Polygon (computer graphics)
Polygons are used in computer graphics to compose images that are three-dimensional in appearance. Usually triangular, polygons arise when an object's surface is modeled, vertices are selected, and the object is rendered in a wire frame model. This is quicker to display than a shaded model; thus...

NV1's biggest initial problem was its cost and overall quality. Although it offered credible 3D performance, its use of quadratic surfaces was anything but popular, and was quite different than typical polygon rendering. The audio portion of the card was of questionable quality, receiving ratings of merely acceptable quality in reviews, with the General MIDI

, and so the unique and somewhat limiting support of these gamepads was of limited benefit. Nvidia, by integrating all of these usually separate components, raised their costs considerably above what they would have been if the card had been designed solely for 3D acceleration.

 audio standards, often required 2 sound cards be used, or a sound card with a MIDI daughtercard connector. Additionally, NV1's 2D speed and quality were not competitive with many of the high-end solutions available at the time, especially the then-critical-for-games DOS graphics speed. Many consumers were simply not interested in replacing their often-elaborate system setups with an expensive all-in-one board and so the heavy integration of NV1 hurt sales simply through inconvenience.

While demos of quadratic rendered round spheres looked good, experience had proved working with quadratic texture maps was extremely difficult.
