Function Documentation

areaOrtho()

float smaa_detail::areaOrtho ( float p, float d, float offset )

inline

Smoothing function used by the area calculation.

Returns the area under the line between two edge endpoints that overlaps the pixel at position p, for a smooth step profile.

calcAreaOrtho()

void smaa_detail::calcAreaOrtho ( int d1, int d2, int e1, int e2, float offset, float & r, float & g )

inline

Compute the area for a specific orthogonal edge configuration.

Parameters

d1	distance from pixel to left/top endpoint
d2	distance from pixel to right/bottom endpoint
e1	crossing edge flag at endpoint 1 (0 or 1)
e2	crossing edge flag at endpoint 2 (0 or 1)
offset	sub-pixel offset (0..6 mapped to -0.25..0.25 etc.)
result	output RG values (two blend weights)

subtexOffset()

float smaa_detail::subtexOffset ( int idx )

inline
