Uhm, no. Because, today's 3D-Graphics accelerators are vertex based. So, models who are NURBS-based were recalculated into vertices to render properly. Earlier, 3D-Graphics were based on NURBS. The problem was, that NURBS werent very robust. You couldnt do hard-surfaces. And regarding that texture mapping was invented later, were vertex-based 3D-graphics dominated the world, the whole thing sucked.
So, to render NURBS on today's graphics-accelelarator, you need to recalculate them into vertices. This process is time-consuming and ineffizient. A NURBS model would be 5 million vertices (around 7 million polies, eh) as recalculated. A tough modeler could model the same shape with 50k-100k polies.
