Abstract: The disclosure relates to a method and system for storing, sharing, rendering, and simulation of 3-dimensional digital data models so that the model cannot be copied or distributed or physically replicated and thus maintain the security of the model. Protecting a file containing digital data of a 3-dimensional representation of an object suitable for reproduction by a 3-dimensional model-making device. A method comprises converting a digital data file representative of a 3-dimensional object by removing predetermined parts of the digital data file to create a converted digital data file and encrypting the converted digital data file using an encryption algorithm and encoding key to create an encrypted digital data file having a file format; and making available the converted and encrypted digital data file in the file format to a software environment, wherein the software environment is suitable for decrypting and reconstructing the digital data into digital data.

Abstract: A method for creating an animated image of the bones of a body part is described. The steps include converting Computed Axial Tomography (CAT or CT) scan and Magnetic Resonance Imaging (MRI) 2-dimensional cross-sectional images (slices) into 3-dimensional images of individual bones (FIG. 1). A first ordered series of slices of a body part in a first position is converted into a 3-dimensional representation of the skeleton of the body part and then a second ordered series of slices of the same body part in a different position is converted. The converted images are then used to create a step frame animation of the movement of the skeleton of the body part. Additional ordered series of slices of the body part in other intermediate positions could be used in the step frame animation. The steps of the method may also include the process of separating the bones if they are depicted as co-joined in a slice (FIGS. 6 and 7). The method can also include the identification of isometric points (FIGS.
