I've got terrain data in GeoTIFF, a DEM in ArcView Grid, and some vector points and building footprints in Arc shape files. I'm successfully using ArcScene to build and export a VRML. The building footprints are extruded by ArcScene into 3D buildings.
I've written a C# program using Acrobat 3D 8.1 SDK to convert the VRML into PDF and am able to open and view, but my buildings are all jumbled up. They seem to turn into pyramids. The more irregular the building footprint, the more bizarre the PDF buildings.
If I open the VRML in Deep Exploration 5, then export as U3D, my C# program converts the U3D correctly into PDF, but I don't see an automated method to do this. The file size is also about 25% smaller when I do this, so that is nice too.
If I open the VRML in Acrobat 3D toolkit, the buildings look good but the terrain is missing. The terrain seems to be what the toolkit refers to as an external texture, but it does not appear in the information bar and I cannot figure out how to turn on. If I export to U3D from toolkit, the terrain is still missing, and the buildings take on a different pyramid distortion.
I need an automated process to get this data into PDF, but for every solution I find, another problem arises.
Any suggestions or practical experience would be appreciated.
