Raytracing Solution Files Using LSRAYF
Use the following utility to ray trace Solution files, compute the luminance at each pixel, and store the results in
a special floating point image format. The lsrayf utility is provided primarily for specialized research applica-
tions. The lsrayf utility syntax is shown in the following example:
lsrayf [options] solution_file image_file
The lsrayf utility is a slight variation of the lsray utility that uses two new file formats, instead of creating images
with standard file formats. The lsrayf utility also outputs energy data without using radiance mapping to convert
mesh One block per mesh.
-db name Alternate name for single block. Default: the input filename without its suffix
and directory path.
-dl name Alternate name for single layer. Default: the input filename without its suffix
and directory path.
-h Print a help message.
-ie Ignore internal errors when reading the 3D Studio file.
-k Do not import instances from the keyframe.
-lc [single
mesh] Layer creation mode.
single One layer for entire object.
mesh One layer per mesh. This is the default.
-li n Maximum light intensity scale. Default is 25000.0.
-m File was produced with 3D Studio MAX and should be interpreted as such.
-nt Do not read texture data in the 3D Studio file.
-o filename Output filename. Files without a .lp extension are given one. If this option is not
used, a .lp extension is substituted for the extension of the input filename.
-s n Scaling factor for dimensions in file.
-se Stop on translation errors. Default: to attempt to continue importing.
-t conversion Coordinate system conversion (any permutation of XYZ without optional mi-
nus signs). Default is XYZ.
-u units Length units of model—mm, cm, m, km, in, ft, or mi. Default is m.
-v Show status messages.
infile Input 3D Studio file.
