A method was added to my generic map editor, which automatically determines forest type depending on elevation.
After loading this map into a scene program, complete with depth effects, map elements etc, it is easy to see the overall effect of a dynamically created forest based on terrain features. Though in this preview it is still easy to see grid lines of the forest textures. This can be minimalized by randomizing forest values, such as randomizing thin forest values.
Finally, I have an animation system so I can record values for different layers in real time, (such as camera motion, icon opacity etc.) to make refined compositions to show various interactions with the forest system.
