An image processing device is described herein including an information input unit that receives as an input three-dimensional structure information indicating a three-dimensional structure of a heart; and an image generation unit that develops an inner wall of atria and ventricles of a heart indicated by the three-dimensional structure information into a two-dimensional image based on an equal-area projection, and generates a developed image interrupted by dividing the two-dimensional image into a front wall, a rear wall, a left wall, and a right wall.

A method for visualizing a tubular object from a set of volumetric data may include the steps of: determining a viewing direction for the tubular object; selecting a constraint subset of the tubular object within the volumetric data; defining a cut-surface through the volumetric data and including the constraint subset of the tubular object within the volumetric data; and rendering an image based upon the determined viewing direction and the volumetric data of the tubular object along the intersection of the volumetric data and the defined cut-surface. Additionally or alternatively, the method may identify a plurality of bifurcations in the tubular object; assign a weighting factor to each identified bifurcation; determine a bifurcation normal vector associated with each bifurcation; determine a weighted average of the bifurcation normal vectors; and render an image of the volumetric data from a perspective parallel to the weighted average of the bifurcation normal vectors.

Other examples are described and claimed.

A two-dimensional drawing of a three-dimensional wire harness model is generated by selecting a starting node from a plurality of nodes of the three-dimensional wire harness model, where the starting node is directly connected to a first bundle and a second bundle of the plurality of bundles, wherein further each of the first and second bundles are representable by corresponding first and second vectors. A reference plane is defined based on an orientation of the starting node, the first vector and the second vector, such that a first adjacent node may then be mapped onto the reference plane by geometric translation. Thereafter, a plurality of mapping operations are sequentially carried out until each of the plurality of nodes and the plurality of bundles have been mapped, by geometric translation, to the reference plane, and wherein corresponding translation matrices are stored in association with corresponding ones of the plurality of mapped nodes and/or the plurality of mapped bundles. The two-dimensional drawing of the three-dimensional wire harness model may then be generated such that the two-dimensional drawing includes three-dimensional orientation data corresponding to the plurality of bundles.
