Speed Modeling Challenge #58 - Optics.
--------------------------------------------------------------------------------

************************************************** *******
Rules:
1: Every week there will be a subject for you to model along with a time limit. You should spend no longer than the allocated time, then post a render of your model. As in most challenges like this, your honesty on modelling times is essential.
How you interpret the brief is up to you as long as the final model conforms to what is asked for.

2: Post a render of your model (min 800x600 pixels) in this thread with a wireframe.

3: LightWave should be used for modelling. 3rd party Plug ins are allowed.

4: You can enter as many times as you like, posting each in this thread. If you run over the time, the model can still be posted but won't be subject to the judging.

5: Time spent on texturing, setting up a scene for a render and rendering is not included in the allocated period.

**Please mention whether or not you would be happy to share the model.**

************************************************** *******
Lightwave Speed Modeling Group

Subject - Optics

A nice open one. Lenses, prisms, photographic equipment, glasses, drinks holders etc-imagination welcomed.
Lets see some Refraction!

Time Limit - 60 minutes.

Deadline - Wednesday, 7th October 2200 hrs GMT

Funnily enough I was trying to find the time to do a set of binoculars for the camping challenge,I might get a chance to do them for this one

Can I repost my opera glasses that I did way back when, near the beginning of these challenges? :D
I think it was a Victorian challenge or something like that.
Nah, just kidding.

I finally have a little free time, and hope to add something to this one. It's been too long since I last participated.

!w00t!

Hopefully I can find the time for this one, might mean I get to spoon on the refraction dispersion in heaps! ~8-D

Good show folks!
I've been really busy too and have some free time at last so I'm hoping to do some experimentation with caustics etc. Might even shake out my dusty copy of Maxwell for a play!

Is there a tutorial on refraction somewhere? Or will LW do it automatically if you provide the right conditions with objects, lighting and activate caustics?

Iain
10-01-2009, 07:28 AM
For refraction, you just input the correct refraction index for the material. Glass is usually rated at 1.51 or so but the trick is creating a thick object like a lens from a polygonal object that has no thickness.

The dielectric material does it well.

Caustics in LW is another matter :cursin:

A magnifying glass. Modeling took me about 25 minutes. This is a very nice render subject, but I'll probably mess it up. I'll work on it later.

EDIT: I just realized that I forgot to add microbevels, which I indended to add in the first place. I still had time left and I added them after posting this, they took me 10 minutes. Is it allowed?

AdamAvenali

i've never actually seen a tutorial for it, but what helped me with glass and refraction was learning a little about the science behind it. this site offers a nice little intro and also a pretty comprehensive list of refractive indices: http://interactagram.com/physics/optics/refraction/

You sure got that right.
I've found I usually have to crank the settings waaayyyy up to get anything reasonable. Although I really have to question whether it's accurate or not.

It took nearly the whole hour, mostly embedding the anchor into the lid of the box.
I will have a render soonish

Thanks Adam :)
I discovered something about caustics tonight, you can have them without using the caustic button.
If you use a HDRI or luminous polys for lighting, And in the GI panel turn on - use transparency and directional rays you will get the caustics as part of the GI solution.
I have not experimented with it much yet but it seems to work and with less of a time hit that the other caustics.
I haven't figured out how to get a nice sharp one yet but I`ll work on it.

It also needs to have trace refraction turned on.

A lot of you probably already knew this but it was news to me:D
It was about 50 seconds on my very old computer to render

Thank you both. Initially I started with radiosity, but ended up with 3 lights, area, point and a spotlight. The caustics button did not seem to affect anything at all. What's the secret? Also, thanks for the radiosity and caustics trick. I'll try it next time.

edit: forgive my butchering of the spelling above... lol....

Well I did a kaleidoscope, I guess that fits within the optics category...

About 45min on the modeling and then a bunch of time on the texturing and layout setup. This was the first time that I tried a linear workflow after watching Matt's video tutorial on the subject so I did spend a bunch of time adjusting different settings, etc. I used art's plugin for the wire render.

I'm not too crazy about the final leather texture so I might rework that at some point if I have time.

I haven't done a challenge in a while and it was nice to jump back in! :D

This sounds great! Would love to see what you could do with caustics in LW and Maxwell, maybe interesting comparison or something. Have been experimenting with this glass in different renderers. Am going to make a prismatic shaped one.

