The use of data structures for displaying images is described: A first minimal data structure. In this structure only that information needed to show the data in the form of a 3D image, either wire mesh or rendered, to the user, is loaded into memory, e.g. the RAM memory. No additional information about the data structure is generated. For example, no connectivity data is loaded into memory. Typically this memory state is used for “read-only” purposes. In other words, the data objects are not to be modified. A second Rich (Flexible) data structure. In this structure, information, which a typical application holds to perform operations on the data, will be kept in memory, e.g. a RAM memory. Optional examples of extra information needed are, connectivity data such as neighbor information, some data flags for polygons, e.g. triangles and vertices, references to next and previous vertices and polygons, e.g. triangles, etc. In order to perform complex operations on big datasets in a somewhat efficient way, such extra information is preferred. A third data structure mainly in the non-volatile memory. In this structure the bulk of the data will be put into the non-volatile storage again, but in such a way that it can very easily be converted into one of the other memory structures again that are mentioned above. The structure in RAM will be similar as in 1 or 2, but will contain a reduced version of the data: for instance the 3D model will be described with less polygons, ultimately with only 6 polygons (the bounding box).

A vascular stent comprising a drug-eluting outer layer of a porous sputtered columnar metal having each column capped with a biocompatible carbon-containing material is described. This is done by placing the stent over a close-fitting mandrel and rotating the assembly in a sputter flux. The result is a coating that is evenly distributed over the outward-facing side of the stent's wire mesh while preventing the sputtered columnar coating from reaching the inward facing side where a smooth hemocompatible surface is required. The stent is then removed from the mandrel, exposing all surfaces, and finally coated with a layer of carbon such as amorphous carbon or diamond-like carbon. The carbonaceous coating enhances biocompatibility without preventing elutriation of a therapeutic drug provided in the porosity formed between the columnar structures. The result is a stent that is adapted to both the hemodynamic and the immune response requirements of its vascular environment.
