From: Anselm Hook
To: All
Subj: 3d 4d and so on
I've uploaded a couple of programs to demonstrate three and four dimensional
graphics on an amiga computer. Both programs essential code was created by a
third program i call matfinder, this program creates a matrix for N dimensions,
so theoretically you could take matfinder, modify it appropriately and come
up with an 11 dimensional matrix (Hypothesized # of dimensions to universe)
Anyway the programs are at a very crude stage, i just have not had time to
work on them, the reason i uploaded them now is that i will not be able to
look at the code for about another month, I may as well let you enjoy some of
the neat transformations
You pass parameters to both programs in two ways, first the program expects
to find in the same directory a file called either thredata or fourdata
depending on the dimensionality of the programs accordingly. Secondly the
programs expect a parameter specifying which planes to turn on, this is passed
as a bit pattern. As an example: To rotate all six planes of the 4d object
ARROW pass the program a number with the first 6 bits active, ie: four 63.
Warning: I don't suggest turning all the planes on because you will miss half
the fun, some perspectives simply cannot be achieved by a linear increase of
radians across all dimensions (for example, try thre 7 (all active), you will
More ?
never see the arrow point left). In 4d you can get shrinks and flips and
thru-axis flips and strange combinations of these.
Please don't go ahead and modify these programs, I will be updating them
when I get back to Canada in about a month (strangly enough I am leaving for
California today), for now i am the keeper of the source or whatever you want
to call it. Mods I may make include latffp,requesters,menus,gadgets... all
the fun stuff. Oh and also this program is very crude i repeat for example
all rotations take place in the positive direction, I'll change that too, but
for now have fun with it.
NOTE: if for some reason the code downloaded improperly you may get
another copy from these numbers in Calgary, Canada: (403) 287-3638 after 6pm
MST, 282-1703 (24 hr). Both these systems are fido nets.
I saw word on Mindshadow, It may be a bad game, but it was the first and
they made money on it accordingly, i can solve the game in five moves...
Hmmm anything else???, these long-distance charges really hamper relaxed
thought. As a final note, I'll be calling my home BBS's, if anybody wants to
chat, physically nose to nose, leave a message there.
Thanks. ANSELM
