i don't get it... why do you need so many variables??? awesome though!

NXTGeek NXTGeek 3 months, 3 weeks ago

would it be poassible to remake this in scratch 1.3 and utalize the new features?

Canthiar Canthiar 3 months, 2 weeks ago

I don't know what new features this would take advantage of. When square root and trig functions were added in 1.2 I was able to clean up a lot of code.

I finally got it up on a site - thing! http://img515.imageshack.us/img515/7974/picture1il0.png only a week and a half after I did it too!

boinoinoi boinoinoi 6 months, 3 weeks ago

Okay, so after I had it all finished, since it was on a mac and I don't usually use macs I was trying to find the printscreen shortcut when it started all over. The second time it took a little more than 24 hours. Unfortunately, the image is on the other computer. I'l have it later.

boinoinoi boinoinoi 6 months, 4 weeks ago

I have it going in pen size one inside scratch at turbo speed and it's been gong for a little less than 12 hours straight and it's not quite half way done...

DarthPickley DarthPickley 7 months ago

3/7

DarthPickley DarthPickley 7 months ago

no, more like... 2/5ths

DarthPickley DarthPickley 7 months ago

~1/3 done

DarthPickley DarthPickley 7 months ago

Oh, I'm giving up on the online one. I'll just put it on 10 size and wait for a preview.

DarthPickley DarthPickley 7 months ago

~1/4 of the way done (not online)

DarthPickley DarthPickley 7 months ago

This is really, just, amazing. What might it take, to try to run this several times, at, maybe, 5 pen size, with different FOVs, and then save all of the pictures, and create an interactive thing?

DarthPickley DarthPickley 7 months ago

already, it is ~1/5th of the way done! It is mostly just the floor right now, though...

DarthPickley DarthPickley 7 months ago

For faster speed: download and run in Turbo Speed, by shift-clicking "extras", "set single stepping", "turbo speed". Mine (offline) is already about 3 times further than the online one, both with pensize 3, and started at approximately the same time.

... wow... wow... wow... wow... this... is... amazing... did u tel it wat pic to draw at different sizes/FOV?

anthony3329 anthony3329 1 year ago

can u explain it? im not a math smarticle, so i dont get it...

NXTGeek NXTGeek 1 year, 1 month ago

can you use multiple pens to speed up the process?

Canthiar Canthiar 1 year, 1 month ago

I've done experiments where I've removed the broadcasts so that I can do multiple pens and it goes a little bit faster.

i agree with redsooty9

inuwali inuwali 1 year, 1 month ago

Very nice job. Your Scratch-fu is intimidating. I think we can all agree that Scratch is Turing-complete! It's fascinating to see how you can adapt a recursive algorithm to a non-procedural programming environment.

Canthiar Canthiar 1 year, 1 month ago

I had to cheat on what is normally done through recursion by doing a single level reflection after the initial pass. Color is also not done through RGB components in Scratch so reflection is based on intensity.

You can't do a comment box. I put those in when the beta was out and they removed the ability to do comments since then.

Oh, wow. I'm sorry, I was looking at your previous raytracer code. This one WAS made using Scratch 1.2... lol. *examines code* ...Oh, wow! These notes are helpful! I'm now going to attempt to understand some of the code. This is probably the ultimate Scratch project I'd like to figure out. Serious thumbs up for this, Canthiar!

BATzerk BATzerk 1 year, 7 months ago

(*MORE incredible... because even THIS is already way past incredible!)

BATzerk BATzerk 1 year, 7 months ago

OMGH, Canthiar, this is just INSANE. You are brilliant. (Now that the new version of Scratch is out, have you considered cleaning up your code with the new numbers functions? Namely the square root one? I was actually thinking of doing that with your code, just so I can figure it out quicker.) Hey... you ever think you'll get a working version with anti-aliasing? ...THAT would be incredible!

cooldude16 cooldude16 1 year, 7 months ago

if u put it on pen size 25, it won't make a picture

Canthiar Canthiar 1 year, 7 months ago

POVRay used to be pretty slow running with computers in the early 90's. I think it ran a little faster for scenes as simple as this. Complicated scenes ran really slowly. I think in the early versions they didn't have any of the spatial partitioning that is in there now.

Jens Jens 1 year, 7 months ago

Fantastic, this gets ever more complex and brilliant. I didn't believe a raytracer to be feasible in Scratch at all, but then, look at this. Plus, the speed really isn't that bad at all, I still remember running POVRay in OS/2 and having to wait a full day or even more for a scene like this to complete....

08jackt 08jackt 1 year, 7 months ago

the pen size is at 25

Just as amazing... the artwork looks professionally done!

Longhair Longhair 1 year, 7 months ago

I know the first block! Pen down....

MITscratcher MITscratcher 1 year, 7 months ago

another brilliant creation of not only coding, but artwork! How can you do this? The coding is so complex, I wouldn't know where to start!
