DKBTrace
This ray tracer was written by David K. Buck and is released as freely
distributable software. The author retains all copyrights but permits
free distribution of the software through any medium. The software may
be used without charge so long as the code is not included in any
commercial product.
The Amiga archive here contains two versions of the raytracer:
traceffp - Fast Floating Point version of the raytracer.
This version will run on any Amiga with sufficient
memory.
trace881 - Math coprocessor version. This version will only
run on 68020 or 68030 based systems that have a
68881 or 68882 math coprocessor.
I usually like having a fairly large stack for this program. If it
crashes on you, try inceasing the stack size.
In addition, the following utilities are provided (these will run on any
AMIGA system).
DumpToIFF - Converts the raw 24 bit output files of the raytracer into
hires HAM images.
syntax:
DumpToIFF [options] input-file [output-file [palette-file]]
options are:
-d Suppress Floyd Steinberg dithering
-pfilename Output a colour palette for the picture
The colour palette for one image may be used in other images.
This is useful for animations in order to force the entire
animation to use the same colour palette.
eg.
DumpToIFF -pmyImage.palette myImage.dis myImage.ham
DumpToIFF myImage2.dis myImage2.ham myImage.palette
Dump2RGB - Converts the raw 24 bit output files of the raytracer into
three separate dump files for red, green and blue.
syntax:
Dump2RGB [options] input-file
options are:
-wxxx Output image width
-hxxx Output image height
Dump2Raw - Same as Dump2RGB but takes the size from the input file
and takes less memory.
Sculpt2DKB - Converts a Sculpt-Animate 3D .scene file into DKB format.
At the current time, smoothed triangles are not supported. The
only information converted is the information on the polygons,
the colours, and the textures. Lightsources, viewpoints, and
world information is currently ignored.
syntax:
Sculpt2DKB scene-file dkb-dat-file
You must edit this file after the conversion to add a viewpoint
and lightsources as needed.
The program documentation can be found in the file DKB.DOC and the
documentation for some Amiga specific utilities may be found in
AmigaUtils.doc.
This program is being distributed in four separate packages:
DKBTrace.lzh: Executables for traceffp and trace881
documentation files
DumpToIFF and Sculpt2DKB executables
DKBData.lzh Many sample data files
DKBSource.lzh Source code for DKBTrace, Amiga utilities, and
IBM Utilities.
DKBPics.lzh Sample pictures produced by the raytracer.
(you could render these yourself using the
data files in the DKBTrace.lzh archive)
There is a document in the DKBTrace.lzh archive which describes the
conversions required to use data files for DKBTrace version 1.2 with
the new 2.0 version. This file is called 12to20.doc
This readme file is in all three archives.
