Hi,

I am currently trying to combine four 2D images at angles 0,45,90 and 135 degrees into one 3D image.

At angle 0, I have image 'I1', inside 'I1', I have 6 variables(in array) to determine the contours of the image. This is the same for the other 3 images, 'I2','I3','I4', each having 6 variables of the same name as 'I1'.

I have use:

A = cat(3,myData.I1,myData.I2,myData.I3,myData.I4);

to combine all the images. I cannot see what is inside 'A'. When I double clicked on 'A', it shows me:

val = 
1x1x4 struct array with fields:
    newEp
    newEe
    newlEi
    newrEi
    newlEl
    newrEl

How can I make sure that what I'm doing is correct?

It sounds like you are looking for one of the image reconstruction algorithms (i.e. from tomography):

It's hard to say if this is actually what you want though without knowing what your images represent.

My images actually represent the human eye. Each image's variables are the contours(coordinates) of the human eye at one angle. I have to combine these four 2D images into one single 3D image.
