Follow the path of light (Simple is Beautiful)

[neo2068]

Hi!
Finally I found some time to do a render for the contest, too. It uses Hoodedman's laser ies light (from J the Ninja, http://www.luxrender.net/forum/viewtopic.php?f=36&t=6485#p66844 ) and a set of glass tubes with a scattering interior media for the letters and a simple glossy emitting material for the logo. The laser light bounces through the tubes and generate some nice caustics. The current image has about 3kS/s but it is still rendering.

Here are the different light groups:

logo

blue laser

red laser

Ooohhh shit! This is just freaking uber awesome!!1

Holy crap! That's amazing!!

I would hold your breath for now folks and wait for the final copy I think you'll find there will be considerably more patterning along the letters tan we can see now as the light refracts it's way though the glassy mediums - then it Will be truly something to behold - light itself in motion!
An excellent concept I look forward to seeing how it develops as the details are filled in by the render.

DAMN! O_O

The bouncing pathes didn't get visible as strong as expected. This is the final render for the contest(~ 6kS/p).

Then I rearranged the setup and raised the scattering value of the glass media. Here is an update with the new settings.

neo2068, this is amazing work,
i second what hoodedmanwithsythe wrote - the light paths inside LUX letters are just totally sweet.

Are the LUX letters forward scattering mediums?

That must be some heavy computation task to get caustics in SSS

I didn't change the g value, so it is isotropic scattering. Perhaps a different setting would have been better. I don't have any experience with that. Actually, the rendering is quite fast with the ies light sources. I get 34 kS/s on my little 'renderfarm' (1x i7 860, 1x Core2Duo T7300 Notebook, 1x AMD Athlon 64 X2 3800+).
