Topological mesh modeling examples converted to NURBS surfaces

In this category you can find 3D models of various 3D shapes that we have drawn in TopMod software. 
 
TopMod is a manifold mesh modeling software that allows you to create high genus shapes. The software is free and you can download it and read more about it at the following link: Topological Mesh Modeling

The program reads and writes .obj files so that it is compatible with a large number of polygonal mesh modeling software. TopMod software generates as output 3D mesh models; in order to make NURBS 3D models, 3D CAD software Rhinoceros and its plug-in T-splines have been used.
 
In the pictures you can see how the 3D models look like and below there are links to download.
 
All the 3D models in this category are under Creative Commons licenses. Check for each 3D model if commercial use is permitted.
 
The 3D models in this category can be downloaded either as polygonal mesh 3D models (.obj or .blend file formats) or as NURBS 3D models (IGES, STEP, Parasolid (x_t) file formats). 3D models of very complex shapes will not be published in NURBS formats because their files are too large.
