A 2D image is constructed from constituent 2D images that show different views of the same object. Construction is performed by taking image tiles, referred to as tonal triangles, from the constituent 2D images and combining them using 3D data for the object. The 3D data define a wireframe model comprising triangles, called contour triangles. Two tonal triangles are combined based on neighbor relationships between the contour triangles that correspond to those two tonal triangles. Additional tonal triangles may be combined as desired, until the 2D constructed image is of a size that shows the subject of interest. Compared to conventional processes for stitching and montaging, the process generates a 2D constructed image that is a more accurate presentation of the true area, shape, and/or size of the subject.

Methods for creation and use (e.g., for navigation) of displays of flattened (e.g., curvature-straightened) 3-D reconstructions of tissue surfaces, optionally including reconstructions of the interior surfaces of hollow organs. In some embodiments, data comprising a 3-D representation of a tissue surface (for example an interior heart chamber surface) are subject to a geometrical transformation allowing the tissue surface to be presented substantially within a single view of a flattened reconstruction. In some embodiments, a catheter probe in use near the tissue surface is shown in positions that correspond to positions in 3-D space sufficiently to permit navigation; e.g., the probe is shown in flattened reconstruction views nearby view regions corresponding to regions it actually approaches. In some embodiments, automatic and/or easily triggered manual view switching between flattened reconstruction and source reconstruction views is implemented.

A method is provided for generating a three-dimensional morphable model of an element from an initial database of examples of such elements providing data allowing, for each of the elements of the initial database, a three-dimensional meshed surface based on points and on a triangular network connecting the points to be determined.

A system determines an object-design for a three-dimensional model of an object. The object-design may exhibit a design continuity. The system breaks the object-design in to spatial patterns corresponding to the discrete surfaces making up the outward surface of the object. The system then generates flattened patterns by projecting the spatial patterns into a two-dimensional plane. The system prints the flattened patterns on to designated regions of material sheets in an orientation that preserves the design continuity of the object-design. The regions may be extracted from the sheets and then joined at their edges to form a cover for object that exhibits the continuity of the object design.

This application discloses a design system implementing tools and mechanisms to receive three-dimensional design data corresponding to a wire harness from a mechanical design tool. The tools and mechanisms can identify the three-dimensional design data includes a geometric description of one or more rigid or inflexible components in the wire harness, and convert or flatten the three-dimensional design data into a two-dimensional representation of the wire harness, such as a two-dimensional layout of the wire harness, which conforms with the geometric description of the one or more rigid or inflexible components in the wire harness.
