Ah I should think so then
If you set it to a reasonable res like 256 or 512 (depends on how much graphics grunt you have) you can press O,P,I,J,K,M for moving the camera and W,A,S,Z,E,R for moving the target position for the camera (the yellow line). So you should be able to get a real time flyable view.
It's intended as a debugging tool for terrains and also as a means to position your party at point A and view point B and show players what you would see.
It can do automated fly throughs but not using the keyboard or without getting it hooked up on the network. For stand alone purposes the network bits on the menu are redundant.
The screen save should work ok too. It merely saves out a fixed filename image.
Edit-- I should also point out that my Jan Challenge had some dragon flight sets to download. I think they are still there for the taking. Put them in a different directory and copy the DF exe to it before running.
