This is pretty damn cool!

Thank you sir. Here is another update.

Capitals are finished, dome shell is up.

Lower level nearly finished.

Some more progress shots.

Old black and white picture from similar angle for comparison

The two arches are place holders, I was experimenting with twisting its profile as it rises from its base. Feel free to share any tips or ideas on how to build it and make look smoother.

Hu, and I thought this thread was dead.

Well, I wasn't idle this whole time. I went back and developed the geometric studies even further. Here's a test print showing plan and section studies.

The columns came out a little funny but it is still a work in progress.

I've also restarted the model, this time based of the more detailed geometric studies.

Here are a couple of progress shots after a couple of days' worth of work.

Is this book available for sale? Who wrote it?

Great modelling!

Thank you sir. About the book, funny you should mention that. A friend of mine has been encouraging me to put all of these studies and models in a book. So, it isn't for sale yet but it is in the works.

Hi gdbalck,
I'm an italian student of architecture, I saw your S.Carlo alle quattro fontane's model. I'm writing my thesis about the light in this church. Should it be possible to receive a copy of your model or just any views of the inside? I can imagine the hard work to create the model, so if it is necessary I can pay you (if you don't want too much money ) bye bye.

Do you still need this? Feel free to contact me via private message here on the forums, I'd be happy to help you.

Update:

Borromini's Capital

Quick render without materials next to actual column at San Carlino.

Since June I've been splitting time between studying the plan and column geometries. You might say, why not just grab one form the 3d warehouse. This was a consideration until I learned that Borromini had done something very unorthodox at San Carlino. He inverted the volute of his composite columns under the arches. Well, I couldn't just grab someone random column to put in the model knowing this.
After much labor and effort, here it is. A couple of things are missing, all of them ornamental. I'm not sure if that's something that can be taken care of with textures.

Thanks dale.

I've refined my geometric studies of the plan even further over the past few weeks. I've also added a slight flare in order to help them look a bit more "authentic" to the time period

For your viewing pleasure.

I'll be working on the sections next before proceeding with the full model.

I've been working on and off on this project, it takes a lot of brain power! Most of the time has been spend on geometric studies of the half domes. The latest lead to the image below.

I've spent the last week doing more in depth geometric studies of the building before starting the final model. Here are a plan and a section study.

Ha, yes I've been lurking around for almost two years There's just so much information here that I read mostly, well always really.

Thanks leedeetee, here are some more images from the Twilight thread.

View up to the dome, the main altar is to the right. The Lantern is yet to be done.
