To drape polygons over terrain is extremely difficult task, no wonder sometimes ArcScene fails to do so. You can help it by splitting complex polygons into basic triangles. This Cutting rectangle set (not squares) into triangles using ArcGIS for Desktop? will give you idea on automation of the process

I'm not sure if this helps, but I used ogr2ogr and converted from shp to shp adding the -zfield argument and was able to reference the shp into microstation as contours with elevations. ogr2ogr -f "ESRI Shapefile" {outFile.shp} {inFile.shp} -zfield {ColumnWithZValue}

There is a very straightforward way to load GIS data directly into Blender with this plugin by Domlysz. The wiki shows how to install and use it. I've had the best success using projected datasets rather than lat/lon, only as I find it easier to match metres to Blender units when manipulating the data in 3D. Blender should also ignore the separate channels ...

Clip the image to the size of the DEM then export the terrain only to Blender then apply the clipped image as a texture in Blender?

I started to dive into VTK - The Visualization ToolKit (VTK) is an open source, freely available software system for 3D computer graphics. It is pretty powerful and robust tool, seems to be able to do all the operations I asked for though I can't confirm it all yet. On the other hand it doesn't support datum and projection as is expected from GIS software. ...

Akio, Unfortunately what you are trying to do is very difficult. I have struggled with this a lot myself, and from what I have found in my search for a similar answer often times led to people suggesting using models with SketchUp or some other modeling software. I did however find one useful page that helped me wrap my mind around some ways around this ...

You can, but... you need to think about things differently. When you import GIS data into Blender, it will lose the attribute data especially if you use any of the available plugins. To import your data into Blender with attributes you will have to write your own script (as I don't know of one which does not simple import geometry). The script will need ...

The error message you see is the generic exception text that is thrown when the CesiumTerrainProvider cannot build the mesh for the requested terrain tile. This message can indicate that the terrain tile was not retrieved from the tile server, but could also mean that it could not make sense of the data it received. In your case, passing a blank terrain ...

pgr_fromatob() from http://workshop.pgrouting.org/chapters/wrapper.html is unsuitable for 3D routing since it only covers finding the nearest network node in 2D. You need to adapt the code to find the nearest network node in 3D. Afterwards, everything else should work as in the 2D case. Something like (untested!) -- Find nearest node EXECUTE 'SELECT ...

The Profile Graph tool in ArcGIS does not work if the input DEM and the selected line feature are not in the same coordinate system. To test this statement, I used a DEM in UTM coordinates and a line feature class in US State Plane. My result was a graph with a constant elevation of one. I reprojected the line feature class to the UTM coordinate system and ...
