Re: Some examples using the indirect light
Thanks for posting these images smile

It would be very nice if you indicate how much time it took to render these images with your settings, and even better, with default Sweet Home 3D settings. It could help to evaluate if it might worth it to make some improvements in Sweet Home 3D.

Re: Some examples using the indirect light
Ideally we would need:

A plug-in that:
a - allows to play with the render settings AND
b - renders a file and reports the duration of the render
Both features are available now, but in separate plug-ins.

Standard files that could be used for these experiments. These files should be designed to include "problem areas" such as white specks, transparency, shininess, etc.

I would be happy to run a large number of tests.

Re: Some examples using the indirect light

It would be very nice if you indicate how much time it took to render these images with your settings, and even better, with default Sweet Home 3D settings.

In the previous post, I added in blue my settings and the rendering times. I use a computer with only 2 cores.

Common default settings for quality 4 :
causticsPhotons=0, shininessShader=default, normalLens.focusDistance=250, normalLens.radius=1
filter=blackman-harris, samplerAlgorithm=bucket

Photo made in 512x288 pixels.

SweetHome3DExample4

rendering time : 6min 59.77s (aAmin 1, aAmax 2, gI default, dB 1)
SweetHome3DExample4

rendering time : 2h 53min 44.64s (aAmin 1, aAmax 2, gI path, dB 2)

By reducing antialiasing values, rendering time is shorter.

SweetHome3DExample5

rendering time : 8min 8.78s (aAmin 1, aAmax 2, gI default, dB 1)
SweetHome3DExample5

rendering time : 43min 14.76s (aAmin 0, aAmax 1, gI path, dB 2)

SweetHome3DExample5

rendering time : 7min 14.52s (aAmin 1, aAmax 2, gI default, dB 1)
SweetHome3DExample5

rendering time : 15min 34.32s (aAmin 0, aAmax 1, gI path, dB 2)

I had thought to integrate advanced settings in the default photo panel but it was not possible at the time.
Now there is a new photo plug-in, it might be feasible for a future release. We could add a button to open a dialog box displaying the photo renderer properties related to the quality indicated by the slider.

Re: Some examples using the indirect light
Hi enkonyito thanks for this forum here
I made my experiment here /maybe good for some users/... /photo of cousin's house/

I try to compare IPR algorythm to BUCKET algorythm /INTEL CORE i3-5010 combinet with NVIDIA GEFORCE 930M graphic cards/

settings IPR image
AA min2
AA max4
GI default
sS silk
algorithm IPR
filter blackman harris
pic size 3500x2333px....then resized to 1500x1000px
time rendering..2hours 5minutes

benefits: short rendering time,simple algorithm able to rendered complicated scenes /for me very good for exterior scenes with GI path settings/
disadvantages:"plain final projection",significant shines reduction,very big size of final picture which need to be reduced

settings BUCKET image
AA min2
AA max4
GI default
sS silk
algorithm BUCKET
filter blackman harris
pic size 1100x733px then changed to 1500x1000px
/the same settings as previous. I changed algorithm and pic size only/
time rendering 7hours 50minutes

benefits:plastic and realistic final view /the difference is significant on big screen/,small final picture size, /for me good for interior images/
disadvantages:very long rendering time,sometimes troubles with more complicated scenes

love these experiments smile

Re: Some examples using the indirect light
@MartinSK

I try to compare IPR algorythm to BUCKET algorythm ...

I do not know if you've noticed but from my tests, for IPR algorithm there is no anti-aliasing applied. As for multipass algorithm there seems to be a pre-defined anti-aliasing.

I know that my experiment is not about indirect light ...

If you still have the same problem , you could send me your file so that I take a look.

Re: Some examples using the indirect light
Hi @enkonyito.
My problem with path is resolved.
I was not sure about antialiasing in IPR...But I saw that I can't see any changes when I experimented with AA in IPR.
Please can you explain me the real difference between multipass and bucket except pre-defined antialiasing? I read something but I am not sure if I understand it. And what is the pre-defined AA in multipass?
And the last question...If you can tell- what's your favourite filter?
If you don't want to write here you can send me PM. Thanx
Martin

Re: Some examples using the indirect light
Hi Martin.

My problem with path is resolved.

Glad to hear it. smile

You could perhaps show us what happens in this project or another. wink

Please can you explain me the real difference between multipass and bucket except pre-defined antialiasing? ... And what is the pre-defined AA in multipass?

Hmm, good question. I have not found this info even in the source code of Sunflow .

And the last question...If you can tell- what's your favourite filter?

