Hawaii DEM Texture Example

In order to demonstrate how FME 2010 works with textures, our core team developer Brittany Zenger created this example.



The attached workspace takes contour data for two hawaiian islands Lanai and Molokai, generates TIN surfaces (TIN_SURFACE is a new TINGenerator output port in FME 2010), and adds portions of a landsat image as textures to each surface (green bookmarks):



The whole image is used as a background for the entire scene (direct link from the JPEG reader to the PDF writer). When we send rasters to PDF3D directly, the writer transforms them into faces with textures.

The output is saved in PDF3D format - see the attached Lanai and Molokai in a 3D PDF.pdf .

World DEM Texture Example

If the workspace above looks a little bit too complex, here is the simplest workspace where the extents of DEM data match the extents of the raster.  A TIN surface is created from the DEM, and the raster is then draped onto the surface using the AppearanceAdder:



The output (~15 Mb)(See attached - WorldDEM.PDF) is also quite impressive:
