Hi all,

I’ve created a new [extension](https://github.com/cpinter/SlicerGridSurface/tree/master) based on the Bézier surface markup by @RafaelPalomar. I added the NURBS interpolation type to be able to create surfaces more intuitively and made some improvements and generalizations.  
We are planning to further improve this markup (fitting to model/segmentation, shared edges, etc.), and expect it to be around for a while.

It is all ready ([see PR](https://github.com/Slicer/ExtensionsIndex/pull/1796)), however, questions have arisen about its name. Currently it is called GridSurface, but it does not describe its purpose too well, and seems to be too technical. **I’d like to ask for your help in finding an appropriate name.**

Some of the ideas so far:

- Surface patch
- Surface markup
- Surface warp
- Curved surface
- Curved plane

Here’s a very short video that shows how it looks:
