■ Mitchell. Weights the samples using a curve (steeper than Gauss) centered
on the pixel.
■ Lanczos. Weights the samples using a curve (steeper than Gauss) centered
on the pixel, diminishing the effect of samples at the edge of the filter
area.
Filter Width and Height Specifies the size of the filtered area. Increasing the
value of Filter Width and Filter Height can soften the image; however, it will
increase rendering time.
Contrast Color Clicking [...] opens the Select Color dialog box where you
interactively specify the R,G,B threshold values.
Contrast Red, Blue, Green Specifies the threshold values for the red, blue,
and green components of samples. These values are normalized, and range
from 0.0 to 1.0, where 0.0 indicates the color component is fully unsaturated
(black, or 0 in eight-bit encoding) and 1.0 indicates the color component is
fully saturated (white, or 255 in eight-bit encoding).
Contrast Alpha Specifies the threshold value for the alpha component of
samples. This value is normalized, and ranges from 0.0 (fully transparent, or
0 in eight-bit encoding) to 1.0 (fully opaque, or 255 in eight-bit encoding).
Shadows
Contains settings that affect how shadows appear in the rendered image.
Enable Specifies if shadows are computed during rendering.
Mode The shadow mode can be Simple, Sort, or Segments.
■ Simple. Generates shadow shaders in a random order.
■ Sort. Generates shadow shaders in order, from the object to the light.
■ Segments. Generates shadow shaders in order along the light ray from the
volume shaders to the segments of the light ray between the object and
the light.
Shadow Map Controls if shadow mapping is used to render shadows. When
on, the renderer renders shadow-mapped shadows. When off, all shadows are
ray-traced.
Sampling Multiplier Globally limits shadow sampling for area lights. This is
part of the rendering preset data. This allows draft and low quality presets to
reduce area light sampling. It’s effect is to modulate the inherent sampling
