Ray Tracing Solution Files Using LSRAY
261
❚❘❘
-lf filename Load specified Layer State file.
-nc Do not perform backface culling.
-nt Do not load textures.
-odd For interlacing, output first frame with odd scanlines. Sets -il option; -af option
must be used. Default: output first frame with even scanlines.
-rb n Number of reflection bounces to trace. Default is 10.
-recover filename Recover scan lines from unfinished image file. Useful for continuing work in case
the processing was interrupted by power failure or other problems. This option
is only supported for SGI rgb image files.
-rf filename Custom ray file. Instead of ray tracing the specified view, trace the rays specified
in the ray file. The format of the ray file is that the first line has width and height
dimensions. The following width x height lines have beginning and end coordi-
nates of each ray (six numbers per line). If this option is specified, the -x, -y, -af,
-vf, and -svf options are ignored.
-roi x1 y1 x2 y2 Ray trace only the rectangular region of interest defined by the lower-left and up-
per-right corners.
-sf n First frame of animation desired. -af option must be used. Default: as specified in
the animation file.
-sh Recompute shadows from sun and other light sources.
-soft Compute soft shadows. Valid for sunlight source only.
-step n For animations, interval for frame output. -af option must be used. Default is 1.
-svf filename...
-evf List of view files. -evf must be used to terminate the list. Output image files cor-
responding to the name of each view file in the list. The image filename is com-
bined with the prefix of each view filename. For example, using an image
filename of data.rgb and view files pnt1.vw, pnt2.vw, and pnt3.vw results in im-
ages named datapnt1.rgb, datapnt2.rgb, and datapnt3.rgb.
-v Verbose. Print information about the status of the image.
-vf filename Load specified view file.
-x n Image width.
-y n Image height. If only width or height is provided, the other dimension is derived
from the aspect ratio of the view. Default is 256.
-w Display the results interactively in the Graphic window. This option can only be
used when the resolution of the image fits within the resolution of the monitor.
The default is to not make use of a window.
