How Virtual Woodscape was created

If you take the flat surface of a plywood sheet and make a digital photograph of it, you can extract the visible lines to produce a contour curve map. These lines may be assigned different levels in a 3D computer program. The relations will then show up as a digital terrain model (DTM) on the screen. It is possible even with a simple computer programme to make spatial representations, but there are many different ways of doing it. I decided to stick to the barebone facts of the pattern and to apply as much of the surface quality information as possible to back up the realism.

The logic is simple. All years are equally long, but growth will vary as we all know. The timeline of growth is represented by the height axis. The amount of growth is represented on the two horizontal axes in the virtual 3D space. The parts of the tree in its young age are on the top, because there is less of that. The wide areas below are newer, which means from a time when the tree was older.

For steepness, I decided that the (constant) vertical distance between levels should equal the horizontal distance between lines when density of contour lines is average. Such a slope will be 45 degrees, which corresponds neatly with a normal geological sediment slope angle. I found this to be the most truthful way of determining the steepness of the landscape and it looks natural all over.

I got help at the university in Trondheim to make very large high resolution photographs of the wood material. The combined photo is around 1000 times larger than a normal digital photo. Only recently I joined all the parts into one picture, as available programs and document formats still pose some limits. So as the project evolves, I'm sure there will be surprises and many discoveries to be made. -20080629-
