Geometry extraction

[Karlos]

Hi all,

Does anybody know if there is any geometry extraction software for AmigaOS?

I don't know what the correct terminology is (photogrammetry or something like that), but it works by analysing several photographs of a scene taken from different angles and calculating a 3D mesh that corresponds to the original scene by locating and correlating edges in the original set of images.

A bit of a long shot but I thought it could be an interesting way of building 3D game engine maps of real places (with a bit of polygon reduction, obviousy!)

Thats kind of what I figured. I know a fair bit of 3D projection mathematics, it should be possible to back project from a pair of 2D images to calculate depth.
After all this is what goes on in your noggin whenever you look at something with both eyes open...
