摘要： Systems and methods are presented for generating surface lines on mesh surfaces and voxel objects. In exemplary embodiments of the present invention directed to mesh surfaces, such methods include preprocessing a triangle mesh data structure, constructing a grid data structure for the triangle mesh object, representing a relationship of triangles and vertices, determining boundary edges and vertices, computing a series of surface points, and generating a surface line. In exemplary embodiments of the present invention this technique can be used to cut a mesh surface along the line generated. In exemplary embodiments of the present invention a surface line can be generated from start point A to end point B along an arbitrary curved surface based on the start point and the direction of a vector from the start point to the end point. In such embodiments a point having a small displacement away from the start point can be defined as a reference point, and such reference point can be rotated along an axis defined by the normal of a defined plane to obtain an initial surface point. By repeating the above process using each obtained surface point as a new start point a surface line can be generated from point A to point B on a voxel object's surface. In exemplary embodiments of the present invention such surface lines can be used to perform measurements of volumes of such voxel objects.

摘要： A system and method for creating a surface for an arbitrary segment of a three-dimensional data set are presented. In exemplary embodiments according to the present invention the method includes initially identifying a set of surface voxels of the segment. For each voxel in the set information as to which of its neighbors are inside voxels can be obtained, and the results can be utilized to determine the location and direction of a polygonal surface dividing the voxel. The surface can then be obtained by connecting all of the polygonal surfaces. In exemplary embodiments according to the present invention the polygonal surfaces can comprise triangles. In exemplary embodiments according to the present invention the surface can be displayed in either a wireframe mode or a solid mode. In exemplary embodiments according to the present invention mesh reduction can be implemented to reduce the number of polygons in the final surface. In exemplary embodiments of the present invention the volume bounded by the mesh surface can be calculated. Additionally, if the mesh surface generated is not a closed surface, as when, for example, the segmented object has been cropped prior to generation of the mesh surface, any "holes" within it can be closed by a mesh and then the volume can be calculated.
