To be clear, this scene is not an original idea by me. Here is a link to the scene which I based mine off of. However, the .blend provided there is not that great for blender, so I did my best to reproduce it. Hopefully there is no confusion

**********

Hey,


Well, after playing with a number of different renderers trying to create a realistic interior scene, I got the idea to model a scene and let each renderer show their stuff via a renderer challenge.

I've created a blender scene, complete with uv-mapped floor and paintings. The scene is fairly basic to keep the emphasis on lighting/rendering. With all the new renderers coming out of the woodwork, I think this is a great opportunity to compare/contrast the strenghts and weaknesses of each, including blender internal and yafray of course ;)

So, here are the basic guidelines:

1. The basic color scheme of the room should stay close to what it is. Adding nicer materials and bump/nor maps is fine, or slightly changing some colors to increase contrast is ok too. However, the "feel" of the room should remain unchanged for easy comparison between the different renders.

2. Post-pro should be kept to a minimum. We want to see what the renderer is capable of, not the Gimp/Photoshop.

3. You should maintain the same camera angle as is in the .blend file. This is very close to the vray render, and will keep consistency in the render.

4. Render size of 800x600 (let me know if you think this should be 1024x768)

5. Include details about the render, including light rig, render times, post pro done (if any), etc. The purpose of this challenge is for everyone to learn from each other, so let's not keep any secrets.

6. Time limit - none as of right now, but I think 2 weeks is a good target to keep things active.

Well, enough talk, here is a link to the scene, which includes the floor texture and the 3 painting textures. It also contains an image of the vray render I based the scene off of. I think the vray render is a great example of what we should be trying to achieve.

Well, I think that is about it. Good luck and good rendering!

PS - If a mod would like to move this to the "contests" forum, that would be greatly appreciated

[jendrzych]

i think defining bligatory image size: 800/600; 1027/768 or sth like that, would be helpfull for conclusive comparsions

[UglyMike]

Something along the lines of this (http://www.winosi.onlinehome.de/Gallery_t14_14.htm) but with a different/better scene?

[L13]

Hey i had an idea like this, but i was going to do it all myself and put it all in an article and submit to the CJ or something. When i went to look at doing this i was going to use Yafray, Sunflow, Indigo, Pov-Ray etc... but i had too many troubles trying to get indigo to work, and to get a decent result from sunflow. So i gave up. Glad to see you had the same great idea ;)

[RCRuiz]

Good, but I can not download the file . . band width problem. and an other thing we have to be clear about everyone use the same camera properties and resolution as jendrzych said.

Hi lakcaj
I think I found an error in your model. The last mirror ball holder is off. Is this intentionally, it don’t look like?! :-?

Hi lakcaj

heheh - no, not intentional. I was so tired when I decided to get this challenge started that I'm surprised I uploaded the right file at all :)


Well, here's a povray render I did:

render time: 30 minutes (was 4 hrs 50 mins)
radiosity setting: IndoorLQ (was IndoorHQ)
lighting: one point light and one area light outside the window, with a light yellow/orange (changed from light blue) background color for the radiosity - just changed the area light to have higher samples (thanks to RCRuiz in another thread)
changed: changed the black to dark grey and added a slight raymirror to bring out the definition in the chairs and coffee table. I also lowered all the material ambient settings to 0.0 for the radiosity, and increased the AA settings. I also removed "shadowless" for the lamp.

Some post pro done with gimp to adjust levels and increase saturation a bit.

where are the yafray and sunflow users? ;)

I was waiting to get more time to post something better, but here's my quick test with Sunflow. One area light and 6 bounce brute force path tracing (still noisy).

http://img372.imageshack.us/img372/9058/livingroom027mp.png

Obviously I didn't have time to match the lighting up to the reference. Too busy coding the next version =)

[RCRuiz]

fpsunflower, please put the rendering time

Now who is the brave one that have a couple of week to render it in WinOSi :D ?

