Re: [Flightgear-devel] Ground structures pulled from diagrams.
Yes svg2ac can be a real improvement in speed, the whole process takes seconds(except for the altitude fetching part, but that can be improved~minutes). The errors currently can not be corrected in Blender, the first one is a bug in my code, the second is inherent to FG(but there are techniques to fix that). Basically what we need is pdfs of buildings layouts, that we can convert to svg and then to ac using svg2ac. So far we have been able to find only airports, but we haven't really looked around for detailed city maps.

Without that, I dunno. snip So the question is, how easy/hard will it be to edit the structures after generation -- to give them a look other than grey/white boxes? Sure, just open the resulting AC3D file in your favorite 3D modelling tool and apply a material. People can also modify the the svg2ac source code to have this done automatically. In response to something I was playing with a year or two ago, David Megginson made the point to me (and I had to concede he was right) that scenery objects that look crude (in a graphics sense) can be worse than if they weren't even there in the scene at all; they stick out against the more realistic-looking terrain, runways, etc., and break the user's suspension of disbelief. Of course white boxes would stand out. Once a material has been applied however, the resulting grey boxes should blend in fairly well with FlightGear's scenery at this point in time. Are they going into invididual .ac files, or one big .ac file for an entire area (including many buildings)? Or is the plan to provide some generic wall/roof colors or textures to these structures when generated? They are one big AC3D file.

Automatic creation, sizing and placing of objects is great, and applying a generic texture should not be too hard. At least it eases the job for locals to adjust their airport to exact matching with reality (And non locals will find it easier to find the airport by surrounding buildings rather than a bare runway somewhere). Greetings, Yep, that's the whole point of the automatic airport generation process. The goal is not to automatically generate a finished product, but to generate templates and let those who are interested to do the enhancement.
