This is an environment model created using only NURBS in Autodesk's Maya for a project on MSc Animation & Visualisation course (Dec 2013). I used my own kitchen as reference and covered many techniques in creating models using NURBS.
I wrote detailed posts about the creation of this on my Master's blog which can be viewed HERE.
This is the original photo I took to base my NURBS environment model on.
A closer look of the NURBS environment model.
