Hello I have a set of Disc Image Files. I would like to know how can I reconstruct 3D model from these images.
Thanks in advance.

You will have to be more specific than that.
Is there something you want to mention about the significance of them being on a CD (or an image of a CD) rather than on a harddrive? Is this about the image format itself or the format of the 3D models inside it?
In what format are the files?

yeah, i guess the 3dmodel files are on a disc. Totally a mix of composition.
Image of a CD is called so, but its a ditto copy of the cd content, but in a file. If thats what your looking for Jenny_wui, then you gotta
a) burn it to a disc or
b) mount it on a virtual CD drive.

The file type is written as Disk Image File. I have 90 X-sections i.e. 90 Disk mage Files. All I am concerned about constructing 3D model from the images. I would prefer surface-based rendering. I have never dealt with these kind of images. Please provide me with some suggestions.
Thanks again in advance.

I received a folder containing a set of cross-sectional images of coronary artery acquired by IVUS pull-back. It is said that each image is stored as raw format where the size is 256 pix by 256 pix with 1 byte per pixel (i.e., 65536 bytes per image).

Hi, I have been able to open the file. Now I want 3D surface-based rendering i.e. the model should be polygonized. As it is difficult for me to write some algorithm like marching cube , could somebody provide me some further suggestions? Thanks.

First hit on google for "marching cubes source code"
Another alternative (at least for quick visualisation, doesn't make 3d geometry) is to render a point cloud i.e. camera facing sprites/billboards which should be easy to get you going.
EDIT: I'd go point cloud first, then just cubic voxels, then marching cubes dem voxel asses.

I really like your approach. I have also some theoretical knowledge on volume-based and surface-based rendering. I shall be able to develop the point clouds and later the voxelized model myself. But from there while constructing iso-surface using marching cube algorithm seems a bit difficult to me as the algorithm has too many options for each voxel. I need some tutorial help which shows both volume-based (ray tracing) and surface based reconstruction (marching cube) for the same simple model from which I shall be able to understand how to work for my model. If there any related website, please let me know.
Thanks every body for the suggestion.
