Field Documentation

edge_threshold

float R2_fxaa_t::edge_threshold

The minimum amount of local contrast required to apply the algorithm. The range of useful values is [0.063, 0.333], where: 0.333 - too little (faster) 0.250 - low quality 0.166 - default 0.125 - high quality 0.063 - overkill (slower)

edge_threshold_minimum

float R2_fxaa_t::edge_threshold_minimum

Trims the algorithm from processing darks. The range of useful values is [0.0312, 0.0833], where: 0.0833 - upper limit (default, the start of visible unfiltered edges) 0.0625 - high quality (faster) 0.0312 - visible limit (slower)

subpixel_aliasing_removal

float R2_fxaa_t::subpixel_aliasing_removal

The amount of subpixel aliasing removal. The range of useful values is [0.0, 1.0], where: 1.00 - upper limit (softer) 0.75 - default amount of filtering 0.50 - lower limit (sharper, less sub-pixel aliasing removal) 0.25 - almost off 0.00 - completely off
