Urgent : turn photos into 3D landscape // Roundtable

A client is asking me to build a landscape scene (industrial site) from helicopter photos. The goal is to make an animation of the current state to a future project (like drawing new buildings, removing some old ones, adding trees, car parks, etc...)
Do you know some program that could process the photos, and output a 3D scene mapped with the bitmap from the photos, I could load in trueSpace ? |

every cg program with photo- or cameramapping should do that.
Maybe first stitching all photos together to get 4 or more area bitmaps.
Then creating the geometry based upon the photos (not very accurate of course but currently I don't know a better way. Landscape side looks more difficult as room - for rooms I had seen this already) and apply the bitmaps via camera mapping to the surface.
Just an idea... |

yes adrianis link to photosynth would be a software that can generate (pseudo) 3d from photos.
But I doubt that it's currently possible to export the generated pointcloud to vertices and to 3d models. |

hi Friend Parva,
Yes, I doubt too, but the photomodeler is maybe help

I beleive SketchUp Photo Match tool is very simple and effective way to do this. Here is video tutorial http://www.youtube.com/watch?v=fSuDoX8SPtU |

Depending on your budget, there are maqny programs that can do that.
Sketchup works well from overhead photos. I can list the steps if needed.
You will also need side views, 3/4 views and closeup detail of any areas you plan to focus into... You can also do more than you think in TS. There is a thread in these forums started by 3D dude that shows some of them...
Software to consider
Sketchup
ImageModeler
Photomodeler
These are the best of the standalone programs for this type of work that I know of. Also C4D has new camera mapping tools that go a long way to do this also.
The program you choose will depend on how quickly you need to get it together and the budget you have.

I would use Sketchup too !
Easy to use and uses the tex you got.....
But its not automatic !
Rich and I have posted a lot on how to use it with Truespace..

Rayman is better versed in Sketchup than I , I am still learning my way thru the program...
Another option to consider is PhotoshopCS3/CS4Extended and the Vanishing Point filter and than using After Effects CS4 to create the video/movie.
VideoCopilot, do a search on them and you will find a bunch of tutorials, one he does takes it from space (orbiting earth to the ground level. Even if you do not use thissoftware it would be a worth while vide to watch because it shows the basics of this type of shot. The workflow is fairly standard from app to app in how you tackle something like this.
So you have lots of alternatives depending on the software you have and want to use.

Rich I´learning too all the time but I use it every day so that sums up a little.
Note that with all the photomatch software to work you will need to have
pictures from different angles and with Sketchup you dont you just need
the outlines from the top and you can use ordinary pictures from the ground
to do the rest.
With Photomatch you are going to fly around pretty much !
Also beware that there is very expensive software that can do it
with special data and can be automated but thats only good if you have lots of budget !:D

Hey Pete, I agree on the textures, any of the above listed programs are capable of extracting elements from the photo for just texture purposes, without that you are really limited.
ImageModeler2009 has the ability to work from panoramas (full 360 degree panos, they do not need to be 360x180, but they have to be 360), that is an amazing plus for this type of full site modeling.
Essential tools for archviz camera matching are (IMHO)
Sketchup
Vtour (RealViz, swallowed up by the technology eating giant AutoDesk)
PSCS3E and above (Adobe)
After Effects CS4 (Adobe)
Image Modeler 2009 (AutoDesk)
a good 3D application that exchanges data with these programs is important also
Do not discount TS though, I have been experimenting with this on the WS side, while it is not an easy task in many cases, TS can do far more than one would think. It all depends on the budget and the software you prefer.

Nope TS can do a lot but is still lacking some of the tools that would make it easy to trace in WS side.......
Talking about the highend way of doing it ... there was a good article about that on "The day after tommorow"(New york scenes) that was 2,5 d and they used special data and software to make that but I cant find the article.....
as far as I can remember it takes special data that already exists in
libraries from geo data but cant find it .... maybe searching around the web on that would help....
Heres one way of doing it that I found....

:D I did not say it would be easy :)
You would be surprised though what you can do in TS WS side. I use PSCS3E to extract textures all of the time, bring them into TS WS side and model from them, I have many examples around here, modeling an overhead shot would be the same basic technique you would use in Sketchup... Modeling in the detail would still work in TS though admittedly the toolset in Sketchup is perfect for this kind of work... Sketchup also does camera mapping, TS is just not even clse in that reguard... it all depends on the budget, time, and the amount of detail you need...
Sorry, I was trying to upload a scene I modeled from a pano in VTour, it was a proof of concept for the client. No big deal, I am waiting for the hi resolution panos to do the complete temple from the inside... For lsome reason these forums do not like zip files, I have a hard time uploading them all of the time...

Yep photoshop with vanishing point and google sketchup would be my two choices for quick and easy. |

I have downloaded and tried the demo of Photomodeler and it seems that this program is the best tool for that job (the indstrial site is too large and complex to model by hand, so the other programs/workflows won't go).
Now, I have to inform my client of the cost of that tool :p
A huge THANK YOU to all the kind people who responded. That was really helpful !
:banana:
That topic also demonstrates a general interest for this kind of tool. Let's hope Microsoft will have the good idea to implement its Photosynth code into trueSpace soon :) |

One of the reason forum exist is so we can get good user feedback like this. I wonder if more people would like this type of tool, feel free to post on this or other unrelated suggestions, we do read forum posts even though we do not always respond right away. |

I think you found at least 6 people here. I know a graphic guild of 1500 digital media artists that would be very interested in a tool like this.

Speaking of Ts not making any advances when its a map making tool
like google.Earth...
Quite frankly thats some of what I want to see in a future release !
If it makes it easier to build my enviroments (like with image modeling or
simple drawing...)!;)
Count me in on this one ...
very interested !

This was all done on the workspace side of TS. I traced the buildings from the arial photo using the Add Polygons tool then extruded the traced faces using Dynamic Sweep. If you want the buildings separated from the arial photo, just delete the arial photo plane when you're done with your extrusion.
I did have to create a UVmap for applying the texture. |

Very nice Heidi. Would be cool to see some horses and or what have you. Bringing some life to it all. Well done! :) |

Thanks TrueBlue. The final version of this does have horses included, but I don't want to usurp this thread. :) |

You had to ask Roman? Of course we would love to have a photo modeling tool in truespace in the future! One of those kind that you just take the pictures, and it makes the 3d models would be great, but even a photo trace type tool like what the new version of sketchup has would be great too.
I have tried several times to get Caligari people to be more interested in photo modeling tools by making posts that gave links to photo modeling programs, and plugins.
There is a good plugin for photoshop, that will automatically make models from photos, so one option for you Roman, is to contact Adobe software, and see if you can get a sdk and or developers info from them on how to add plugins, and then add an adobe plugin interface to Truespace.
Then we could buy this plugin for about $300 and use it in truespace.
Do a forum search on photo modeling, and you will find info on this plugin, and where to get it. |
