Talk:NV1

From Wikipedia, the free encyclopedia

The intro to this page is extremely abrupt, and unclear. What was the NV1? We know when it was released and what it had, but not what it is. I would fix it my self, but I dont know what it is.

Hope I've fixed this now ThomasHarte

[edit] Quadratic?

It rendered quadratic surfaces? That can't be right. Quadrilaterals, maybe? Is there an article that details this rendering approach and how it differs from polygonal rendering? Phlake 14:58, 5 November 2006 (UTC)

NV2 and the Sega Saturn used the same technique. I believe it's actually called "quadratic texture mapping". I bet a Google search would find some good info. --Swaaye 21:23, 5 November 2006 (UTC)

After some looking, I agree that's the term. I have not yet found any detailed information about how it works or how it differs from the conventional polygonal rendering methods, however. Still looking, there. -- Phlake 19:30, 6 November 2006 (UTC)

From [1]: "In addition, the Diamond Edge 3D can create realistic 3D graphics by using nine control points to create a curved surface, called quadratic texture mapping (QTM)." The Sega Saturn used plain quadrilaterals, so there really is very little in common between the two. 85.156.236.246 12:20, 6 May 2007 (UTC)
