Detailed Description

A list of renderable objects, sorted in layers.

Such a list is the input to a Viewer object, it is provided by a VScene object.

getTouchableBoundingVolume()

RefPtr< BoundingBall > Wizt::VSceneObjects::getTouchableBoundingVolume ( const RefPtr< ValuePool > & Context ) const

inline

Compute the geometrical bounding box of a "touchable" of objects in the current set of renderable objects.

"Touchable" objects are objects that contribute to the spatial camera navigation. They reside in the render category higher than CELESTIAL_OBJECT but lower than OVERLAY_OBJECT.

insert()

void Wizt::VSceneObjects::insert	(	int	RenderCategory,
		const WeakPtr< VObject > &	what )

Insert a specific object to the list of renderable to the current set of renderables.

This function is called by VScene, for instance.

Parameters

Context	The render context
MinLevel	The start layer of object categories to be rendered
MaxLevel	The end layer of object categories to be rendered

Returns
