Detailed Description

Author

Marcus D. Hanwell

This Drawable is capable of storing the geometry for one or more spheres. A sphere is defined by a center point, a radius and a color. If the spheres are not a densely packed one-to-one mapping with the objects indices they can also optionally use an identifier that will point to some numeric ID for the purposes of picking.

Member Function Documentation

accept()

void accept ( Visitor & )

overridevirtual

Accept a visit from our friendly visitor.

Reimplemented from Drawable.

render()

void render ( const Camera & camera )

overridevirtual

Parameters

camera

The current camera to be used for rendering.

Reimplemented from Drawable.

hits()

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

overridevirtual

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.

Reimplemented from Drawable.

areaHits()

Core::Array< Identifier > areaHits ( const Frustrum & f ) const

overridevirtual

Return the primitives within the supplied frustrum.

Reimplemented from Drawable.

setOpacity()

void setOpacity

(

float

o

)

Set the opacity of the spheres in this group.

addSphere()

void addSphere	(	const Vector3f &	position,
		const Vector3ub &	color,
		float	radius,
		size_t	index = MaxIndex )

Add a sphere to the geometry object.

spheres()

Core::Array< SphereColor > & spheres

(

)

Get a reference to the spheres.

clear()

void clear ( )

overridevirtual

Reimplemented from Drawable.

size()

size_t size

(

)

const
