      Easier might be the wrong word, maybe more cerebral. To do natural language interpretation, I would envision you start with a "dictionary database" full of objects. These objects would be nouns, and then you could program in properties on them known as adjectives. Without a "dictionary database" of known objects, I could not figure out how to code natural language. So you're right that natural language is more difficult than digitizing things because digitized things are a component of natural language. I just think if I have a database of digitized objects that writing a natural language on these things might be easier than the digitization in itself, but not noticeably easier.

      So you start with nouns "dictionary objects", then you add adjectives by changing nouns properties. This is hugely time consuming, and the exercise is mostly done to figure out a best practice while you're doing it. But say you add all adjectives to some nouns. You then create an imagination space, and describe the nouns in action verbs Then you describe the verbs more adverbs. It is a huuuuuge undertaking, but the cool part is that you can work on subsets of the language with a small environment. Just start with a small room with a ball in it, and keep adding more nouns, adjectives, verbs and adverbs.

      Interesting. I never heard of SHRDLU before, but I have heard of Cyc wikipedia said came after. From what I've heard of CYC, CYC only takes words in relation to each other, but does not have a physics space in which to have "imagination space". Because of this, CYC doesn't sound like it should ever achieve AI.

      However SHRDLU does sound promising. I would think if they enhanced the physics and vocabulary on SHRDLU, it could become "imagination space" for future AI. I knew this part could be created independently of "vision recognition" part, but I've felt that it'd be better if the vision recognition was done first. After all, if you're databasing objects on their real world dimensions, they'd work better in the physics imagination space because you have the exact dimensions and contours of the object. I mean, if you're gonna sit there and database in many different objects based on their geometry, might as well have it done automatically. Of course I wasn't thinking to start small with basic objects in a solid physics engine.

      Interestingly enough: I think this is an area which advances could be made now. I wouldn't exactly start with SHRDLU because it is early 1970s technology. I'd shop around for good physics engines first. I have no money to buy physics engines, so I'd personally have to go with the best free one... So maybe I'm incapable of doing this research due to lack of funding. Anyway, someone else can do it: Find a good physics engine, then start databasing "Nouns" "Adjectives" "Verbs" and "Adverbs" maybe looking at initial SHRDLU code just for advice. The thing that makes me interested now is that I realize that many objects are not exactly the same objects: Trees are trees, but even the same variety of tree has different growth stages and limb orientations. So for generalization terms, it could be good to look at things like "Spheres" "Cubes" "Pyramids" and so on.

      Thank you for putting me onto this. I think it is something that could be solved now with enough time and energy. The reason I put it off was because I made the assumption that the 3d digitizer could double as an "Object databaser" for inputting objects into the database.

    - better civil engineering planning (seeing how a project will affect its surroundings)
    - archaelogy (understanding old battlefields)
    - current military (understanding new battlefields)
    - terrorism (see "current military")
    - tourism (find hotels/other with good location)

      3D Aerial photography is already a big, well understood field. The only novel thing here is the fact that they made a cheap version of it, that's accessible to low-budgets.

  19. Not ready for prime time by fragMasterFlash · · Score: 1

    The OBJ format sample model on the Pix4D site doesn't play nice with nice with Alias. Having to tweak either the OBJ data or the viewer to get a firsthand view of the model tells me this service is not quite ready for prime time, and likely in need of significant funding to get to production quality.

    If you live in the US just go to government servers and download high quality 3d terrain models in several different formats. Used them frequently in engineering. We did have to resort to flying our own photogrammetry when tolerances were tight, but that was rare.
