- This file contains an extremely abbreviated description of the command line
- flags, initialization file statements, and data file declarations for Polyray.
- See "polyray.doc" for more details.
-
- Syntax:
-
- polyray datafile [ options ]
-
- Command line options:
-
- -a Perform simple antialiasing (neighbor averaging)
- -A Perform adaptive antialiasing (based on threshold)
- -b pixels pixels calculated between file flushes
- -B Flush the output file every scan line
- -d probability Dither objects using the given probability
- -D scale Dither all rays using the given probability
- -J Perform jittered antialiasing (fixed # of samples/pixel)
- -o filename Output file name (default "out.tga")
- -p bits/pixel Number of bits per pixel 8/16/24/32 (default 16)
- -P pallette Which pallette to use [0=grey, 1=666, 2=884]
- -Q Abort if any key is hit during trace
- -q flags Turn on/off various global shading options
- -r renderer Which rendering method [0=raytrace, 1=scan convert,
- 2=wireframe]
- -R Resume an interrupted trace
- -s samples # of samples per pixel when performing antialiasing
- -t status_vals Status display type [0=none,1=totals,2=line,3=pixel].
- -T threshold Threshold to start oversampling (default 0.2)
- -u Write the output file in uncompressed form
- -v Trace from bottom to top
- -V mode Use VGA display while tracing [0=none,1=VGA]
- -W Wait for key before clearing display
- -x columns Set the x resolution
- -y lines Set the y resolution
- -z start_line Start a trace at a specified line
