Where does a novice user find 3d images?

I am a complete novice, just opened an account today. Came here searching for an ability to download 3D images as suggested in this video but which in practice I cannot duplicate:

Anyone know how I can achieve his results? I well may be in entirely the wrong place, I know. Sorry, if so. :)

If you are referring to the DEMs included with the ALOS PALSAR RTC products from ASF, it is important to note that they are NOT generated from ALOS PALSAR imagery. They are the DEMs that were used for RTC processing, which were simply mosaicked and clipped from publicly-available DEMs, such as SRTM and NED. They have been resampled to match the pixel spacing of the RTC product (12.5 m for the high-res product), but that is NOT an indication of the original DEM resolution.

Refer to https://asf.alaska.edu/information/palsar-rtc-dem-information/ for more information about the DEMs included with the ALOS PALSAR RTC products.
