Public Functions Documentation

function RayDifferential

RayDifferential() =default

function RayDifferential

inline explicit RayDifferential(
    const Point3f & o,
    const Vector3f & d,
    float t_max =INF
)

function has_nans

inline bool has_nans() const

check whether the ray differentials has nans

function scale_differentials

inline void scale_differentials(
    float s
)

scale the differential of the ray

Parameters:

s scale

let \(c\) be the camera position \(o'' = o + s (o \rightarrow o')\) \(d' = c \rightarrow o'\) \(d'' = c \rightarrow o'' = (c \rightarrow o) + (o \rightarrow o'') = d + s (d' - d)\)
