How would you convert a three-dimensional (3D) image to a two-dimensional (2D) plane?
Describe at least two different strategies along with their advantages/disadvatages and properties.

Please don't post your question four times!!!

..and we won't do your homework for you.

Sorry. Double post.

That sounds like a homework question to me..... are we doign your school work?

Snap a digital picture of your screen.

I am working as 3D simulator for 3 years and I am using various CAD software. I don't understand your question about 3D image to be projected in 2D plane.

But if you mean as image(jpg,gif,tif,bmp etc.) with 3D effects ( it looks like 3D) then that image is still 2D. It is flat just like any pictures taken by a camera or any perspective rendering by artists or architects.

I never found any software that you can project it to 2D views, such as front view, side view, top view and auxiliary view.

However, if you are working with 3D Objects which are created in any 3D software such as, AutoCAD, Mechanical Desktop, Unigraphics, Solid Edge, etc.
Then it is easy to generate any 2D views you want.

I'm only aware of one type of true 3D imagery - holograms. If it's in a digital image or printed format then it's just a 2D representation of a 3D object/model. So, are you looking to convert a holographic image to a digital image?

I suspect what you're talking about is having 3d data, e.g. (x,y,z) points, that needs to be transformed to (x,y)? The answer is matrix algebra. You need to define a point in space that's the viewpoint of the observer and normalize the data to that point. Actually, you need to define a view plane. I seem to recall this involves some 4x4 matrixes.

Hope this helps.

Anyway, regarding the op, I would suggest a bulldozer.

i think that it depends first on the software that u r using.
for example: in 3D MAX, u an convert it from texturing ... in photoshop u can use differnet filters to convert 3d into 2d..
the advantages and disadvantages depend on why u r changing them and for what???simply... specifiy ur objective in ur question
