# Line 2550 | Line 2550 | routine discovered by Jon Sargent of Solemma.  This af
2550   that had zero radiance, such as black backgrounds or unlit areas
2551   with -av 0 0 0, when super-sampling was effectively disabled, causing
2552   some loss in accuracy of the results.
2553 +
2554 + Updated Klems Half- and Quarter-bases to match angles currently used
2555 + in WINDOW.
2556 +
2557 + Eliminated most aiming failures for triangular light sources, at the
2558 + expense of conservative sampling near the centroid.  Thanks to
2559 + David Geisler-Moroder for his help on this.
2560 +
2561 + Increased maximum set size to 8191 to avoid set overflow errors.
2562 +
2563 + Added source obstruction test to statistics being kept on which
2564 + sources were visible in adaptive shadow testing code.  Previous
2565 + behavior was likely over-estimating source contributions.
2566 +
2567 + Added diffuse components into maximum directional hemispherical
2568 + reported by checkBSDF, so comparing to 100% is easier for each
2569 + component.
2570 +
2571 + Fixed incorrect calculations in iso2klems script, thanks to
2572 + help from Jacob Jonnson.
