Salem Capitol Lobby (Very Rough Draft)

This was mainly a bit of field research to see how many photos I should expect to dedicate to different parts of the building in order to come out to a satisfactory degree.

As with many of my tests, it was shot fast and sloppy. The white balance is way off, shots aren't level, shots are blurry from moving the camera when shooting, shots are horribly framed, etc. etc.

I'm encouraged, overall. I'll have to be more patient next time, obviously, but I wasn't sure that the majority of this was going to hang together. The parts that disintegrated are largely the fault of blur or of me cutting corners in my coverage where I shouldn't have.

The geometry is very simple here, but the complication is that everything is very shiny and very big. I'd like to integrate the front and back doors as well as the rest of the first floor, but I'm going to have to be very disciplined in which shots I choose because I have yet to see a synth succeed with 2000 or more good clear photos as input.

hey Nathanael, been busy? Thanks for giving a Western Capital to those on the East Coast.

I look through your synth feeling the well-known sense of a huge amount of accomplished work. First, the number of photos present here is amazing. Moreover, the number of individual objects you've chosen to circle speaks to your borderline obsession ;) with massive concave archs. I’d say, though, that your efforts pay off, mainly by creating an exceptionally clean 3D space.

To see how highly representative of the 3D space the point cloud is, I recommend (to future Viewers) using the "Overhead View.” You can see the walls and corners with such definition. Nathanael has made a blue print here. As expected, Nathanael’s methodology really “captures” the 3D space.

By the way, I also just found myself wandering around your synth looking for the "Rotational Arrows" because you put such an emphasis on these parts of your synths. For future viewers, the pillars, placards, and paintings are good examples of how to move around an object.

Oh, and future Viewers, please note the Capital Dome. It's awesome on this synth, incredibly 3D, and shot with a minimal number of photographs from a fair distance away. You may jump right to it by navigating to the last highlight of the synth. Great work on it, Nathanael! It’s incredibly rendered.

My other comment is that there are *not enough* pictures in this synth. Ha! At 1700+ photos this seems unlikely, but alas, it’s most certainly the case. With so many photos dedicated to rendering each individual object, the rest of the synth must remain somewhat thinly covered. Such is the nature of testing of course, but it underlines a fundamental tradeoff:

I feel that we’re entering an era with this software where we face a tradeoff situation of these two values. On one hand, I very much want to achieve the same level of 3Dimensionality that Nathanael reaches here, but on the other hand, I prefer the fluidity of motion that I work towards in my own synths. The easiest solution would be, of course, to combine these methodologies. In order to do so, however, we’ll need to find a way past the barriers in the number of photos that may be processed in a single synth or, as discussed elsewhere, find workarounds in Synth Linking, or other undiscovered solutions.

In any case, good work! Thanks for creating such an extensive synth! (The Captial Dome really blew me away)

Hey there! Thanks for the avid exploration and exclamation.

I totally relate to the feeling of, "...there are *not enough* pictures in this synth."... as you may well imagine. =)

The great thing about this building is that it is pretty nearly completely panelled in marble, giving each part a unique texture which the synther can quickly learn. The difficulty is that all light sources are reflected in the marble.

There's definitely part of me that looks at how densely the floor reconstructs when I barely glanced over it (like around the couches) and thinks to itself, "Hmm. Look at how easy it would be to build the entire floor and steps.". The enemy there is naturally the RAM limit. The best computer that I have at my disposal only has 4GB of RAM, running 64bit Windows 7.

I'm also curious to see what I would get if I shot only photos completely perpendicular to the walls except perhaps one orbit per corner.

The dome was a gamble, for sure. I had shot very nearly everything else at that point, if I'm remembering correctly, and felt like I should probably take it easy on any further shots inside this central lobby, but as soon as I saw the reconstruction, I wished that I'd taken more. I had some real doubt that Photosynth would be able to track it as it is largely symmetrical, but it did very well with what I gave it. I'll certainly have to take more care to connect all four corners to the dome next time.

Overhead view is very handy (especially for navigating quickly to a particular area), but for my more adventurous viewers, turning the photos off in the Direct3D viewer (use the [P] key) and using the [W] [A] [S] [D] keys to move around and [{] [L] [:] ["] keys to look around is hard to beat, as long as your video card has the right stuff.

You can use keyboard controls in the Silverlight viewer too, but it's not as fast + it turns off 1/2 the points while you move.

As a side note: others have said it elsewhere, but it's quite true and very funny that when shooting a synth like this you get some very inquisitive looks from your fellow human beings. People just don't know what to make of it or what can have come over you, especially if you're hurrying.

Four brave souls had the courage to approach me and ask me exactly why I was taking so many pictures and I happily gave them as brief an explanation as I thought they were after. Happily none of them were giving off an air of disapproval and|or attired in official looking security uniforms.

This is amazing! Overhead view is fantastic!
Good work! thx