[lakcaj]

fpsunflower,

I think that looks great, but I suspect you left out the render time for a reason ;)

Seriously though, I am very excited about sunflow. The only problem is it is a bit slow for my machine doing brute force path tracing GI. The shadows in that render look great, which is something I don't think povray does as well. Also, being a more "modern" renderer, I'm sure blurred reflections and things of that nature are not far off, or even available now. Actually, speaking of powerful java renderers, the Art of Illusion renderer is great and GPL:

[fpsunflower]

I think that looks great, but I suspect you left out the render time for a reason ;)


Thanks. Indeed the render time was about 2hrs on a dual xeon 2.4 although I was actively working on the machine while the render was going on. Still the rendertime is a bit long for a noisy image.

Brute force path tracing is gonna be slow no matter how optimized your renderer is. I'm about to start on a new unbiased engine for the next version that will hopefully be much faster.

Blurred reflections are supported and would look great on that wood floor, just didn't get time to tweak the shaders.

AOI is certainly is a very nice system.

[Lynx3d]

Yea plain path tracers will never break speed records on indoor scenes...no matter if they are called FPrime or whatever.

But i wonder what you could do with photon mapping in sunflow...or have you gave up on that already, fpsunflower?

And i need to write my renderer first :P

Alvaro,


Nice render. Although it does have some noise, it also seems to have a very nice range in colors . In particular, look at the chair backs - in your render, there is a nice progression of shades of black, where as in most of the other renders the chair backs are very black with a highlight.

Very interesting to see all these different renders - thanks everyone for taking the time to render the scene.

pd. now I know the importance on exposure so I include it on blend2Pov

OMG Alvaro that's a beautifull render and it looks awesome in POV!, 19 min on RCRuiz's crappy computer, that's impresive :-? RCRuiz add a SSS shader to the suzanne please!, like a candel :D

[RCRuiz]

the one of 11min it look as good as the 32 min . The conclusion of the test is that if I take a blend with a yafray configuration first I have to lower the samples (in the area light case) and then reduce te intensity of light at 25% more ore less. but now this is not in my computer at home . . is in a p4 3.2hrz :-?

11 minut's render looks a little noicy I think but if animation is stable that's absolutly ok, can you make some animation test with NO radiosity or photon baking, I got some friends here arguing that it's dificult to make stable renders in every engine including pov, they use mentalray btw, lets give them a lesson ;)

Hi every body
I think that this challenge shut have moor then one “winner”. I think one for speed and another for futures (blur reflections, Mattel shaders, sss ...etc.) and one for overall performance + quality. I say this because I got the feeling that some people here think that its al about speed.

Nice one Sonix!

Seeing that got me interested in seeing what could be done with the scanline renderer, so I downloaded the scene and tried it in Blender this evening.

Attached is a render where I got after about one hour of light/material tweaks:

http://blenderartists.org/forum/attachment.php?attachmentid=5642&stc=1&d=1147834188

3 area lights were used (near the ceiling/facing down, facing the scene, and left pointing into room)

An additional ray tracing, low energy (.2) omni lamp was placed in the same location of the ceiling area lamp.

Another omni lamp (diffuse only, .4 energy) was placed to the left of the chairs.

All lamps had a slight warm yellow tinge to them.

Materials were slightly tweaked: black was elevated to .170 for R/G/B; table and ornament were made slightly reflective.

Saturation was boosted internally in Blender. There was a slight hue shift also performed in Blender (-.20).

OSA was set to 8 with Cubic AA. I would have used CatRom for sharper results if I had time to render higher samples for everything.

Materials were set to FULL OSA.

AO "both" was used with 10 samples, a distance of 3.0, "use distances" activated with DistF at 5.0. AO energy was set to .8.

Pure Blender 2.40 optimized was used, internal scanline renderer only. No post-processing was necessary.

This took 19:26.97 to render on 2.13ghz Pentium-M laptop with 2GB of RAM, XP home edition.

I know I could have pushed it further in terms of matching up with the original reference render, better render quality, and light distribution, but I'm happy with the way this one turned out after the minimal effort.

Excellent idea these render challenges. We should have more of them :)

RobertT

[sonix]

Nice one Robertt. Very good use of the scanline render.


It does seem to be quite soft though, which is a tad weird for the scanline. Perhaps it's the shadows that are giving me this impression.

Nice work mate and I agree, more of these would be cool to do.

Sonix.

[RobertT]

Thanks, Sonix.

The softness comes from a combination of the lighting, AO, and Cubic AA.

