to 0 to ensure pick ray starts at near clip plane.
logicalCoords	The start of the pick ray in logical coordinates. Should be calculated from the winLoc using this->WindowToLogical(winLoc, logicalCoords, &directionVector).
scale	Current window scale. Affects picking radius of outlines. Initial value should typically be 1.0.
directionVector	The direction of the pick ray in logical coordinates. Should be calculated from the winLoc using this->WindowToLogical(winLoc, logicalCoords, &directionVector).
collisionWinLoc	Returns where the pick vector intersects the object that is hit in device coordinates.
drawnMatrices	The matrices used to draw the object, including matrices set by parents that may have dynamically rotated, translated or scaled this object. Initial value should typically be a default OpenGLMatrices() object.

Returns: The object that was hit, or NULL if no object hit
