Title: Axe plasma
Post by: Matrefeytontias on April 09, 2012, 09:56:30 am

Hi !

With the help of KKI (from the SdZ), we made this cool plasma effect in Axe :

Spoiler For Plasmas:

They are all running at 15 MHz :) enjoy

Coming soon : greyscales !

is this inspired by hallunicate with your nspire cx?
WOOO
hallunicate with your ti-84+

I like it! It reminds me of a program i downloaded a while back called pixel madness by I-don't-remember-who. We need to figure out how Whats-his-name did his pixel madness, and learn from his epic skills!

Waw, that's pretty fast ! How can this work ? O.O

It's by Ben Ryves (I don't know if he's here or not, but he does hang out on Cemetech, especially on IRC). There's a LOT of crazy Z80 optimizations in that program, I'm sure :P

Damn, that's assembly ... I'm not so good at this one <_<

EDIT : we'll try to do bit storing instead of using Pxl-On, that'll be faster.

Wow that looks awesome. Some nice effects can be done with those languages. Was it inspired from this (http://ourl.ca/15772)?

Nope, we started working on it before the news was written (I believe)

Aaah ok I see. The other one is rather trippy with all those colors actually O.O

Well, I plan to try to translate this ASM program into Axe, but as far as I saw, I can't do it alone <_<

Is someone who is interested in helping me converting this ? By the way, I'll help too :D

Up !

After days of works, we reach what we believe that's the fastest we can do ! Look at it running :

I wonder if this concept could be helpful at all?

Yes, I did too. It's not hard. But that's not the point I'm trying to make :P

This is indeed helpful to make a water/plasma engine... but maybe not on a z80 calc ;)
As it is said, you need:
-a physic engine
-a blurring engine
-an anti-blurring engine
And make all that run on a z80 calc would be too slow I guess :(

Title: Re: Axe plasma
Post by: ZippyDee on May 04, 2012, 04:25:29 pm

Well yes, to do all of that...but it doesn't have to be that complex. I mean really, the resolution on the calc allows for quite a lot of variance in the realism of any water or plasma effect you can think of.

Yay, necro post for an update :P

I asked Matrefeytontias for the source to this program because I was thinking of ways to optimise this. I was originally planning to turn a bunch of it directly into assembly, but for those that like pure Axe, I have this.

First, the original program was 900 bytes of compiled code and ran at about 3.9 FPS.

This version is 502 bytes, ~3.8 FPS:

Code: [Select]

:.PLASMA
:.by KKI+MAT
:.Full
:.Precalculs
:[FFFDF5E9DAC6B0987F664E38241509010001091524384E667F98B0C6DAE9F5FD]→GDB2
:0→θ
:Repeat getKey(15)
:L6-1→P
:L6+11→Q
:θ+1 and 31→θ
:{θ*2+24 and 31+GDB2}*8/256→D
:{θ+GDB2}*8/256→E
:.Lignes
:‾1→Y
:While Y++-32
:.Precalculs
:{Y+E and 31+GDB2}→M
:.Colonnes
:‾1→X
:While X++-48
:.Couleur
:M+{X+D and 31+GDB2}
:+{X+Y+D+E/2+θ and 31+GDB2}→Z
:.Init/Decale
:!If X and 3
:0→{P++}
:0→{Q++}
:Else
:{P}*4→{P}
:{Q}*4→{Q}
:End
:If Z≤576
:{P}++
:End
:If Z≤384
:{Q}++
:{}++
:End
:If Z≤192
:{Q}++
:{P}++
:{}++
:End
:End
:P+12→P+12→Q
:End
:DispGraph
:End

And I am sure there are some obvious optimisations left, but I am not that great of an Axe programmer :P
For those that want a little more speed and size optimisations, I included assembly code in this version:
450 bytes compiled, ~4.8 FPS

Code: [Select]

:End
:P+12→P+12→Q
:End
:DispGraph
:End

It has also come to my attention that some of the Axe code that I replaced with Assembly compiles to the same thing.

Note that the code was compiled with Axe v1.2.1 and run at 6MHz

You know... that stuff reminds me of those monochromatic 83/85 demos a few years ago and those Commodore 64 animations :P. It looks really cool
