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.

	)

Calls VRenderContext::render(), called by Viewer::render().

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: The number of objects that have been rendered.
