Images Rendered New Unbiased Renderer -- Indigo // Work in Progress

Hey all,
I've been messing with this new unbiased rendering engine called Indigo and wanted to share. I'm currently exporting my models from truespace as .3ds and setting up the scene using a standalone tool i'm working on to generatel the XML to load into indigo.
Currently the renderer is still pretty slow, and not very feature-rich, but the materials and lighting are gorgeous. Because it uses spectral calculations to simulate the actual physical nature of light, not cached / photon mapped algorithms, etc., there's really no setup time at all to get the scenes looking nice. Anyway, let me know what you think!

Look here if you'd like to see some of the other images made with indigo, or to download it for yourself.

Really impressive renders!
On that first one - was the DOF achieved with the render engine, or was it a post effect?
Thanks for sharing this!

Hey Frank,
Thanks for the quick reply!
I forgot to mention that these were all straight out of indigo. No post processing except for maybe a quick levels in photoshop to lighten them up a bit.
Setup was basically 5 or 10 minutes -- Just one sunlight lighting the scene (the skylight is built into indigo to simulate real skylight).
DOF is based on two values, a Focus Distance and lens radius and is entirely implicit in the render. |

Very cool!
I will certainly have to read up some more on this renderer.
Thanks again! |

Now these aer just LOVELY. I saw them in the old forum just did not know how long they would be open. Glad you shared here. I too must look into this. I think I remember you stating the rendering times are long but I can wait...

Wow that looks good, I would like to see the render in truespace first though, so that the two can be compared? |

Thanks guys...
Hey Nephos: render times were around 7 hours. It's a progressive render, though, so you stop it whenever you like, and can always see it being refined. This really helps cut down on re-rendering, as you can pretty much see if there are issues with your scene in 2 minutes, then stop it and fix them before you let it cook over night.
Hemulin: I agree that it would be cool to see a comparison, but as I said above to Nephos, Indigo's progressive render makes setup so quick and easy that I'd be loathe to spend the time setting up and rendering over and over to get the setup right in truespace. These are all literally a model, 5-15 minute setup, and hit "go", with indigo. In truespace, i think to get a similar result i'd probably have to spend a day or two tweaking lighting, materials, etc. And you know that rendering that grass with TS really wouldn't be quick either :)
best,
roland |

OK, I see your point, it looks like a really good rendering engine though, i'm just about to try it myself; i'm surprised that it's free. |

Unbias renderers also have the nice little situation of being more phyiscally based. This meaning that Real Life cameras & lighting come into play very heavly.
Indio's neat but it's not going to be much more then an experimental render engine. |

Decent rendering for something that is free:) |

The progressive feature is neat but upon further reading I can see that it is an experimental render engine. So it will be fun to play with...

Yes, it's definately an experimental renderer, and not intended for production or anything like that. Who knows how far Nick will take it, but it is pretty cool to play with.
I got really sick of trying to get the perfect lighting /rendering setup with GI renderers, and don't really have the cash for maxwell render, so what the heck... |

I think I've read that VRay is capable of 'unbiased' rendering, but I guess it would mean being able to access some of the lower level VRay controls.

Hey all,
Here's a new image. This is straight out of indigo, just a quick levels to brighten it up a bit. Lighting setup was just a background light and all of the spheres are emissive (mesh lights). Took forever to render :)

hope you like it!

my focus is the modeling, how you have make the many different grasshalmes ? |

Hey Vizu,
The grass was modelled as swept up polys. I did about 20 different blades, then copied / rotated / scaled them around a bunch until there was a decent density. Then I made a group out of all of them and copied that & did the same thing. This way I was able to do a whole bunch of grass without too much hard work :) This scene ended up being around 550,000 tris.
Does that answer your question o.k.? I can post wires if you'd like.
cheers,
roland |

Criky if you making a couple of grass blades seems to be a pain but 20 , dont no how you people have the patience.
Nice Image mate:D :jumpy: |

Looks nice except every render has little specks of dust on them :) |

A lovely image - I'd be interested to see the same scene done in tS.... |

No one which could write an exporter from trueSpace to Indigo? :)
I play currently around with a 3dsmax to Indigo exporter and it works great! |

I dont know about you folks, but this is some of the most consistently realistic rendering I have seen!

Just has a natural quality, as opposed to the unnatural qualities we see in many 3D renders.. Still, the maths is just calculating the lighting very accurately and naturally hence so slow.. but no tricks needed! wow.... wonder if the engine would work quicker on a 2 quad core machine! |

why not. CPU speed can't be high enough :D |

I spent 11 hours rendering a very dull foggy ball with light coming from a hatch (caustic_participating_media_test.igs)..
It got to this point and is still going

hmm - this certainly needs some optimisation or another 20 years of computing power to evolve! Althopugh its actually only using 50% of the dual core processors most of the time..
Still - its nice someone started the process..
Update: it got to 18hrs and didnt look any different so I stopped it - thanks fro the heads up on that one Parva! |

:) looks nice.
Haven't tested indigo on a real multicore pc but my old p4 with ht is at full cpu load if I use 2 threads.
I find the image very clean and would stop at this point.
Unbiased renderer like indigo have theoretically no limited time in render. Means you can render ad infinitum.
Indeed optimations you can do in any render engine but for a free engine Indigo is very good. A tip render to a higher resolution (that smooth the noise if you rescale to lower resolution final picture) and/or use noise reduction programs.
Another thing is for the use of multicore cpu's, you can only use one thread and still work on the other.
Depends on the scene but agree it's nothing for impatient people :D
on the other site, unbiased renderer don't have much settings and you don't need long fine tuning processes. |