It's always exciting to see how far Blender's internal scanline renderer can be pushed, especially in terms of render quality.

Here is the blend file (http://www.artofinterpretation.com/blenderfiles/livingroom.zip) in case anyone would like to check out my lighting setup, materials, and other settings.

Textures were not packed to keep the dl small, so just dl the original file from this thread to get those (only affects pictures hung on wall in room).

(Edit: Looks like the textures also affect the floor, so for a complete render do dl the original file for all the textures and use those).

I'm sure there are others here who are eager for another render challenge like this, so hopefully we'll get one soon :)

[droid42]

Hi all,

I know it's been a while since this thread was started but I've only just spotted it via the Sunflow gallery page.

So here's my first effort...

http://www.trackvids.co.uk/living_room.jpg

This is only the second public airing of my own all-Java ray tracer. Its first public outing at the beginning of this year resulted in a 3rd-placed still image in the IRTC "Fire and Ice" Jan/Feb round :D

The direct lighting is from 2 area lights ... the first is dim and shadowless (on the ceiling) and the second is bright and shadow-generating (outside the window). Both are pure-white in colour ... I wanted to see the contrast resulting from the cold, white light entering the window and the warm colour-bleed from the floor.

Global illumination is from photon mapping and a graduated sky sphere. Each lightsource generated 60,000 photons and 800 samples were taken at each pixel. I could have used the Ward irradiance cache to speed things up significantly but recently I've grown to dislike its "uneven plaster" effect that occurs on wide, flat surfaces. This, along with a glitch in my new non-uniform grid code (resulting in a 149x60x60 grid for only 84 objects, oops!) and other renders running in parallel, led to an approx. 14 hour render time on a 1Gb, 3.4GHz Pentiurm 4HT system. Without the NU-grid bug and busy PC it would probably have been in the region of 3-4 hours. If I'd also used the irradiance cache then a rough guess would be around 1.5-2 hours, maybe less.

I applied a bump-map to the floor, which is just the greyscale version of its texture map.

Anti-aliasing (adaptive) at 4 samples per pixel.

Intersection acceleration (or lack of, see above) is a uniform grid for each object exported from Blender and a non-uniform grid for the whole scene. I've found that the non-uniform grid can give significant speed-ups for sparsely/unevenly-distributed scenes but I'm still searching for the best strategy for automatically deciding the dimensions (does anyone have any papers/references for this?)

Any feedback appreciated. Can anyone spot the obvious global illumination bug in the image? ;)

Ian.

[lakcaj]

droid42,


Well done! I think that looks great. As for the GI bug, I'm not sure, but one thing that immediately caught my attention was the lack of shadows for the two ottomans. I'm sure this is because of the non-shadow producing light. Do you plan on releasing your renderer and blender export script? It's always fun to play with new render engines.

[droid42]

Thanks for the comments :)

That's not the bug I was thinking of ... the ceiling light was only there to add a little more cold light on the furniture and floor and not intended to add shadows to the scene (the ottomans are actually fully in shadow from the main light outside and any illumination they get on the back/legs is pure GI). However, you're right, they do look a little 2D...

I've been working on this renderer on and off for the best part of a year now. Almost all the key features were in place last year but a couple of months ago I did a mini-rewrite, mainly to get rid of defunct code and tighten up the interfaces. Since then I've spent the bulk of my efforts writing a decent GUI for it (including real-time walkthrough of the scene, drag/scale shapes in real-time, full preview and editing of materials/shaders/texture and bump maps, visual creation of full CSG objects etc.). So much more to do though, seems a never-ending task :eek:

Links to a couple of screenshots from the GUI as it currently stands...

http://www.trackvids.co.uk/screen01.jpg
http://www.trackvids.co.uk/screen02.jpg

I'm probably the only person who can usefully use it at the moment, although, having said that, it does have a Java/C-like scene description language (all the usual language conditionals, loops, functions etc.) so it wouldn't be hard for the beginner to use.

I've not touched the Blender export script for a few months now and I was quite surprised that it exported the above scene without any errors.

If enough people shout then I'll tidy up the UI, add any missing options into the SDL and release it as pre-Alpha at some point in the next couple of months ;)

Ian.
