Data of skull

Hi, We are trying to develop a image reconstruction simulation for the skull. The problem we are having is that we cannot obtain 3D data for the skull. We can just video a rotating skull, but that will only give us 2 dimensions.

Anyone out there got any suggestions?

Please help

Thanx

Yup, you can get a skull contained in the {*filter*}ware_demo from the
following location:

In order to get the {*filter*}ware_demo via ftp do the following:

1) ftp taurus.cs.nps.navy.mil
2) login as anonymous, guest as the password
3) cd pub/dabro
4) binary
5) get {*filter*}ware_demo.tar.Z

Once you get the demo onto your workstation:

1) uncompress {*filter*}ware_demo.tar.Z
2) tar xvof {*filter*}ware_demo.tar

The skull data is called 'phred' and resides in the data directory.

You could paint the skull mat white, then do some complicated
shading analysis on it.

You could do high resolution CT (computed tomographic) scanning of
the skull. Many CT scanners have an algorithm to do 3-D
reconstructions in any plane you want. If you did reconstructions
every 2 degrees or so in all planes, you could use the resultant
images to create user-controlled animation.

Well I've had a look at the data for the {*filter*}ware demo, and the
data/phred file is there (allegedly the 3d-data fro a skull), but
what is the format ??

Kingsley,

the format is a {*filter*}ware format, but if you look in the
{*filter*}ware_demo/convert directory you will find executables/source code
to convert a {*filter*}ware data file to various other formats, eg. ASCII,
wavefront, alias, etc., also, there is a program in the same directory
called 'cyges' which will convert a {*filter*}ware data file to IGES. The
color files are in SGI imagelib format, so that any of the tools in
the ~4Dgifts/imgtools directory on an IRIS will operate on the color
file.
