The parameters in this section only have meaning in simulations that result in an image, and will be ignored for numeric output. Note that, formally, the options "Pixel Aspect Ratio" and "Pixel Sample Jitter" from the "Other Settings" area also belong into this section.
This specifies the sample spacing (in pixels) for adaptive subdivision on the image plane.
If two samples differ by more than this amount, a third sample is taken between them.
This option is set with the
Other Settings in the the
Simulation Settings
dialog.
Sets the pixel aspect ratio (height over width) to this
value. Either the x or the y resolution will be reduced so
that the pixels have this ratio for the specified view. If no
value is set, then the x and y resolutions will adhere to the
given maxima. This option is mainly of historical interest,
since nowadays virtually all image displays use square
pixels.
This option is set with the
Other Settings in the the
Simulation Settings
dialog.
Distributed
ray-tracing performs anti-aliasing by randomly sampling
over pixels. A value of one will randomly distribute
samples over full pixels. A value of zero samples pixel
centers only. A value between zero and one is usually
best for low resolution images. If nothing is set here, then
the default of 0.67 is used.
