realistic sun in AC10

Realistic sun in AC10 works very similar with heaven light.
Is it right?

The realistic sun is the easiest way to get soft light in ArchiCAD 10.

The supplement to my book covers this exciting development in detail.

BTW: There's no sun in heaven. In heaven, it is all diffused cloud light to not cause glare on your harp.

It looks like almost Radiosity...
We should devolope our skill with LW, because the policy with Artl. I am not satisfied (no Artl.datei for AC10!!)

@Dwight:
Please explain sometimes also hier except your book

Sure it IS better, but saying that the new sun effect is "almost" radiosity is like saying, after a guy tries to leap a moat filled with leaping, snapping alligators, that he "almost" made it.
You obviously aren't studying radiosity renderings to understand the subtle reflected light energy in a radiosity rendering that translates reflected color and luminosity from one surface to another and general incidental light energy with controlled decay that makes a radiosity rendering worth the wait.

As for my book: if you want to get the ArchiCAD 10 supplement, it is only going to be available to registered owners of my book "LightWorks in ArchiCAD." This book can be ordered directly from me as said below.

The supplement will cover the three salient - and undocumented by Graphisoft - changes in ArchiCAD 10:

1: The new built-in sun shader:

This has a great imapct on rendering quality and replaces the Sun Object as a stand-in for Sol. The Sun Object is relegated to the infamous Undersun role.

2: New surface and environment shaders:

There are some important additions, vomit splatter among them.

3: Incidental UI changes and their meaning.

Some dialog boxes look and work a little different[ly].

These changes don't supplant the usefulness of the book, so even if you are only interested in the changes for ArchiCAD 10, it is worth your while to get the whole shebang.

Thanks Dwight.

We can do this way with LW and with realistic sun.
We dont need any other rendering programm.
Just we need some more people bitmap from lib.
Plants are now better.

And without this seeming like a plug for tree modeler Onyx Tree Pro, with the LightWorks engine using both processors, reasonably complex 3D trees can be rendered in a fair time period.

BTW: Abvent is supplying the export plugin for their current Artlantis. I hope that is good enough - anyone currently using Artlantis 4.5 would be an idiot not to upgrade, so that lack of old version support is irrelevant.

This is absolutly bad....I am using Artl.4.5.
I must save first as AC 9, than save for Artl.4.5...

If you save from AC10 as AC9 and you are using AC10 Library Parts, you will lose them in the resulting AC 9 file, so you will not be able to create the same 3D Model to save as Artlantis from.
You should watch out for this.

In AC 10 also check out the realistic sky shader. It can be found in the Library:
Lights, LightWorks Lights, Sky Object, in the settings at Sky Object Type choose Realistc.

I see what Dwight means about the crocodiles. The soft shadows are nice but they sure ain't no radiosity.

Than I must save as 3D-Studio. In this case the scale will be very confused.

I can recognise the difference betw. sky object and realistic sun.
Here is the test with realistic sun, the nummber of samples are 300

Of course, now we have them in a trap.

If, after a year, they are finally getting around to implementing something they call "realistic," what did we have before?

I guess we'd call it "PhotoCartoonistic."
"PhotoFakeist?"
"PhotoRushedItOuttheDoorBecauseWeDidn'tHaveTime to FinishtheShaderCode-ButMaybeIntheNextRelease?"

Could some others please confirm in what trading areas on Earth the Sky Object wirh Realistic option is provided?

Or is it just the Germans who get it before the rest of us, again?

My USA version Sky Object looks the same as last time.

I'm sorry guys, but I have not found any changes between AC10 skyobject and AC9 skyobject. I don't even see any new parameter for realistic sky and i don't see any quality improvment with the same settings in the 2 versions. I've just install AC10 (run in demo) but there is not a single paramter and changes in it. What object are you talkin about. Do i miss something here?

You can find out realistic sun in photorealistic parameter:
in LW-environment
There are two options, one is sun, the other one is realistic sun.

Sorry your USA version is ok.
I mean realistic sun in in photo realistic parameter.

Why so stupid names....It would be called...softy sun or such like that...

Check that you've got the right library loaded. Some have reported that AC10 sometimes loses track of its History in Library manager.

My Ac10 INT build 817 library has a new Sky object (new symbol, Now With Name) where you can choose btw Quick and Realistic options. When R is chosen, the list of parameters shrinks considerably. I'm looking forward to your supplement!

Also, the Lightworks Rendering Settings has a setting for Realistic Sun, the parameter list shrinks there too.

But I didn't find a Sun Object in the AC10 library. The one I have is AC9's. Guess if you just have AC10 and want an Undersun, you'll have to configure a Parallell Lamp for it.

Re: realistic sun in AC10

RE: Undersun

All the lamps have finite operating distances. ONLY the SunObject can do the Undersun for large distances.
