Detailed Description

Generic camera interface.

This class provides an abstract interface to cameras in Nori and exposes the ability to sample their response function. By default, only a perspective camera implementation exists, but you may choose to implement other types (e.g. an environment camera, or a physically-based camera model that simulates the behavior actual lenses)

Member Function Documentation

sampleRay()

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

pure virtual

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.

Implemented in PerspectiveCamera.
