Is it possible to construct 3D images using GRASS from jpeg sources?
CT scans and MRI scans are examples. The images are lossless grayscale jpeg
format. (There is a standard called DICOM which would probably be the target
of any serious work) Each image represents a "slice" with a known position,
resolution and orientation. A number of slices are spaced at a known
incremental spacing in the third dimension. It looks like a perfectly good 3D
data source to me!
In simple terms, all that needs to be done to get started is to stack the
slices into a 3D raster map, so as to be able to render them using NVIZ, for
example, or for any other uses that anyone might devise for any other
existing GRASS functionality.
Is anyone playing with this type of application?
you won't find many functionality for the reconstruction of 3D elements
from your images in grass. perhaps you should have a look at
