I had a customer log a case recently with quite an odd problem – and an even more odd fix. When you import an image and surface from Google Earth, the image is draped over the surface as a render style when you view the surface in 3D. However, a particularly annoying thing can happen – the image becomes flipped for some odd reason. Follow the jump to see what I’m talking about and how to fix it!
In the image below, you can see the Autodesk Manchester office (home of your Product Support team!) I used this site because it is familiar to me and also has a very distinctive feature – the river running right through the middle of the image next to the office – trust me, this will make things much more obvious later on in this post. Pay special attention to the navigation cube and which way North is pointing (straight up the image.)
Now, to see exactly what the problem is, let’s throw this surface up into a 3D orbit with the object viewer.
Once again, take note of which way North is – again, straight up the image. However, something doesn’t look exactly right here – notice anything wrong with the river? That bridge that crosses the river on Granite Street should be on the south side of the image, not the north side of the image. And the river doesn’t curve to the right at the top – this image is flipped!
So how do we fix this image? I’m going to warn you – it’s not what you’re thinking. Type 3DCONFIG at the command line. On the next window, select Manual Tune. In the Manual Performance Tuning dialog, deselect Enable hardware acceleration. Now select OK twice to get out of the dialogs and go back into the object viewer.
Once that is set, you can go back into Object Viewer to see that the fix worked:
Happy Image Draping!
