I don't know how to "reply" to a message on the web interface... Can somebody
give me a clue? :)
David C. asked, "How does the use select an area from the photo? Do they set
points that connect into a solid polygon (trivial)"
Yes. I imagine them either "painting" the area (creating a solid mask), drawing
around it, whatever. There might could be a "wand" that can try and determine
what the area is, but that's more complicated than I want to get.
David C. asked, "How much 3D information is supposed to be gleaned from the
image?"
I propose the designer sets three "markers" (in a triangle pattern, or one
triangular marker with three points) in the area and measures the distance from
the camera to each, as well as the height off the floor of the camera. Using that
data, the slope of the area can be determined. The computer would then be able to
simply apply a texture to a square, form the square to be parallel to the plane,
and use the mask to apply the 3D tile on the surface. With Win32DIB, this sounds
very easily doable.
Right? :)
