Contributions to this software library are always welcome. Please ensure that you post program listings rather than .raw files. They give a reasonable idea of what your program does without having to load them into a DM42 and you can also include comments in your code. Check out the following link for a decoder/encoder: http://www.swissmicros.com/dm42/decoder/

You can then copy/paste the listing and post it in "code" tags.

psycho wallpaper

Post by mcc » Mon Apr 15, 2019 6:29 pm

Hi,

(if my memory serves me right...)
A long time ago (it was the ATARI800/C64 time) this or a similiar program was printed in one of the home computer
magazines and it was called "Psycho Tapete" (german for "psycho wallpaper)....I think (read: dont know for sure) it
was printed in the "c't", a german computer magazine, which is still available.
I implemented this from my memory...so it may be totally different, but the result looks very similar to the program
"Psycho Tapete"... :)

What does it? It creates screens like these:
20190415-19111366.bmp
20190415-19111366.bmp (12.31 KiB) Viewed 1778 times
20190415-12000306.bmp
20190415-12000306.bmp (12.31 KiB) Viewed 1778 times
The raw file is in the attachment.
The code is here:

Code: Select all

00 { 135-Byte Prgm }
01▸LBL "psyplt"
02 MVAR "GrMod"
03 MVAR "mod"
04 MVAR "fac"
05 VARMENU "plot"
06 STOP
07 EXITALL
08 RCL "mod"
09 STO 02
10 RCL "fac"
11 STO 03
12 RCL "ResY"
13 STO 01

21 DIM "pltp"
22 GROW
23 INDEX "pltp"
24 COMPLEX
25 STO× "pltp"
26▸LBL 01
27 RCL 00

29 RCL 01
30 COS
31 ×
32 RCL× 03
33 IP
34 RCL 02
35 MOD
36 X≠0?
37 GTO 02
38 RCL 00
39 RCL 01
40 COMPLEX
41 →
42▸LBL 02
43 DSE 00
44 GTO 01
45 RCL "pltp"
46 PIXEL
47 DSE 01
48 GTO 00
49 END
I am still unsure, what the fastest way is to handle the contents of the complex matrix:
Each row will have a different number of points to plot.
1.) With each row delete the previous matrix create a new 1x1 matrix, complexify it, set grow mode, add points, plot the matrix and so on.
2.) Create a full sized matrix (a complete row), add points and count them, redim the matrix before each PIXEL commmand, reset counter and so on.
3.) Pixel each point
4.) Any other more speedy version anyone?

But in any case: Have fun!

Cheers!

Have fun!

Hi mcc,

This is a cute program. I really like it!

Did you also enter 2 for GrMod? You did not mention what you entered for GrMod, but an entry was expected. I tried the following entries and found some interesting images.

GrMod=2, mod=2, fac=2000
GrMod=2, mod=4, fac=4000
GrMod=2, mod=6, fac=6000
GrMod=2, mod=8, fac=8000

As you can tell, I am having fun with this program!

Best,

Bob

Hi Bob,

I am happy to hear that this little program has found a friend :)

Currently I am trying to speed up the processing of the data.
For example, the cos() is calculated much too often. Will see,
when there will be time for this... :)

The wallpapers I posted are done with GrMod 3.

Have FUN!
Cheers!

Hi,

the program was updated: It is now a little faster.
The output is a tiny bit different. It seems to be a shift by one pixel or such...
I am still searching the reason.

Here is the code:

Maybe he fixed it since I just tried it and got the zip file in which was located the raw file. There was no error.

Hi Meino,

I am pleased with the version of the program that I already have. It may not be worthwhile to put a bit of time into modifying the program so that it runs a little faster. I have now run the program with the following inputs. All of them run fine.

GrMod=3, mod=2, fac=2000
GrMod=3, mod=4, fac=4000
GrMod=3, mod=6, fac=6000
GrMod=3, mod=8, fac=8000
GrMod=2, mod=2, fac=2000
GrMod=2, mod=4, fac=4000
GrMod=2, mod=6, fac=6000
GrMod=2, mod=8, fac=8000

There are of course many more inputs that one could use!

Cheers,

Bob

Hi Meino,

Thank you for your efforts with writing this program and in also trying to update it to make it run more efficiently!

Cheers,

Bob
