A spiral is first defined as a flat figure. Sometimes it is used to describe a three dimensional case.

first of all its not trapiezeim it is trapezium, a trapezium whether 2d or 3d as it is a term it is called trapezium only.
Try looking into Toon Boom, Synfig, and Flash for 2D animation software. Autodesk 3D Studio Max and Maya are well known for 3D animation.
In first-angle projection, the projectors originate as if radiated from a viewer's eyeballs and shoot through the 3D object to project a 2D image onto the plane behind it. The 3D object is projected into 2D "paper" space as if you were looking at a radiograph of the object: the top view is under the front view, the right view is at the left of the front view. First-angle projection is the ISO standard and is primarily used in Europe.
There are a number of applications that require the use of of 2D and 3D scanner. These include CT scans, MRI scans, and simply for printing out 3D models for experiments.
Depends. 3D x-ray could mean CT scan, but there are many scans that are 3D. Around $1000 privately for a plain CT scan.
Barium sulphate is used in hospital scans to show the digestive system. It is very important in CT scans.
3D bone scans are become very popular because of their accuracy in this field.
CAT scans and MRI scans are often used.

The first use of 3D glasses was in 1922 for the movie "Power of Love".
its a machine that scans things... and it's used for scanning
Iodine is commonly used as a contrast dye in CAT scans (computed tomography scans) to help enhance the visibility of blood vessels, organs, and other structures in the body. It is injected into a patient's bloodstream before the scan to improve the clarity of the images produced.
I, Robot was the first game to use 3D polygon graphics. However, the first game to use 3D was 3D Monster Quest which did not use graphics, but rather text.
The first 3D television was demonstrated in the 1920s by John Logie Baird, the inventor of the first television. The quality wasn't good and it was never destined to be anything other than a demonstration of concept. Despite that, Baird successfully used 3D television for the first time. It has taken close to a century for the technology to reach the point where 3D television can be a reality.
