Another real-time raytracer is on the streets, this time from Numenus.  Their ‘RenderGin’ product can load 3D models from a CAD systems and then use their ‘direct NURBS’ technology to render them in seconds without any triangulation.

RenderGin is the best application for rendering extremely large scenes. It requires around 2 GB of memory to hold a scene with 25 Million polygons. That makes around more than 200 Million polygons on a 16 GB machine. Imagine the possibilities. And the best is: The number of triangles does hardly affect the performance – that’s right, even massive scenes are rendered just as fast as one with only one million.
