Consider the following two wire frame vessels. This algorithm does not always generate the shaded drawings that you might expect. Two vertices are deemed to be connected if there exists a path of edges between the two vertices.įinally, for each set of connected vertices, the smallest convex hull enclosing the set is drawn. The remaining edges are used to partition the vertices into sets of connected vertices.
These edges are now handled and are excluded from the remainder of the procedure. This allows you to use such edges to visualise parts of the structure that are not solid, e.g. diameter not '~') are drawn as cylinders. When the wire frame is specified by edges, OrcaFlex uses the following procedure to generate a surface from the wire frame vertices and edges.įirst any edges with numerical diameter (i.e.
This typically results in a good representation of the object in shaded graphics view, and so it is usually preferable to specify the wire frame by panels where possible. If the wire frame data is specified by panels, then these are used directly to define a surface. The wire frame drawing data comprises vertices and either edges or panels, but OrcaFlex needs a solid surface for the shaded graphics representation. By default, for shaded 3D views, vessels are drawn using the wire frame data.
