Abstract:
A computer-based 3D modeling system for constructing a virtual 3D representation from a plurality of data images of 2D cross sections having a mutual spatial relationship comprisinga data source module through which can be extracted the plurality of data images of 2D cross sections having orientation and positioning information for each of the plurality of data images according to the mutual spatial relationship; a frame creation module capable of creating a planar frame for each of the plurality of data images from the data source module; a texture-mapping module capable of mapping each of the plurality of data images from the data source module onto its corresponding planar frame from the frame creation module as a texture; a rotation transform module capable of using the orientation information for rotating each planar frame from the texture-mapping module about one or more axes in virtual 3D space according to the orientation information; a translation transform module capable of using the positioning information for translating each planar frame from the texture-mapping module in virtual 3D space according to the positioning information.
