Competition: A Slow Day (Closed)

[binarycortex]

Welcome one and all, a new LuxRender competition is upon us. The goal of these competitions is to showcase the capabilities of LuxRender and the community of LuxRender artists. We have another artistic competition that requires theme interpretation. The theme for this competition is "A Slow Day". This competition will run to May 31st 2012 23:59:59 UTC, at which time voting will commence.

Rules:
1. You must use LuxRender only, no SLG submissions. Use either the latest stable release, a weekly, or compile your own the day you start your render.
2. You must create a new original work, you cannot re-render something you have already done. Reusing old models, however, is acceptable. (A table here, a lamp there.)
3. You can use any modeling program/exporter you wish. (Yaay!) Just render in LuxRender (see rule #1).
4. Submissions should be rendered to at least 1000 S/px if possible. Carbonfluxing* a render is not necessary, but it makes them look very nice.
5. The only post production allowed is what is built in to LuxRender. (We are trying to showcase LuxRender, not Gimp or Photoshop.)
6. The time frame for this competition is 1 month. Submissions after May 31st 2012 23:59:59 UTC will not be considered.
7. The winner will be chosen by you via a forum poll.
8. Final submissions must be posted to the corresponding competition gallery.

Prizes:
1st place will receive a free license to the Reality exporter for Daz 3d
2nd place will receive $20 credit at BlenderRenders.com.
Runners up will receive a FREE copy of LuxRender and Blender.

Sponsors:

Notes:
*The term carbonfluxing refers to the fact that Carbonflux typically uses 10000 S/px as a minimum for a render. I.e. 1.0 CFU = 10000 S/px.

Nice! You, sir, have me a little bit stumped.

I'll come up with something though! Does anyone have any good ideas on how to achieve iridescence, as in hummingbird feathers, or butterfly/moth wings?

I was hoping you would chime in, you and a few others. (looks at past winners) I'm not sure I have anything for this as well. It is a rather open topic though. It could be anything, an empty McDonalds, reading a book by the fire, a picnic...however you interpret a slow day to be. I just had an idea, but I don't know if I can pull it off.

As for the iridescence, it would probably require a thin coating. So you may have to use a metal material. I know jeanphi had talked about being able to use the thin coating on all materials in the future, but iirc that was going to take a complete materials overhaul or something ridiculous like that. another possibility would be to use a texture and use that texture for metal, either straight up or as a mix.

A carpaint might be useful for different colours at different angles http://www.luxrender.net/wiki/LuxRender_Materials_CarPaint

my physics teacher came up with a solution to this one i think..

step 1:have an object(mesh) you want iridescence on (a butterfly wing) scale it to 200x size
2: create an regular octahedron
3: give each of the 8 faces a different color (metal textures?)
4: than have the program (blender) dot the mesh in a grid, as close together as possible,
5: make sure that the Octahedron's always keep the same orientation (they may not rotate with the mesh)
optional 6: scale the whole thing back down.

(he doesn't know anything about how blender or any 3d software works so this was the best way i could imagine it..)
so per 1cm^2 of mesh there should be around 1000000 Octahedron's.
i think you could use something like a sphere or some other object and give it a gradient of colors to each face.


i think i'm going to see if this would work. (i will take a lot of ram!)

Nice! That sounds like a very interesting solution. This basically achieves rough normal-based shading. I wonder if I can make this work somehow. If not, I might just have to paint it on, counting on a static camera angle. Thanks for the suggestion!

Not neccessarily. You could instance the octahedrons (like with a particle system, for example).

By the way, I'm in, too
I first wondered if I could come up with an idea to that topic, but the ideas soon came to me... as always, your choice of the competition theme is great, Ian! Much artistic freedom and space for interpretation - I wonder what others will make out of this topic.

I love that you had a plethora of ideas, i wish i had one...

Hello everyone

I've been working on one scene lately and it seems to fit in with the theme, so I decided to participate. Since I'm new here I would like to make sure I'm doing this right; basically I have to upload the render to "A Slow Day" gallery?

Yep:

8. Final submissions must be posted to the corresponding competition gallery.
