SceneryDesign.org Two users recently reported the same problem to me with autogen files made with scenProc. In Annotator they could not see all the buildings and after saving in Annotator many of the buildings were gone. It turned out this problem was caused by very narrow buildings. So I want to warn all scenProc users of […]
Tree detection – part 4
It’s a while ago that I posted about the progress of my tree detection efforts. So here is a quick update. Some other things kept me busy, so there hasn’t been too much progress recently. I was able to run the tree detection algorithm on the entire island of Nantucket now. It took around 3.5 […]
SPLITGRID? Check!
In my bug reporting system I can see that it relatively often happens that people run into trouble (crashes) because they remove the SPLITGRID step from their configuration file. If you then try to create autogen features scenProc will crash. This is because I assumed that the SPLITGRID step will be done first. This step […]
I flipped it
Yesterday I fixed a bug in the scenProc step that imports AGN files. There was an issue in this step that resulted in part of the autogen features being displayed wrong. They were vertically flipped. So if you are using the import AGN step in your workflow, please update to the latest version and run […]
BGLComp SceneryObject flags
A few days ago I added support to ModelConverterX to read the additional options like <NoShadow /> or <NoAutogenSuppresion /> from the object placement code in the BGL file. Initially I had some trouble to find out where these options ended up in the binary code, since it was not documented in the otherwise excelent […]
Tree detection – part 3
I have made some more progress on the tree detection algorithm in the last days, but I am not there yet. So some more testing is needed before the functionality can be put in scenProc. In my previous post I showed some results from the algorithm running in a test application. What I have done […]
Tree detection – part 2
I am travelling for my work this week, but when I had an few hours in the evening to spend in my hotel room I did some more experimentation with the tree detection algorithm. I have now modified my test tool so that you can click on the trees in the image to determine the […]
Tree detection
One of the first problems I encountered when I tried to make autogen for Nantucket is the lack of vector data for the vegetation. OpenStreetMap contains hardly any vegetation and also the GIS department of Massachusetts has not much usable data. So therefore I started to experiment with detecting the vegetation in the imagery. And […]
Nantucket photo scenery
As I mentioned in my previous post I would write a bit more details about how I created the photo scenery for my Nantucket test project. From the website of the Massachusetts GIS department I could download 30 cm imagery of the entire island. But they came in 101 tiles and in the SID format. […]
Test project Nantucket
I was looking for a way to help me develop the scenProc tool and explore the possibilities of autogen further. In the end I decided to start a little scenery project where I could play around with all aspects of autogen. I decided to pick an area in the US, because there is a lot […]
