- 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.
