Download the 19 sprites and 38 scripts of "Another Full Raytrac…" and open it in Scratch Project Notes
This is a full raytracer written in Scratch that supports ambient, diffuse, and phong lighting, light occlusion and a single level of reflection.
Running this program requires a lot of patience since it can take several hours to render the scene with the pen size set to 2.
This was a lot of fun to write. I think the Scratch team has done a wonderful job in developing such an extinsible language.

I downloaded and clicked the green flag and nothing happened
Are you still online? I do some 3D stuff at the moment. Help would be handy. Btw now with flash turbo mode your projects here are a charm!
I have uploaded a version that renders in hi-resolution, with the pen size set to 0.1. (link to project)
Cool!
What does it do??
paints a picture!
I reshared the project and made it compatible with 1.4. (link to project)
z so long - - z - z
cool
I made half the tags. :3
O.o THAT WAS WEIRD! I opened up the editor, and ALL THESE COMPLICATED SCRIPT THINGIES WERE THERE!
o.e I accidentally restarted it...
Yay! half the image has loaded and it's only been 3weeks!
LOL
Much faster in flash turbo.
renders in about 40 seconds with turbo flash
Incredible. Thit project doesn't run in my Scratch 1.4. Works in the Java Player, it is much faster in the Flash player but it is INCREDIBLY FAST in the Flash Player when run in turbo mode! (shift-click on the green flag). Excellent work Team!!!!!
I know, it's really great! The quality of it when the brush is set to 1 is also awesome.
(view all replies)Will this end? Oh wait........It has 1 more hour to do. I`ll run it in turbo speed then...Its done. Its great.
Click here to see the final render on pen size 1 (link to project)
LOL has COMMENT BLOCKZ!
here is a pic of it done on size one (link to project)
One setting ROCKS!!! (took me like three or four hours though)
im going to see how long 1 takes
cool!
sick and how u get pic by name
set it in turbo speed and it will do it way faster
Canthiar, describing you as "brilliant" really doesn't begin to cover it. You're a constant source of inspiration. Scratch on, man!
what does it do?
Seriously?
(view all replies)How I make it go?
1st comment since this got curated! What exactly is a ray tracer?
lower
(view all replies)Wicked.
This only took you a day! It would take me a year!
i cant really tell what it is at 25
lol i just left my pc running on pen size one and it worked.
lol
(view all replies)phong lighting?
It's a type of specular highlighting.
I set pen size to 1 and let my computer rest for 5 hours.. lol
AWSOMMMM! However I think you are wasting your time trying to do any 3d stuff in scratch. You can do it if you try really hard, but this takes a few hours, and making this same pictur using an application like Lightwave or Blender would take a few seconds.
thats true
I'm gonna stay up ALL NIGHT to watch it finish on ONE! MWA HA HA HA! >:D
this is also another full raytracer (link to project)
It's not a raytracer...
Perfect fidelity with pen size of 24! lol! ; )
Oh, I see. minutes. nevermind.
What does the "elapsed" variable use as a unit? Hours?
wow 3 hours?!?!?!? lol
i dont get it. what's it supposed to do?
draw a picture
My java isn't working, and offline, the main script of the tracer is producing an error. Any suggestions?
(view all replies)offline, remove all the comment blocks of the "ray" sprite and it should work.
Uhhh...what program are you running at what does your computer recomend to run?
All you should do is, go into the control pannel, un-install your current Java, then go to google, type in Java 6 update 15 download, download it, you have a working java!:D
(view all replies)Go through and delete them, it shouldn't take to long. They are only in the main tracer script.
AHHH I'm view 666! lol I'm atheist so idc.
it takes 4ev!
i don't get it... why do you need so many variables??? awesome though!
would it be poassible to remake this in scratch 1.3 and utalize the new features?
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.
(view all replies)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!
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.
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...
3/7
no, more like... 2/5ths
~1/3 done
Oh, I'm giving up on the online one. I'll just put it on 10 size and wait for a preview.
~1/4 of the way done (not online)
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?
already, it is ~1/5th of the way done! It is mostly just the floor right now, though...
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.
Project=God
Hey Canthiar would you like to be a reporter for bartshow magizine?
... wow... wow... wow... wow... this... is... amazing... did u tel it wat pic to draw at different sizes/FOV?
