Detailed Description

List storage for the image-space contributions ("splats") of a path sample generated using PathSampler.

Member Typedef Documentation

typedef std::pair<Point2, Spectrum> mitsuba::SplatList::Splat

Represents a screen-space splat produced by a path sampling technique.

Constructor & Destructor Documentation

mitsuba::SplatList::SplatList ( )

inline

Member Function Documentation

void mitsuba::SplatList::accum ( size_t  i, const Spectrum &  value  )

inline

Increases the contribution of an existing splat.

void mitsuba::SplatList::append ( const Point2 &  samplePos, const Spectrum &  value  )

inline

Appends a splat entry to the list.

void mitsuba::SplatList::clear ( )

inline

Clear the splat list.

const Point2& mitsuba::SplatList::getPosition ( size_t  i ) const

inline

Return the position associated with a splat in the list.

const Spectrum& mitsuba::SplatList::getValue ( size_t  i ) const

inline

Return the spectral contribution associated with a splat in the list.

void mitsuba::SplatList::normalize

(

const Bitmap *

importanceMap = NULL

)

Normalize the splat list.

This function divides all splats so that they have unit luminance (though it leaves the luminance field untouched). When given an optional importance map in 2-stage MLT approaches, it divides the splat values by the associated importance map values

size_t mitsuba::SplatList::size ( ) const

inline

Returns the number of contributions.

std::string mitsuba::SplatList::toString

(

)

const

Return a string representation.

Member Data Documentation

Float mitsuba::SplatList::luminance

Combined luminance of all splats in this sample.

int mitsuba::SplatList::nSamples

Total number of samples in the splat list.

std::vector<Splat> mitsuba::SplatList::splats

A series of splats associated with the current sample.