My favorite filter is Mitchell. I found that some filters use a blur more or less pronounced compared to others.
Here is a ranking based on the visual differences:
1_ blackman-harris, bspline
2_ gaussian
3_ mitchell
4_ triangle
5_ catmull-rom
6_ sinc
7_ lanczos
8_ box (anti-aliasing ignored)

Re: Some examples using the indirect light
@enkonyito

The ChangeLog for SunFlow 0.7.3 mentions the multipass renderer *isn't* an actual multipass renderer, yet -- which may explain some of the confusion. wink

Re: Some examples using the indirect light
Hi @enkonyito
Here I have some experimental pictures using indirect light for an external view. Just for try different settings. Here is the first one I made this summer without using indirect light.
settings ...GI=default,DB=1

Now I came back and try to made the similar scene with indirect light setting....
sA=bucket
filter=bspline
AAmin=1
AAmax=1
GI=PATH
DB=2
sS=silk
size 4000x2667px...then resized to 1000x667px
/you can see that roof is not super antialiased biggrin

/ but the picture "look" is really different...I can only say that for my personal feeling it is too much color there but sure you can change it in postprodiction

and here I have the third one...
sA=IPR
GI=PATH
DB=1
sS=silk
but I use setting "enhanced external brightness" and then enhanced the highlights in postproduction /only for try/ and the result is here
size 7000x4667px...then resized to 1000x667px

I didn't want to post the third image here cause I changed it for a little in postproduction but for me it looks most natural smile

...not sure if it is interesting for you or for other users but for me it is nice exhibition how different can the same scene be with using different 1.3.1 settings

Posted by bdfd at Sep 22, 2016, 6:01:55 PM

Re: Some examples using the indirect light
Surely, I prefer the third ! applause

Re: Some examples using the indirect light
I also find that the rendering of the 3rd image is best. Nice work Martin!

...not sure if it is interesting for you or for other users but for me it is nice exhibition how different can the same scene be...

As you can see here , some users are interested in this kind of test. It would be possible to create a thread dedicated to it.

Here is another example of interior.
SweetHome3DExample7 (aAmax:0, gI:path, dB:2, 1200x900 pixels rezised to 600x450)

rendering time: 1h 25min 20.9s

rendering time: 3h 51min 24.8s
To reduce the picture noise, increase the number of anti-aliasing and/or pixels.

Hi Mike,

Here , you can get more info.
At first, I advise you to test with sunlight only to compare with the "reality" and uses diffused bounces 1 or 2 to not have rendering too long.

Re: Some examples using the indirect light
here are mine experiments by indirect illumination..../bathroom in 50's style/.... all pictures made by IPR rendering.... 6000x4000 pixels....then resized to 1000x667 pixels
rendering time from 12 to 14 hours....by slow graphic card
for me indirect light technique looks really realistic....the only one problem is rendering time for slow comp of-course....but I start to prefer it more than "default" setting

Re: Some examples using the indirect light
@Aeowyn....I publish these pictures here because were made by indirect illumination rendering....the design is not the main topic here...
I made this bathroom for real woman, for real place and for real situation in very little bathroom in flat built in 50's...
It is full of compromises...that is real life,not fantasy project where everything is perfect and ideal....
That machines are central gas boiler and little wash-machine. There's no other space for that machines in little flat... So I try to made gray glass panel for a separate illusion of these machines to the rest of bathroom. And that design and colors I made by request of customer in style of 50's... I watch a lot of 50's designs to made this bathroom most authentic.... It is not my favorite style but the customer was very happy because she loves this style. It was a good experience for me.....
@Aeowyn I know that you don't like my designs and I accept it but you forget one think here....and it is that designer made his designs by request of customers and have to resolve lot's of not very ideal configuration of electricity,gas configuration and the finance of customer...

Alrighty... I don't understand where that came from... all I did was ask a simple question... Thank you very much for answering it... I'm fine with why these pictures are published...

Hi Aeowyn, I for one have never perceived your posts as anything but constructive and positive - and certainly not upsetting. And that includes your comments in thread 5766. So as far as I am concerned, there is absolutely no reason for you to ..step back from whatever is going on... smile

Re: Some examples using the indirect light
I said again sorry.
May be it's because English is not my native language and some words or grammar constructions sounds a little different for you and for me.

Re: Some examples using the indirect light
Aeowyn, I hope you won't leave this place.
I guess it was simply some kind of misunderstanding. Don't forget that most of us aren't English natives and/or don't live in an English speaking country. This inevitably creates some misunderstandings from time to time, but differences in cultures help also to get more diversity in contributions and ideas. smile

The purpose of this thread is to show the use of the path tracing in SH3D.
As my computer has only 2 cores, my setup is a compromise between time and quality.
To compare, you can download the examples in the gallery and do tests with your own settings.

Sweet Home 3D is not a software for calculating the sunshine of a building or the amount of natural light in a room.
You can still get a glimpse using the indirect light rendering (GI: path) and the enhancement of the external brightness.

The photos of the chalet were taken on January 1st, 2019 in France. It is always possible to improve them in post-production in an image editor.

Personally, I prefer to stay true to the natural brightness of the room which will therefore be more or less dark.
