Roman Theatre in Cartagena (Spain) Work in progress

Better earlier than later I think. The more you have the more you'll need to reverse!

pichuneke · 22 Dec 2007, 11:25

I am examining it, and I see that al the component has a texture, not "A face, a texture". Or something like that.

Must I begin to define every single face?

Gaieus · 22 Dec 2007, 11:29

Go to monochrome rendering mode to see whether you have front or back faces.
If they are components, even better; enter a component's context, select all the back faces and reverse them. All other instances will change along. Now use the material (again, on the front face) to paint it.

It does not matter whether you apply a material / texture on a back face; back faces are not good either way.

I oriented the faces in the inma cavea, (the blue area) and the problem persists:

I suposse it's a problem of materials in Kerkythea... I don't know

Pichu...
which render preset are u using??? try to use Photonmap medium + aa 0.3 preset.
lower presets can cause light leaks like the ones u showed here...
also try using the path tracing progressive preset if ur using just the physical sky.. takes longer time to render though.. i would suggest it only for the final images.

i assume u havnt made any changes in the materials???
i guess u better post this in the KT forum....

pichuneke · 22 Dec 2007, 15:54

Yes, I didn't make any changes to materials. I have no idea about this

I am looking for a solution in Google. As my english and knowledge are limited, I didn't know that the key word was "light leak". If I can't find anything, I will post my problem in Kerkythea Forums.

pichuneke · 23 Dec 2007, 15:26

Now I know that is a bug, but is not my fault. The light leaks appear under Photon Map mode, not with the others.

The images below show you what I say, under different presets.

PHOTON MAP FINE + AA 0.3

PHOTON MAP FINE + CAUSTICS + AA 0.3

RAY TRACING HIGH + AA 0.3

PATH TRACING HIGH + AA 0.3

After doing a quick test, Metropolis Light Transport seems to work well, too.

So now I am not nervous, and I know that I can continue with my work. I was doing it well.

I have tried to start a chorintian capital, that's what I have done untill now:

I used a photo of a capital (Gaeius, you know what I am talking about ).

I drew the figure over a photograph, and then I did something like a tutorial I can't find now, I used intersections to make it. And then I adjusted it manually.

The size now is 147 kb, but the photo is 55 ,kb. I believe I can use 500 kb for the entire capital.

pichuneke · 4 Jan 2008, 10:06

This is the actual situation of the capital:

about 230 kb

pichuneke · 5 Jan 2008, 16:53

About 290 kb:

pichuneke · 7 Jan 2008, 00:26

A render of the capital. It is almost finished, I have to work on some details yet.

The size is 371 kb at the moment

Gaieus · 7 Jan 2008, 01:43

And you were asking for tutorials on this!

Great job, really (just keep in mind to put these on a hidden layer while modelling).

pichuneke · 7 Jan 2008, 10:17

Well...

"Do or do not. There is not "try""

Gaieus · 7 Jan 2008, 10:57

I've put together a couple of types of the Ionic order (more or less complete) but haven't been able to create "easy-to-follow" tutorials from them yet.
They require external plugins (ruby scripts).

pichuneke · 7 Jan 2008, 11:06

Ionic Order is easier than corinthian, so I am not afraid now

If you are interested, when I finish the capitals I upload them here as an attachement.

I believe that today I will finish the corinthian column. And then I will have for my first time the known problem of "I want to replace this old component for this new one in the same geometrical position". I believe that is a classic...

Edit: the exact Ionic capital I need is "Italic Ionic". A friend of mine (the other model I told you) is looking for information about it.

Gaieus · 7 Jan 2008, 14:40

Yes there is a difference in the Greek Ionic and the Italian one (I mean the Roman interpretation of the classical Ionic order).

The problem in English language that they only have one word for this - "Ionic" (derivation of the Latin "Ionica") - which in Vitruvian use only refers to the Italian one.

The main dufference is that while the Greek loooks really like a scroll (so it it symmetrical from two sides and then another symmetry applies to the other two sides), the Italian is symmetrical from all 4 sides (has the shape of the abacus something like that of your Corinthian capital and the volutae torn in a bend to form similar scroll on the corners).

This was implemented by the Romans after the Greeks, too, however because on the corners of the temples the Greeks had to "cheat" as well. Now the Romans used these +cheated corners" for all 4 corners of their capitals and this way they can ba all alike.

But too many words - I should just make a couple of sketches instead...

pichuneke · 7 Jan 2008, 21:51

Due to my deep knowledge of Shakespeare's language, and to my superb capacity of comprehension... I haven't understood a single word, Gaieus

Yes, I believe that you are telling me that the greek Ionic is different from the roman Ionic, the roman one has a more elaborated capital. And I believe that I have seen that difference on the net (I can't remember where).

But this January I am going to have a lot of work, and all the big progress that you have seen this week is going to be slowed

So, be patient, please. The first thing I have to do is to investigate the famous single and eroded fragment of Ionic capital found in the area of the "Porticus in summa gradatione" in the roman theatre in Cartagena.

I am mixing latin with english and my brain is going to explode

So, be patient, please

Never mind, I know some Latin and at least I understand what you are writing.
