Are there possibilities to do an automatic texturing with oblique aerial photos in fme? Ther eare some software like CityGrid or RhinoCity who can do that. They only need some parameter regarding orientation of cameras. We have an production workflow for CityGML buildings in fme and we would like to texturize within the workspace or by implementing existing functions or something else. Does anyone know if this is possible by using FME?

Hi @limo​,

FME gives you enough control over the UV texture coordinates of the oblique images that you could use them for texturing, but FME does not currently have any prebuilt tools to calculate those coordinates from image location, orientation and focal length, nor can it calculate the occlusion from surrounding buildings.

Hi @daveatsafe​ ,

thanks for your answer. ok and are there developments for this in the future?

For example with roof polygons it is more or less possible to add roof textures to buildings:

Input:

  • TrueOrthophoto -> Raster Resampler
  • Roof Surface -> 2DForcer -> BoundingBoxReplacer

Process

  • Clipper -> Attribute Keeper -> Raster Mosaiker -> Appearance Styler-> Appearance Setter

 

But for Wall it is based on TrueOrthophots not possible. Here we are limitated to oblique images.

It will be awesome if ther ewill be the possibility to do this in fme!

So at the moment we cannot do this in fme. Only with external tools/software.
