Detailed Description

Cuboids.

Cuboids implement convex hexahedra, i.e. polyhedra with six faces.

Constructor & Destructor Documentation

Cuboid() [1/2]

Cuboid::Cuboid ( const Box & box )

explicit

Create a cuboid.

Parameters

box

The box.

Cuboid() [2/2]

Cuboid::Cuboid ( const Vector & a000, const Vector & a100, const Vector & a010, const Vector & a110, const Vector & a001, const Vector & a101, const Vector & a011, const Vector & a111 )

explicit

Create a cuboid given vertexes.

Parameters

a000,a100,a010,a110,a001,a101,a011,a111

Vertexes.

Member Function Documentation

GetQuadrangle()

Quadrangle Cuboid::GetQuadrangle ( int i ) const

inline

Returns tthe i-th quadrangle.

Parameters

i	Quadrangle index.

Normal()

Vector Cuboid::Normal ( int i ) const

inline

Returns the normal to the i-th quadrangle face of the cuboid.

Parameters

i	Quadrangle index.

Rotate()

void Cuboid::Rotate

(

const Matrix &

r

)

Rotates a cuboid.

Parameters

r	Rotation matrix.

Scale()

void Cuboid::Scale

(

const Vector &

s

)

Scales a cuboid.

Note that this function handles negative coefficients in the scaling vector (by swapping coordinates if need be).

Parameters

s	Scaling vector.

Translate()

void Cuboid::Translate

(

const Vector &

t

)

Translates a cuboid.

Parameters

t	Translation vector.

Vertex() [1/2]

Vector Cuboid::Vertex ( int i ) const

inline

Returns the i-th vertex of the cuboid.

Same as operator[].

Parameters

i

Vertex.

Vertex() [2/2]

Vector Cuboid::Vertex ( int i, int j ) const

inline

Returns the j-th vertex of i-th quadrangle face of the cuboid.

Parameters

i	Quadrangle.
j	Vertex.
