Push the Full Extent button. A lot of visual information will appear, although it is mostly covered up by the TIN. You are viewing it from a point southwest of the image and well above it. This is what is considered full extent in ArcScene. We will explore these data sets using the Navigate tool in ArcScene. The Navigate tool is a bit like a Swiss Army knife—lots of different tools in one artifact. As such, it is both useful and dangerous.
