We concentrate on the market places which need the application of NURBS modeling technologies, such as Reverse Engineering, Metal forming design, 3D Modeling for Entertainment and so on.

Our available products are Rhinoceros® Plug-ins and stand-alone applications:


( RhinoResurf v5.034 for Rhino 8 and Rhino 7 ) Download the trail version to evaluate RhinoResurf v5.034 for Rhino 7and Rhino 8.

( RhinoResurf v4.565 for Rhino 6/7/8 ) Download the trail version to evaluate RhinoResurf v4.565 for Rhino 6/7/8.

( RhinoResurf v4.199 for Rhino 5(64-bit) ) Download the trail version to evaluate RhinoResurf v4.199 for Rhino 5(64-bit).

RhinoResurf for Rhino, a reverse engineering tool that gives Rhino the ability to reconstruct NURBS surface(s) from mesh or point cloud with specified precision. RhinoResurf also provide features for free-form surface modeling from polygon lines(mesh).

Try RhinoResurf (32-bit and 64-bit).

RsMesh2Surf (new)























NiRen(OBJ_mesh_to_solid) ( new )is a stand-alone application that helps user blend NURBS surfaces from OBJ polygon meshs.

It can import .obj file and export NURBS surface to .igs file.

When you have any polygon mesh created from CG software ( e.g Maya) and would like to blend high quality NURBS surfaces, this small software may help you.

Different from Mesh_to_single_NURBS , the NURBS surfaces here do not fit to the OBJ mesh.

Point_cloud_to_NURBS ( new ) is a stand-alone application that fits a point cloud/mesh to NURBS surface.

The features include:

1. Import point cloud file formatted by .xyz and .txt ;

2. Fit point cloud/mesh to a NURBS surface ;

3. Export the surface to .igs file;

4. Controllable fitting precision. The maximum deviation between points and surface can be specified;

5. Controllable surface smoothness. The surface's smoothness can be adjusted by 5 levels;

6. Handle large scale data. Surface control point number can reach 300X300 which enables the program to fit large scale data, e.g terrain model for survey;

7.Generate mesh from point cloud; Export mesh data to STL file;

8. Easy to use. Just click one button to create surface from point cloud/mesh.

Resurf(Automatic_surface_from_mesh) is a stand-alone application that includes the following features:

1. Automatic surface generation from closed mesh;

2. fit an open mesh to a single NURBS surface;

3. fit a point cloud to NURBS surface;

4. blend NURBS surfaces from OBJ polygon mesh.

It can import point cloud/mesh file and export NURBS surface to .igs file.

"Thanks very much for Rhino Resurf. This software is fantastic and we are very pleased with its performance." ----Tom Werner , Business Development Manager - Terrestrial Laser Scanning(VEKTA)

"Fantastic! This is a really really great product- thanks so much for your efforts to develop it! For me the single surface over mesh works great to create core side offsets when making wall thickness parts that need to be nurbs. I use the rhino mesh offset to offset the entire model at one time, then use resurf to create a nurbs surface that I can booleen from the original model." ------ Kyle Houchens owner of The Outside Digital Art and Design

"Thank you very much! Your advice has payed off and a (very) acceptable surface has been created! This was very helpful. " -----Gijs Rikken, MVRDV

"You and certainly resurf !! Work very well, as you can see i open perfectly your igs and I have a body with volume and mass....." ----- Cordialement. Fran?ois Maniquet

"We were very impressed with your product - thank you! " ------- Chris Hoyle, Technical Director rFactor Pro

"Thank you. The new plug-in works fabulous ! I appreciate your help!" ------- Erik Lander
