4 PREFERENCES» Adaptive Sampling: Adaptive sampling allows the raytracer to skip regions thatare already smooth and focus the processing power on regions that are stillnoisy. The various quality settings control a threshold for a region to be consideredas smooth. Setting the control to “Highest Quality” disables adaptiveantialiasing and always samples each pixel with the number of image samplesspecified. While this gives the highest render quality it may waste processingpower on regions that are already smooth.• Preview Quality: Sets the sampling quality to a very low level, resulting inpreview render quality and very short render times.• Low Quality: Sets the sampling quality to low level, resulting in averagerender quality and short render times.• Medium Quality: Sets the sampling quality to medium level, resulting ingood render quality and medium render times.• High Quality: Sets the sampling quality to high quality level.• Ultra High Quality: Sets the sampling quality to production quality level.» Use Clamping Value: Activates clamping of very bright pixels to eliminate whitespots after antialiasing. The value sets the maximum value for a white pixel.Activating clamping and reducing the value reduces the maximum resultingimage color range.» Pixel Filter A pixel filter weights the image samples taken per pixel and thereforecontrols the antialiasing quality of the rendering. High image filter sizes mayresult in blurry image results.» Filter: VRED offers seven filter-algorithms for sampling: Box, Triangle, Gaussian,Mitchell Netravali, Lanczos, BSpline and Catmull Rom.» Size: The pixel filter size defines the number of neighboring pixels in width andheight taken into account for filtering.» Features78
