FILE: ReadMe.first
Introduction to contents of disk.
The old TTDDD programs "ReadTDDD" and "WriteTDDD" have been replaced by
the new all-purpose "ReadWrite" filter that supports Imagine 2.0 (on back
to Turbo Silver). Please see the other README.R* file for a more complete
discussion.
On this disk you will also find SQuad, TSTeX, and a few examples objects.
When using SQuad, simply execute it without arguments to get usage
information. You can generate the TDDD file in one step if you are not
interested in editing the TTDDD file. For example (in the Examples
directory):
SQuad 0.01 0.01 | ReadWrite -tddd > die.tddd
SQuad 0.01 2.0 2.0 | ReadWrite -tddd > thing.tddd
Before using TSTeX, you must let the program know where the TeX fonts
are located. From the CLI, simply type "assign TeX: TTDDD_Distribute:"
before you run TSTeX for the first time. (Unless, of course, you already
own AmigaTeX, in which "TeX:" is probably already assigned properly.)
TSTeX will prompt you for lines of text, and after you are
through, hit CTRL-\ (end of file) and TSTeX will create the TTDDD file for
you. These files are often HUGE, so make sure you have plenty disk space
for it before starting. For example (also in the Examples directory):
TSTeX > GML.ttddd

[CTRL-\] (Don't type this out, just hold down the CTRL key, and hit '\')
ReadWrite -tddd < GML.ttddd > GML.tddd
I have provided a couple TeX fonts on this disk (in PK format). The
TeX fonts are in the public domain. I highly recommend AmigaTeX, which of
course, comes with the complete set of TeX fonts. Call Tomas Rokicki at
(415) 32-AMIGA [voice] or (415) 32-RADIO [BBS] (he prefers that you call his
BBS) and ask about his awesome AmigaTeX, Preview, and AmigaMetaFont packages.
I also whipped up a little threaded screw example, called "Thread", and
included the source. Type "Thread" for usage information.
For a quick introduction to using "readwrite", cd to the "Examples" directory,
which contains some old Turbo Silver objects (using the "External" object chunk,
which Imagine does not support). To convert the "chain.ttddd" description into
an Imagine object, type: ":readwrite -tddd < chain.ttddd > ram:chain.iob", and
be prepared to wait while the objects all get loaded in, converted, and written
out. ReadWrite also has another option, called "-merge" that will optimize
the points and edges by removing redundancies. This proceedure is very time
consuming because it is an "N^2" algorithm. That is, if you double the number
of points it has to process, you will quadruple the processing time. It is
never really necessary to use "-merge" unless you absolutely know that there
is a great deal of redundancy in your object, but I have included it because it
was helping me to debug my general-object morphing algorithm (that is not finished
yet).
Have fun, and write to me if you come up with any algorithmic object
generators that you think are useful. By the way... check out Essence, a
powerful set of 66 algorithmic textures for the FPU versions of Imagine and
Turbo Silver! (I co-authored it with Steve Worley, of computer graphics fame.)
