Constructor & Destructor Documentation

Sphere() [1/2]

rt::Sphere::Sphere

(

double

r

)

Make a new sphere at \((0, 0, 0)\).

Parameters

r

Sphere() [2/2]

rt::Sphere::Sphere	(	const vector &	pos,
		double	r
	)

Make a new sphere.

Parameters

pos	The location of the sphere
r	The ray of the sphere

Member Function Documentation

hits()

std::vector< hit > rt::Sphere::hits ( const euclidian &  global_e ) const

virtual

Compute hits between the sphere and an euclidian.

Parameters

e	An euclidian in the global space referential.

Returns

A list of hit. If no hit occurs, the list is empty.

Implements rt::Geometry.

normal()

vector rt::Sphere::normal

(

const vector &

v

)

const

Compute a normal of the sphere from a local position.

Returns

A normal vector.

tangent()

vector rt::Sphere::tangent

(

const vector &

o

)

const

Compute a tangent of the sphere from a local position.

Returns

A tangent vector.

uv()

vector rt::Sphere::uv ( const element &  ) const

virtual

UV-map a surface element on the sphere.

Returns

The surface element coordinate on a texture for the UV-mapping.

Implements rt::Geometry.
