Topic: Menger Sponge raymarching in 512b using Canvas. (Page 1 of 1)

Some of you might have seen Spongy, the 128b DOS intro raymarching a Menger Sponge. Well, once I picked my jaw from the floor I wondered how big/small such effect could be in JavaScript. My gut feeling was saying 512 bytes but aiming for a very small footprint dictated to go brute force and I wasn't sure how to get a decent framerate for something actually working in base 3 ( in a Menger Sponge you divide the current cube in 3x3x3 and recurse ).

So, without further ado, here comes JSpongy a level 5 Menger Sponge raymarcher in 512 bytes.

Hope you like it.

PS: it works best in Chrome and Firefox.
PS2: I have to get my hands on build of Opera with Carakan to see how it goes.

very very cool P01

..and the site has a fresh/clean look to it..good work!

saw this on pouet!
awesome job again po1!

Thanks

Great stuff

Mesmerising!

Awesome. Can you make it zoom?

What do you mean by zoom ?

I've been lookng at the mostly unstyled version and got it down to 379 bytes.

I mean it's a fractal ... but atm looks like it only follows one big tunnel ... the camera could fly into a smaller 'hole' every once in a while

edit: well actually it's not a fractal ... but it could be

Ah like that. Well, the Menger Spong IS a fractal, and I compute it as such.

The only limit to flying inside 'holes' is the number of bytes it would take to implement such camera path, and I really wanted to fit in 512 bytes or less. However the calculation of the fractal supports that. No problem.

well i actually expected the camera path to be of fractal calculation too
