I am trying to create a seamless 3D visualisation in ArcScene 10.1. I have a TIN surface created from 1m contour lines. I have 4 tiles of ortho imagery I would like to drape over the surface. So far I have been using the Base Heights tab in the properties dialog box on the images to "float on a custom surface" so that the imagery takes on the 3D shape of the TIN surface.
However, the result is that most of the image looks great draped over the surface except where the images come together, I get a very jagged seam, as if data is missing. Here is a screenshot:
I have tried increasing the layer offset to see if I could raise the images above any noise or elevation irregularities but it doesn't make a difference, I still get the seam gaps.
When displayed flat (not floating on custom surface) the images fit together perfectly with no gaps.
How can I display this imagery in 3D using ArcScene or other software so that it appears seamless and without gaps?
