Its a little hard to work with the small thubnails but the bottom two phots pretty clearly have misplaced vertical vanishing point. The top right is a big tricker to tell, with the camera plane seemingly in line with the top of the box, very small movement in the left or right vanishing point will swing the magenta line form vertical vanishing left or right. In three of the photos I've added new yellow vanishing point triangle, and new magenta lines perpendicular to the horizons. I've added while ring where the magenta lines cross.

efeme75 I have not done anything this this in a while, although there are more photogrammetry and LIDAR based options out now that may be more automated that PhotoMatch. With the approach from this thread, the orientation of the photo relative to the horizon doesn't matter, but it does require an orthogonal object in the scene large enough to find vanishing points, and create perpendicular lines as shown in Alan's example.

Hi David,

I put it up on GitHub.

Thanks!! I'll check it out this weekend.

Jim, what is the licencing like on ruby-dxf-reader? In particular I'm wondering if it could be included in the code base for an open source project http://openstudio.nrel.gov/ or if it could be used in a measure (our equivalent of a plugin) on the Building Component Library https://bcl.nrel.gov/. We already support gbXML as an import option, but I'd like to support DXF as well so almost any modeling tool can be used as a starting point.

I use to do something similar, having many external components, but I did not use an external rendering application. For trees I had simple trees (just a stick) and the real trees. In the master file I setup my scenes and did almost everything with the stick trrees. Then I swapped them for e real trees just before rendering. Using proxies with third party rendering sounds good.

You could take a similar approach to what I did with simple and detailed buildings and simple and detailed terrain. Then have a ruby bath swap them?

Just in case anyone is interested, I posted an update to the OpenStudio energy modeling thread. Our July release had two big milestones. We crossed over to 1.0 from our 0.x release, and we added life cycle cost analysis, so energy conservation measures can be looked at along side capital costs and ongoing utility and O&M costs.

Here is a link to the post in the plugin forum

Another three months, another version of OpenStudio. This is an important one. We lost the 0 at the front and moved to 1.0. The key feature for this version is the ability to add life cycle costs to model and to measures in the Parametric Analysis Tool.

This is one of 4 videos in a playlist for new features of the 1.0 release. It shows how life cycle costs and utility rates are added to a baseline model and then to design alternatives using energy conservation measures.

Let me know if you have any questions. Next step, cloud based simulation and model calibration.

Move the top angle in the board one tread width to the left and it should match the angle of the stair

I had a workshop today, and then I'm the session organizer on a. Session on Friday.

You could always import it as a background watermark and try to manually match a camera view to it. Not sure if the perspective would work for match photo scene.
