Detailed Description

Models a perspective camera.

Constructor & Destructor Documentation

PerspectiveCamera() [1/3]

PerspectiveCamera::PerspectiveCamera

(

)

Default constructor.

numberPixelsX and numberpixelsY are set to 500 by default.

PerspectiveCamera() [2/3]

PerspectiveCamera::PerspectiveCamera	(	unsigned int	numberPixelsX,
		unsigned int	numberPixelsY,
		DoubleVec3D	origin = DoubleVec3D(0.0),
		DoubleVec3D	focal = DoubleVec3D(0, 0, -0.75)
	)

Main constructor.

Parameters

numberPixelsX	The width of the camera in pixels. It will define the width of the render.
numberPixelsY	The height of the camera in pixels. It will define the height of the render.
origin	From where the rays are casted.
focal	Its direction defines the camera's and its length defines the camera length.

PerspectiveCamera() [3/3]

PerspectiveCamera::PerspectiveCamera

(

const PerspectiveCamera &

camera

)

Copy constructor.

Parameters

camera

The camera that will be copied.

Member Function Documentation

getFocal()

DoubleVec3D PerspectiveCamera::getFocal

(

)

const

Getter for the camera focal.

Returns

The camera focal.

getNumberPixelsX()

unsigned int PerspectiveCamera::getNumberPixelsX

(

)

const

Getter for the number of pixels in x.

Returns

The number of pixels that compose the camera on the x axis.

getNumberPixelsY()

unsigned int PerspectiveCamera::getNumberPixelsY

(

)

const

Getter for the number of pixels in y.

Returns

The number of pixels that compose the camera on the y axis.

getOrigin()

DoubleVec3D PerspectiveCamera::getOrigin

(

)

const

Getter for the camera origin.

Returns

The camera origin.

getRayGoingThrough()

Ray PerspectiveCamera::getRayGoingThrough	(	double	pixelX,
		double	pixelY
	)		const

Returns a ray going through some pixels.

See my TM's report for an explanation on how the computations work.

Parameters

pixelX	The x coordinate of the pixel through which we want the ray.
pixelY	The y coordinate of the pixel through which we want the ray.

Returns

A ray which origin is the camera's and which direction is such that it goes through the requested pixel.

getWorldHeight()

double PerspectiveCamera::getWorldHeight

(

)

const

Getter for the camera world height.

Returns

The width of the camera in the virtual world.

getWorldWidth()

double PerspectiveCamera::getWorldWidth

(

)

const

Getter for the camera world width.

Returns

The width of the camera in the virtual world.

setFocal()

void PerspectiveCamera::setFocal

(

DoubleVec3D

focal

)

Setter for the camera focal.

Parameters

focal

The new camera focal.

setNumberPixelsX()

void PerspectiveCamera::setNumberPixelsX

(

unsigned int

numberPixelsX

)

Setter for the number of pixels in x.

Parameters

numberPixelsX

The new number of pixels that compose the camera on the x axis.

setNumberPixelsY()

void PerspectiveCamera::setNumberPixelsY

(

unsigned int

numberPixelsY

)

Setter for the number of pixels in y.

Parameters

numberPixelsY

The new number of pixels that compose the camera on the y axis.

setOrigin()

void PerspectiveCamera::setOrigin

(

DoubleVec3D

origin

)

Setter for the camera origin.

Parameters

origin

The new camera origin.
