Nvidia Fermi Octane Competition (CLOSED)

[havensole]

Dont forget to optimize your meshes as well. I can't remember completely how overly complex one of my scenes was for the firt competition, but I remember running into a lot of crashes and such with overloading the memory. Simply finding ways to remove un-needed polys can do wonders. Simple things like asking yourself if that circle needs 32 polys on it's edge, or can you get away with 24. A lot of this depends on your particular scene. Basically it all comes down to simplifying everything. Using simpler image maps with a good hdri and some filters can look a lot better then detailed maps and no hdri. What card are you using by the way?

That's good to hear Radiance. It would not be fair for lechu's stuff to be taken off. If he wins, he deserves it. If someone else wins, they deserve it.

havensole I have GF8600GT, optimize mesh yes, but I also done this before, my Uboat orginaly have about 1.2 mln polys. In Octane I put version with 200 000, I' m thinking about new GPU at the moment, because I care to finish this scene exactly in Octane, priority not for win the competition but to support Octane.
Cheers dudes!

hi mib.
alpha map does not work with sunlight yet ,i hope radiance will fix that soon ,the same with glass , the sunlight passes not
trough the glass ?? does two things are absolut importend for archviz.
by the way my plants are mostly geometry exept the ivy ,if you render with path tracing the issue with the shadow
is not so visible .
cheers

Hey,

you'll just have to make hay with what beta2 has

most of these issues that are missing in beta2, area lights, sunlight through glass and alpha, are things that require laborious code that is not needed anymore when we have MLT, so it makes more sense for me to work on MLT instead.

That's my priority for the next update, MLT (which will automagically add those missing things), and multi-GPU rendering.

Hi, I am back with a new entry. I'm very happy, beside the fact that I have forgotten to apply UV coordinates on some (not visible on this image) objects. This means that I will have less possibilities to move in the scene. I hope that I will be able to reload the obj without loosing my materials settings !

I'm happy, because at the price of one level of subdivision and one level of multiresolution, I have been able to include in my scene the character on which I was working hard for three weeks.

On my 8800 GTS 512, I am at the dangerous limit of 65% of my 511 MB, with 366.4 MB used and 781303 Triangles ! Everything is very slow, and I have to work only with one screen, but it works. I have noticed a problem with the color picker that refuse to work after zooming with Ctrl+Scroll wheel. Verified 3 times, and had to exit and reload 3 times. So I take care of not touching the Ctrl key ! Do not believe the counter at the bottom of the proof screen : hours have not been displayed, and this render took around 4h30 !

Octane has really winded up the spring of my imagination and given a new start to my old sleeping project "Flying Circus". I thought I would never continue it, because I couldn't achieve the visual quality I wanted. The most difficult part for me was to model and rig a character, because I had never done something realistic enough in that area previously. Octane competition gave me the urge and energy for that. Thank you !

So, let me introduce Elisabeth Warfield. She is around thirty years old. Elisabeth is an experienced aerobatics pilot. Her grand father and his best friend were in the US Airforce during the second world war. back to the civilian life, they founded the Wild Geese Flying Circus.
Elisabeth began to pilot near the age when other children were starting riding a bicycle.

Now, she is an aerobatics instructor and a specialist of aerial photography. Her prefered airplane is the "Red Goose". Elisabeth and her father have built it from scratch starting from a Wright Cyclone 9 motor found in a airplane graveyard. Her father took hundreds of photos of her beside this biplane , during the construction.

Nice model, but it deserves a better composition for sure.
Also, its very dark ( gamma issue? )

[ROUBAL]

Dark ? It is very bright on my screen ! I even not used the Pathtracing because the image was too dark in background.

Have you checked your monitor ?

[[gk]]

Ill take photos of my work monitors and print your image and take photos of them when I get to work.
And when that is done I will talk abit about those images and possibly compare them to other images and state my findings in a followed post here.

[ROUBAL]

Wow, so much work ! I think that it is only a difference between what each of us expects from an image. I try to keep a balance between dark and bright areas. I used the sunlight, at 11h in east Canada, and the sun is high, so there is a lot of shadow right under the airplane. I used direct lighting because the inside of the hangar was really too dark, I find that the background is a bit over lit, but it is difficult to put some light inside otherwise that making a hole in the roof of the hangar.

For people who have problems with fireflies, I use a very simple and efficient method to remove them without noticeable sharpness loss. Denoising softwares blur the pixel inside a given radius, and this leads to a loss of definition.

Removing the fireflies with a one pixel clone pencil is very tedious as you have to aim in close up on a ixel close to the firefliy and then paste it on the firefly.

Here is my prefered method: In photoshop or your prefered image editing software, put your image on a layer and duplicate it on the layer above. Apply the "dust cleaner" filter on the lowest layer. Then select the eraser and set it to a radius of 4 pixels with a power of 100% and a smooth influence. On, the upper layer, just click on each fireflie. This makes a hole in the high layer and removes the firefly, revealing the cleaned layer. As there are only holes here and there, the treatment is applied only where needed without blurring the whole image.
Flatten the image and it is done!

Hi James, Nice image. I have had to use Firefox to display it. I usually use IE7, but you uploaded a png image that seems to be not viewable with IE7.

Your image is not displayed in the post under IE7 : I see just a small red cross instead.

A jpg image would be better.
