Download "Another Full Raytrac…"(19 sprites and 38 scripts) 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.

can you use multiple pens to speed up the process?

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

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.

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!

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!

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

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.

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....

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!
