stacking of 2d images

Nettai

i am having set of 2d images....and i want to stack those images to visualize 3d image..i didn't get any idea.....i was searching in google,but i couldn't get exact details.....if anyone help me by giving any article or idea related to this......

What?!? what is the 3D image meant to look like? what do the 2D images represent?

Like a volume texture? You may have to ray trace it to get your final (2d) view.. Although there are probably better ways.

i am doing project in computed tomography.....i have 2d images of full hand....i have to stack the 2d images to visualize the full hand

hmmm... i think you may be in the wrong place for this kind of question. How much do you know about 3D graphics. If not alot you will need to start from the basics of 3D graphics. If you can render 3D models(so to speak) then you could create a 3D array of pixels based on your 2D images. I assume your 2D images are RAW files? or something similar, i.e. two colors, 1 color for object, another color for space

How you do it depends on how your images are stored. Is each image in a separate file? Are they bitmaps, jpegs or some other format. I once did something similar where the images (horizontal slices through a head) were stored in a set of files. Each file contained a 2D image as a sequence of integers where an integer corresponded to a pixel. I.e. the file was essentially a 2D array of pixels. To get the 3D image I had to get the corresponding pixels from each file and monkey around with them. In other words I treated the set of files as a 3D array so I could take slices in horizontal or vertical directions. Hope this helps but without knowing exactly how the images are stored I can't be more specific. Regards David R
