ArchiCAD 12 & Artlantis 2

Robert Fuchs — Thu, 11 May 2023 11:08:38 GMT

Hey, here is my first project with ArchiCAD12 and Artlantis 2.
I thought I would try a night shot. I love the filters that can be used on the renderings. I used the exposure option on these. I tried to use the neon shader for the car lights but Art2 would crash or lock up every time. I did get the shader on the light post but I couldn't change the shader color from bright white. So I still have a lot to learn with this new version but it is really nice. My Dual G5 2.0 just doesn't cut it anymore either. You really need to upgrade your hardware with this software upgrade.

What do you guys think?

Here is a second image.

Robert,

As always - fantastic images! Pretty much perfect in my eyes!

The composition is spot-on, as is the lighting.

I hope your bosses appreciate your talents!

Have you tried these without radiosity?

Certainly Artlantis having that preview eliminates the guesswork when arraying lights at night. The attached is one of my first night jobs, as they say down at the SkunkWorks - pre-dawn in Vancouver after a stormy night - gotta love that Artlantis sky. no radiosity makes it dark. BTW: SketchUP model.

But let me ask questions for my book - I am in the thick of it right now and wonder about:

- do you all have the fantasy of a dark sky? It rarely gets dark here because of street lights reacting against clouds,etc. this is part of night rendering...

- do users understand the "Golden hour" just before or after sunlight? This enlivens glazing to form the building against a sky.....

-- what am i not asking about that is important for night rendering?

Aah, like Magritte!

I was thinking of that scene in Fifty First Dates.

Peter thanks for your wonderful comments.

I will have to keep you in mind when it is review time here at the office.
Maybe you can put in a good word for me

Dwight, I have not tried these without radiosity. I didn't know you could turn it off in Art2. I will have to give that a try.

I would have to admit that I just recently started to look at photographs of projects we have done to get ideas on how lighting looks and reacts to materials and how the photographer framed the shot. I believe this has made the most improvement of my renderings so far.

I will tell you one thing about the night renderings I did. This was the first time we used a night rendering to show a client the reason for the design.
And the response was great. They loved the night renderings over the daytime shots. They had not seen anyone do it before.

Turning off Radiosity in the preview will set the preference for the rendering.

Depending on how you have customized your preview toolbar, the radiosity switch might not appear.

In setting up the rendering there are four levels of radiosity including "off", set in the rendering dialog.

Edit your toolbar and promote the radiosity switch to always appear.

In night shots, unradiositized surfaces will obviously be blacker and light will decay - i think that this is more realistic than the overly soft effects produced at night with radiosity. Artlantis will need to make a suite of dream characters with diaphinous nightgowns and white horned steeds if this keeps up.

Dwight, what glazing setting did you use for the windows in this amazing rendering?

Re: ArchiCAD 12 & Artlantis 2

Dwight — Thu, 02 Oct 2008 15:32:12 GMT

There's glass and diffused balcony glass.
But it is not the glass. The interplay between sun-just-below-horizon angled to reflect against the windows is what makes the scene.

And NO radiosity

Another version with more color in the sky.

Fantastic! More like paintings than renderings. How much time does it take for the settings?

Re: ArchiCAD 12 & Artlantis 2

Dwight — Fri, 03 Oct 2008 14:41:29 GMT

That's true. I'm trying to learn how to add colorful character. Radiosity makes night shots look too soft - unlike the nasty contrast you usually see at night.

You see the color since the sun is right at dawn, and I'm using the sky color and pollution factors to adjust the sky.

To make a 1500x1500 rendering was 7.5 hours on a 2x4x2.8 MacPro.
[Mainly due to the entire city block of 3D translucent trees adding polygons]

Yes, but when I asked I was experimenting to understand the Fresnel glass settings. I found the Fresnel transition value extremely sensitive and important - and I landed on precisely 0.3 like you did in this rendering. Also, reflection color is important. But smoothness seems to be less - at least for flat glass planes, it can be at min?

Re: ArchiCAD 12 & Artlantis 2

Dwight — Sat, 04 Oct 2008 08:16:30 GMT

Flat things are already smooth.

Smoothness affects the faceting of curved elements. If you see facets, you need more smoothness.

Play with the auto-detection -- exaggerate the irregularity of those panes with xy distortion is also useful in uniform glass facades.

If it is the trees, what trees are they? I routinely get 20 min to 1 h for daytime 2500x2500, high radiosity, high antialiasing, 6 city blocks with a zillion '3D Plants and Trees' from Abvent, detailed building models with lots of glass, a pond here and a pool there, same computer.

I never tried night renderings yet, with every presentation I start toying with the idea and then abandon at the feeling that they will need a lot of interior work and then a lot of lamp tweaking. What is the best way of introducing some sort of apartment-by-apartment or room-by-room on-off and light quality variations, if there is any other better way than a lot of lamps (like say would neon shader 'lamp' objects you can just stretch across some interior walls and slabs do a decent job?) Perhaps also some quick low polygon curtains (planes with translucent textures?).

Re: ArchiCAD 12 & Artlantis 2

Dwight — Sat, 04 Oct 2008 09:16:23 GMT

Those are custom Onyx Pro Trees with a buzzillion polygons each and translucent leaves. And about fifty light sources. Render THAT in an hour, buster!

I'm glad that you have asked about night rendering - I am writing that article in my book right now and will be sure to answer your questions.

Here is four hours.

It suffers from Little-Orphan-Annie syndrome - vacant circles for eyes [much like one might draw the souls of modern-day rappers] when you light interiors, you need stuff in there for detail. The Artlantis 3D posable animated "couple kissing" figures for instance.

The story of this image is sort-of like "The building stands proud, ready for occupancy having passed final wallboard inspection."

Shots like this need more light in the street.

This is so difficult. I threw a lot of lamps in there to see what happens. A zillion hours happen.