If you scaled down the texture on the leather by about 80% I think it would sell the leather look more

Richard, I'll give that a try!... if it doesn't look good then I might switch it out for a different leather. :)

Glendalough, those are very cool samples of caustics! I think I like the lux one the best. It's interesting to see how close the lux and the modo are though.

Its something about the shape of the glass, sort of squarish that gives more dramatic caustics than just a round glass.

On another forum I saw these spectacular caustics from a square glass, but the glass was so thin and had such a sharp lip that it couldn't practically exist in real life. Tried to find out if the guy who posted the renders designed it intentionally this way but couldn't get an answer.

Only get a faint light when using dielectric in Lightwave and very long render times (?) Maybe it worked better in 9.2

I've used the challenge to teach things to myself, but constant "demands" to my attention.... you know. One day we're gonna move into the forest.

Anyway the latest optic one got me to wonder if I can do a glass marble. Here's the result and is not what I want but I am on aNOTHER mission to see what I can come up with.

Anyway - you guys are inspiring.

Yes, very nice drop there! What's with the dispersion setting? Is this in the dielectric? You've done it subtly.

R.Feeney
10-05-2009, 05:54 PM
Ya its in the dielectric node, you turn on reflection blur and the you can set a percentage for dispersion. It also seems to be varied by the roughness setting/bump height.

R.Feeney
10-05-2009, 06:15 PM
Another one, this time a sniper scope.
It turned out quite messy in parts but it dosent show too much in the render.

That's interesting. A lot of render engines seem to have a parameter for this, but not sure how to use it, where it occurs, except in a prism. Mirror and metal reflections/refractions (?) seem to throw them out here and there.

R.Feeney
10-05-2009, 06:21 PM
In the real world the most obvious example would be a rainbow.
Or chromatic aberration in a camera lens. Always seems to be connected to extremely bright light or very high contrast

Just tried a different texture on the kaleidoscope.

That looks much better! For the purposes of composition, I'd personally rotate the camera up a smidge to the left and maybe move the lenses closer to the kaleidoscopes. Just an opinion.

Looks great though. Love the effect on the lenses.

Yes a lot of good stuff here! I like Art's laser experiment.

Managed to get a bit of caustic light out of 9.6, the absorption setting in dielectric can be tricky. Haven't got much to show only this obelisk run through the Crackit plugin, but it didn't do too much in the optics department except make a sort of pattern.

The obelisk came out pretty cool with crackit. I think the texture on it keeps you from seeing the actual cracks. Cool either way though!

I like that last one, Jeffry.

Simon, Lw just doesn't really hack it in the 'real physics' department. It has some great features but light dispersion and caustics effects aren't a strong point.

Just messing around with this one. (Should have subpatched the clock body).................

Just messing around with this one. (Should have subpatched the clock body).................

Thanks, Iain!

I thought that was Scooby Doo from the preview pic! That came out great too!

Heh, amazingly, I can actually spot the segmentation on the clock. :)

The obelisk came out pretty cool with crackit. I think the texture on it keeps you from seeing the actual cracks. Cool either way though!


I did one more version... don't ask me why...

The last version of your work has great lighting & surfaced best imho.

Here's the cracked obelisk with dielectric set to 100 dispersion. It takes just under 40 mins to calculate the "caustics", set to highest quality and then finishes in just a few more. Didn't really turn out too well though.

Used your node setup from another thread on this forum for the magnifying glass and added an ior (refraction index?), but not sure if this is done right either? As Iain says and i'm finding out, these physics parameters or whatever you call them are not strong points in the LW render engine. Oh well, maybe next time -9.7 special render engine upgrade edition.

oh yeah, I forgot about that node setup. :)

The obelisk looks much better now! you can really see the cracks in it, etc. Nice job on that version!

Ok after much deliberation, I've decided that even though the quality level was high throughout, as usual, Kuzey's bizarre steampunk goggle has to take first prize.
(The condition however, is that we have to get a render of it :) )

Congratulations Kuzey!

Honorable mentions to R.Feeney, Art and JeffreySG for some cracking models.

Did you tuen on LDR? Those hot spots look a bit too hot .. and that will mess with your antialiasing.

Nice nonetheless -

LDR= Limit Dynamic Range (?) Must try that. Thanks for the tip.



And Congratulations Kuzey, Great Work!

Kuzey,

Can you kick off this week's challenge?

If you are unable to someone else can do it for you.

Cheers
