I just want to know what do you want to develop? For example: (1) Create a digital object from 2D planar images; or (2) Digitalize a object from the medical volumetric images.
If your target is the first: keep in mind, each 2D image loses the depth information, you have to use those image to reconstruct the depth information from matrix (Fundamental Matrix) computation (Epipolar geometry) in the computer vision. https://en.wikipedia.org/wiki/Fundamental_matrix_(computer_vision)
if you target is the second, you can acquire the data from one of 3D imaging scan of different modalities(MRI, X-ray CT, Confocal, OCT, CryoEM, etc.). Those 3D scans can create object's information using the greyscale slice. The isosurface presents the 3D surface of object. You can find the reference from the Figure 9 in the following paper:
