It has a 360-degree sliced image of a lamp image placed on a tabletop. ( .tiff, Color IMAGE )

I want to concatenate these images into a 3d image. I confirmed that volumeViewer exists.

Can i make a 3d image out of this? Or is there another way?

The image has images in sequence from 1-360 degrees. ( 0degree.tiff, 1degree.tiff ~~ 360degree.tiff )

Even simple code is fine. Please share information.

There are only left and right images. Vertical rotation is not taken into account.

for k = 1 : 360
    fileName = sprintf('%ddegree.tiff', k)
    sliceImage = imread(fileName);
    if k == 1
        [rows, columns, numColors] = size(sliceImage)
        % Allocate the whole array (for speed).
        image3d = zeros(rows, columns, 360, class(sliceImage));
    end
    image3d(:, :, k) = sliceImage; % Put this slice into plane k of the 3-D image.
end

thanks for the answer.

If that code is done to convert to 3d image, how to view it in 3d form?

Try the volViewer app.

help volumeViewer
 volumeViewer View volumetric image.
    volumeViewer opens a volume visualization app. The app can be
    used to view 2-D slices of a volume and do volume rendering, maximum
    intensity projection, and isosurface visualizations of volume data.
 
    volumeViewer(V) loads the volume V into a volume visualization
    app.
 
    volumeViewer(V, L) loads the volume V and labeled volume L into a volume
    visualization app.
 
    volumeViewer(____, Name, Value) loads the app using the Name/Value pairs
 
    volumeViewer CLOSE closes all open volume viewer apps.
 
    Parameters include:
 
    'VolumeType'        String or character array defining the type of
                        volume being loaded, specified as one of the
                        following values:
 
                        'Volume' - intensity volume
                        'Labels' - labeled volume
 
                        When the volume is categorical, default VolumeType
                        is 'Labels', otherwise the default VolumeType is
                        'Volume'. This NV pair is ignored when the second
                        syntax of two volume is used.
 
    'ScaleFactors'      Scale factors used to rescale volume(s), specified
                        as a [1x3] positive numeric array. The values in
                        the array correspond to the scale factor applied
                        in the x, y, and z direction. Default value is
                        [1 1 1]. This NV pair is ignored when 'VolumeType'
                        is 'Labels'
 
 
    Class Support
    -------------
    Volume V is a scalar valued MxNxP image of class logical, uint8,
    uint16, uint32, int8, int16, int32, single, or double.
 
    Labeled Volume L is a scalar valued MxNxP image of class categorical,
    uint8, uint16, uint32, int8, int16, int32, single, or double.
