Detailed Description

Class for Tube objects.

This class provides an Object which is a Tune centred at the origin with outer radius 1 and a user-specified inner radius in the range \((0,1)\), as shown below.

Note that the Tube provided in the skeleton code is not complete and returns no RayIntersections from intersect(). This method needs to be implemented correctly as part of the assignment.

Constructor & Destructor Documentation

Tube() [1/2]

Tube::Tube

(

double

ratio = 0.5

)

Tube default constructor.

A newly constructed Octahedron is centred at the origin, and is aligned with the Z-axis It has outer radius 1, and an inner radius specified by the ratio parameter. It extends out to \(Z= \pm 1\) It may be moved, rotated, and scaled through its transform member.

Parameters

ratio

The ratio of the inner and outer radii of the Tube.

Tube() [2/2]

Tube::Tube

(

const Tube &

tube

)

Tube copy constructor.

Parameters

tube	The Tube to copy.

~Tube()

Tube::~Tube

(

)

Tube destructor.

Member Function Documentation

intersect()

std::vector< RayIntersection > Tube::intersect ( const Ray &  ray ) const

virtual

Tube-Ray intersection computation.

Todo:

The Tube-Ray intersection needs to be implemented as part of the assignment.

The intersection of a Ray with an Tube is similar to that of a Cylinder, except:

• There are two curved surfaces.
• The top and bottom caps are rings rather than circles.

Parameters

ray	The Ray to intersect with this Tube.

Returns

A list (std::vector) of intersections, which may be empty.

Implements Object.

operator=()

Tube & Tube::operator=

(

const Tube &

tube

)

Tube assignment operator.

Parameters

tube	The Tube to assign to this.

Returns

A reference to this to allow for chaining of assignment.
