Yup. Actually getting close to done...all I really need to do is lighting and a few touch ups and I should be good. I'll post pictures soon.

Cool! big_smile Can't wait to see it.

jji7skyline · 2012-10-20 06:14:55

awesome :3

technoguyx · 2012-10-20 12:27:28

Oh, awesome. I'm currently learning Java, I really should start learning to use graphics libraries. Maybe LWJGL.

Mind releasing the source code? It could help me eventually ;P

Well...I can refer you to the video I found about rendering pixels in a window using JFrame...since I'm making my ray tracer able to trace almost any shape, it'd be a little hard to release all of it cuz it's a lot.

Oh, okay then. Anything helps wink

Basic Rendering (Just intersection):

Time Rednering (Based off the time it takes the ray to get to the object + some ambient light):

As you can see, time-based rendering looks a lot nicer. smile

technoguyx · 2012-10-20 13:16:06

Much nicer, indeed. Longer time (which I suppose is the distance between the ray's origin and it's intersection with the object) = darker?

slinger · 2012-10-20 13:39:18

Wow, nice!

Yep! But there are limits on either side. The maximum limit on the brightness is 1 (because that's the highest float that can be taken so otherwise it would take the remainder which doesn't look good) and the minimum is the ambient light present (I believe I used .1).

Lighting Update:

Still not perfect but looks a lot better!

wow! It's going to be awhile before I understand what math goes into it... How long did it take to render the image?

technoguyx · 2012-10-21 23:37:58

Wow, awesome. big_smile The specular looks a bit big, though tongue

Also,

Not long at all....you can almost do real-time rendering. Here's the vid: https://www.scratch.mit.edu/ext/youtube … ata_player

I can't seem to view the video hmm

technoguyx · 2012-10-23 09:30:33

Can't seem to, either... lemme try

EDIT: That works c:
