Detailed Description

Author

Marcus D. Hanwell

The GeometryNode contains any Drawable objects, and is the only node type that results in anything being rendered to the screen.

Member Function Documentation

accept()

void accept ( Visitor &  )

overridevirtual

Accept a visit from our friendly visitor.

Reimplemented from Node.

addDrawable()

void addDrawable

(

Drawable *

object

)

Parameters

object

Drawable object to be added.

removeDrawable()

bool removeDrawable

(

Drawable *

node

)

Parameters

node	Node to be removed.

Returns

True if the node was removed, false if it was not found.

drawable()

Drawable* drawable

(

size_t

index

)

Parameters

index

The index of the child.

Returns

A pointer to the child node, or nullptr if the index is out of range.

hits()

std::multimap<float, Identifier> hits	(	const Vector3f &	rayOrigin,
		const Vector3f &	rayEnd,
		const Vector3f &	rayDirection
	)		const

Return the primitives that are hit by the ray.

Parameters

rayOrigin	Origin of the ray.
rayEnd	End point of the ray.
rayDirection	Normalized direction of the ray.

Returns

Sorted collection of primitives that were hit.

areaHits()

Core::Array<Identifier> areaHits

(

const Frustrum &

frustrum

)

const

Return the primitives within the supplied frustrum.
