Description
Outputs the image file in the binary format. The default data format is output
in the text format described above.
Load specified Parameters file.
Last frame of the animation desired. -af option must be used. Default: last
frame specified in the animation file.
For animations, number of frames per second. -af option must be used. De-
fault: as specified in the animation file.
Print a help message.
Load specified Layer State file.
Do not perform backface culling.
Do not load textures.
Number of reflection bounces to trace. Default is 10.
Custom ray file. Instead of ray tracing the specified view, trace the rays speci-
fied in the ray file. This is useful for making panoramic images. 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 coordinates of each ray (six num-
bers per line). If this option is specified, the -x, -y, -af, -vf, and -svf options are
ignored.
Output per channel.
Ray trace only the rectangular region of interest defined by the lower-left and
upper-right corners.
First frame of animation desired. -af option must be used. Default: as specified
in the animation file.
Recompute shadows from sun and other light sources.
Compute soft shadows. Valid for sunlight source only.
For animations, interval for frame output. -af option must be used. Default is 1.
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.
Verbose. Print information about the status of the image.
Load specified view file.
Image width.
