SubD-NURBS Overview
SubD-NURBS is the first released product produced by IntegrityWare's Gem Development Initiative. SubD-NURBS is a software toolkit or library that provides the ability to bridge the gap between Subdivision Surface (Sub-D) modeling and NURBS modeling. SubD-NURBS provides tools to convert Sub-D meshes into high quality NURBS surfaces. Check out our Gallery for examples of NURBS models created from Sub-D and quad dominant meshes.
Benefits
Neither Sub-D modeling nor NURBS modeling can effectively solve all 3-D design problems. Each has strengths and weaknesses. Sub-D modeling is great at producing and modifying complex freeform shapes with smooth surfaces. NURBS modeling is good at combining shapes via. Boolean and Feature operations as well as refining shapes with operations like filleting, blending and face editing. We really see SubD-NURBS as a novel and powerful unification piece between these two technologies. Some possible work flows for products built using our SubD-NURBS library include:
- CAD and Architectural Systems wishing to import Sub-D Meshes
- Sub-D based graphics programs wishing to convert and export as NURBS for CAD systems.
- CAD or Sub-D modeling systems wishing to present an integrated environment where Sub-D and NURBS modeling tools are integrated into a single environment.
Please see our Workflows page for additional information on how SubD-NURBS can fit into various work flows. You can see more detailed work flows in various industries on the following pages: Organic Modeling, Automotive, Architectural, Industrial Design, Artistic Design. SubD-NURBS has been tested utilizing Sub-D models produced by a variety of graphics systems. You can see many of those test models in our Gallery. We want to specifically thank Modo and Turbosquid for allowing us to utilize some of their models for testing and displaying on our web site.
To see an example application of the SubD-NURBS technology, please visit www.nPowerSoftware.com, and see our Power SubD-NURBS plugin for Autodesk 3ds Max. You can also watch video tutorials of how this technology can integrate Sub-D modeling and NURBS modeling.
