Detailed Description

Perspective camera with depth of field.

This class implements a simple perspective camera model. It uses an infinitesimally small aperture, creating an infinite depth of field.

Member Function Documentation

activate()

virtual void PerspectiveCamera::activate ( )

inlineoverridevirtual

Perform some action associated with the object.

The default implementation throws an exception. Certain objects may choose to override it, e.g. to implement initialization, testing, or rendering functionality.

This function is called by the XML parser once it has constructed an object and added all of its children using addChild().

Translation and scaling to shift the clip coordinates into the range from zero to one. Also takes the aspect ratio into account.

Reimplemented from NoriObject.

Definition at line 53 of file perspective.cpp.

addChild()

virtual void PerspectiveCamera::addChild ( NoriObject *  child )

inlineoverridevirtual

Add a child object to the current instance.

The default implementation does not support children and simply throws an exception

Reimplemented from NoriObject.

Definition at line 113 of file perspective.cpp.

sampleRay()

Color3f PerspectiveCamera::sampleRay ( Ray3f &  ray, const Point2f &  samplePosition, const Point2f &  apertureSample  ) const

inlinevirtual

Importance sample a ray according to the camera's response function.

Parameters

ray	A ray data structure to be filled with a position and direction value
samplePosition	Denotes the desired sample position on the film expressed in fractional pixel coordinates
apertureSample	A uniformly distributed 2D vector that is used to sample a position on the aperture of the sensor if necessary.

Returns

An importance weight associated with the sampled ray. This accounts for the difference in the camera response function and the sampling density.

Implements Camera.
