NiRen

NiRen is a stand-alone application for Windows.

This software can let user import OBJ polygon mesh, create NURB surafce from the mesh and morph the surface by editting mesh. The feature includes:

1. Import polygon mesh file formatted by .obj;

2. Create NURBS surfaces from the polygon mesh, the NURBS surfaces are watertight and exact G1 transition;

3. Morphing the NURBS surfaces by editting polygon mesh;

4. Export the surface to .igs file;

NiRen is easy to use. Just click one button to create NURBS surfaces from mesh polygon mesh automatically, then you can morph the geometry by your idea.

 

Note:

Please read the License Agreement before using the software.
