Continous Multiresolution Models are a LOD (level of detail) technique in computer graphics which addresses the problem that scenes contain too much geometry when all of the visible objects are rendered at their full geometric resolution. While algorithms along that line have long been available, most modern game/3D-engines implement the much simpler technique of discrete LODs instead. Discrete LOD techniques are widely known for the annoying visible artifacts they produce at the moment the switch between the different resolution models occurs, a drawback unfit for the visual quality of the next generation of 3D/game applications.

The GTP GeometryLib supplies a Multiresolution LOD Solution which addresses the shortcomings of previous approaches by giving developers access to a complete package of solid technology which supplies:

  1. A fast image based simplification algorithm to efficiently create high quality MLODs without human intervention.
  2. Multiresolution triangle strip generation taking into account topology and texture of the base model.
    Triangle strips are the most efficient way to overcome the bandwidth bottleneck between the main processor and memory on modern high performance graphic cards, thereby vastly speeding up the rendering process.
  3. A memory & runtime efficient compressed multiresolution mesh format that contains triangle strip information, avoiding the need for costly on-the-fly tristrip generation.
  4. A new multiresolution model specially fitted for plants allowing for an incredible amount of close up detail for e.g. leaves,
    while at the same time supplying simplified representationions for the fast rendering of objects which are further away.
