Reflex - Mathematica - Real C64, 8580 SID

[@TheArtofHouseStudio]

That's one hell of a tune and sound from the SID

[@ermenegildoluponi3184]

Una vera merda

[@keithlegg]

The C64 does not even have a floating point unit. They had to hack all this in assembly language. Seriously tight code

[@omzk]

C64 doesn't even have integer multiplication..

[@lavinagotu5934]

Hardcore stuff. Congrats! Greetings from the Commodore Plus4 demoscene.

[@patsfan4life]

Lavina / Gotu What’s a Plus 4?

[@logan8640]

google commodore plus4

[@ladeluff_]

Woah. The music in this demo is truly astronomical work of 8 bit sid magic

DID I JUST SEE A FULLY 3D RENDERED MAZE THAT YOU CAN WALK AROUND ON A CONSUMER MACHINE FROM THE 1980s !?!?!?!

[@davianngames3326]

Amazing how a few filled circles can look like spheres just by Z ordering..

[@JoeyLutes]

such a cool trick..

[@Marius-vw9hp]

Was my favourite part of the whole demo

[@patsfan4life]

I only wish I knew what that meant....

[@fghsgh]

@@patsfan4life They're talking about 1:24. It looks like spheres in 3D, but actually it are just circles of different sizes that are drawn on top of each other. Z ordering is what specifies which circle should be on the foreground and which should be on the background.

[@Synthematix]

c64 loading music is more entertaining to me than any spectrum game itself

[@f.r.x]

This is religion, this is GREAT! Amazing SID.

[@johneymute]

Mind blowing masterpiece!!!

[@henrywachtel7078]

i now vividly remember that guy, the musician, PVCF from Dresden, Germany, to be super great. Oh, The demo is awesome too ;)

[@Maxsoft9]

Mistrzostwo świata!

[@ericr.7499]

3:11 Rainbow blob is evolving!

[@rigglestad8479]

I'm pretty sure it was a Julia set.

[@axise100]

Just one word, "¡MASTERS!"

[@dimethyltryptamin]

True mastrerpiece :)

[@GerbenWijnja]

That is really impressive.

[@Outlander999]

Just incredible.

[@LeukeGast]

Great demo, I like this one!

[@kevtris]

@Dark0Lord7 Works the same as a mandelbrot set, except you change the initial condition before iterating. changing the condition without panning results in the various julia sets being shown.

[@Eric-lr5ur]

This is fire

[@104d_3rr0r_vince]

They should make an fps game.

[@ProBloggerWorld]

Still top notch.

[@xoen6]

Dudesssss!!!!

[@super-dude-]

nice!

[@MaLoWare]

oh that's nice

[@christianherbst674]

Every time you see is when you wonder: For real? On 8bit?! And yes: it is!

[@addict.challelofap5227]

3:30 what Is it?

[@marzipug5439]

A Julia set.

[@sivalley]

If not for resolution and color depth it's too easy to forget how powerful these machines really were in their hey-day.

[@kangarht]

most of this is just smoke and mirror, half animation half realtime stuff :) fex. a realtime raycaster is 3-4x slower. on c64 and a realtime phong torus is 20x :)

[@adymode]

I don t think their phong like torus is animated or video. - kindof quarter resolved and fuzzy upsampled but the shortcuts work to create a fast scene. Similar less restricted rendering happens at a lower framerate in "Oxyron - ReLIGHTening" for comparison.

[@kangarht]

@@adymode the torus here is more animation than anything, just a few clever table lookups per pixel really. no 3d is involved :)

[@adymode]

@@kangarht No offence but I doubt you would say that if you had ever developed "a few clever table lookups" to do similar :]

[@kangarht]

@@adymode its very simple, the torus' rotation is an animation, and its 2d rotation (around the axis thats orthogonal to the screen) is done by polar mappign the torus animation. or if you want the torus is sliced up into "angles", and by picking which angle is mapped (shown) onto which angle on screen it gets rotated, another benefit of this "angle" approach that the animation can be mirrored, as you see the torus is symmetrical always on the screen to 180 degree. you can do this by a few assembly instructions, as the resolution is small, so every pixel has these few instructions assigned and the polar offsets for the lookps are precalculated. the cube is the same, just a few phases of "true" rotation animated. I code c64 demos since 30 years, I have done much more complex effects, this is a simple thing in my book.

[@АлександрК-р9ъ]

6.45 and more it is incredible. is a c64 so powerfull?

[@rafalkowalczyk8080]

what is code size in KiB?

[@disaster3ad]

just disasm the code

[@monic564]

Ez mi?
