Function Documentation

build_tiled_samples_3d()

void build_tiled_samples_3d ( const uint32  X, const uint32  Y, const uint32  Z, float *  samples  )

inline

Build a 3d lattice of 3d points with low discrepancy. The samples are arranged in a SOA layout, so that the point (x,y,z).i coordinates are located at (x + y*X + z*X*Y*3 + i*X*Y) (i.e. if the set has Z slices of X*Y points, there will be Z*3 consecutive arrays of X*Y floats).

irandom()

uint32 irandom ( const uint32  N )

inline

utility function for [0,N) integer randoms

load_samples()

void load_samples ( const char *  nameradix, const uint32  X, const uint32  Y, const uint32  Z, float *  samples  )

inline

load a set of 3d samples from a file

mj_3d()

void mj_3d ( uint32  X, uint32  Y, uint32  Z, sample_set_3d  p, const uint32  slice  )

inline

build a 3d multi-jittering pattern

random()

float random ( )

inline

utility function for [0,1) randoms
